Christopher Ward Introduces Apr 23, 2025

Christopher Ward Introduces the C12 Loco

Out to replicate the success of the Bel Canto and prove it’s not a one-hit wonder, Christopher Ward has introduced the C12 Loco. While the integrated bracelet look is now commonplace, the Loco breaks new ground for the British brand in terms of its differentiated movement architecture, and features an inverted free-sprung balance on the dial side of the watch. Spiritual successor to the Bel Canto, the C12 Loco paints a picture of Christopher Ward’s ambitions as a brand. Like Louis Erard, which is on a similar mission to make traditional craft and independent design more accessible, Christopher Ward is looking to redefine what collectors should expect from entry level watchmaking. Initial thoughts The Twelve is Christopher Ward’s foray into integrated bracelet sport watches. Its launch in 2023 was not without some controversy, being seen as too similar to the Czapek Antarctique; it turned out both designs came from the mind of designer Adrian Buchmann. Despite the rocky start, the collection has been a commercial success and the brand has done a commendable job developing the line-up and keeping prices in check. The Loco is the most ambitious Twelve to-date, with an off-center time display that opens up space at six o’clock for an exposed balance wheel and escapement. Like the Bel Canto, the watch does not feature the Christopher Ward brand name on the dial. In an era when attention is the name of the game, it’s nice to see a small brand with the confidence to let...

De Bethune Turns to Swizz Beatz for Kind of Two GMT

The third iteration of De Bethune’s swivelling, double-faced watch is the Kind of Two GMT “Season 3” conceived in collaboration with American rapper and watch enthusiast Swizz Beatz. Powered by the hand-wound DB2517 movement, the watch indicates one time zone on the front and another on the reverse, with both sides able to be worn face up thanks to patented, pivoting “floating” lugs. Initial thoughts The Kind of Two series employs a useful reversible case, cleverly using the “floating” lug construction of the DB28 to create a double-faced watch. Here one dial is traditional with blued steel hands, and the other an open-worked face revealing the movement that also has a regulator-style display for the second time zone. The clever approach with a unique movement is typical De Bethune, although this loses some novelty as the third double-faced watch in the De Bethune line-up. The Kind of Two GMT is definitely one of the most elaborate two time zone watches on the market, but at over US$200,000, it is pricey for a GMT, even by the standards of independent watchmaking (Voutilainen’s GMT, for instance, costs less). Two-faced The “Season 3” edition adopts a restrained palette of black and gold with blue accents. The 43.3 mm by 11.4 mm case is titanium and zirconium, with blued steel hands and a blue-and-black guilloche dial centre on the front showing local time. Notably, this dial includes a jumping seconds that is driven by a secondary escapement visible on ...

Grand Seiko s Tentagraph Grand Seiko’s Apr 10, 2025

A New Dial for the Grand Seiko’s Tentagraph

Grand Seiko’s flagship chronograph gets a new dial with the Tentagraph SLGC007 that just launched at Watches & Wonders 2025. Nearly identical to its predecessor, the SLGC001 with a dark blue dial, the new iteration distinguishes itself through a striking grey dial embossed with a pattern inspired by freshly fallen snow. This is matched with contrasting black sub-dials that coordinate seamlessly with the ceramic bezel, setting it apart from the earlier model. Initial thoughts The SLGC001 was a significant milestone for Grand Seiko - serving as the brand’s first mechanical chronograph - the new iteration of the Tentagraph is a just cosmetic variant. It has all the strengths and weaknesses of the original, though the dial is more attractive. This refreshed dial is far more appealing than the original in blue, as blue is somewhat overused in sports watches. The “panda”-esque black registers are also a nice touch that add to the sporty design. Priced at US$14,700, the Tentagraph SLGC007 is priced reasonably – but not quite the same value proposition as the average Grand Seiko. The Tentagraph has an impressive list of features, most obviously the in-house cal. 9SC5 with Grand Seiko’s proprietary Dual Impulse Escapement, and a high level of fit and finish, but the movement is modular in construction, which should not be a case for a flagship chronograph from a respected watchmaker. Nature inspired once again As is often the case with Grand Seiko dials, the SLGC007...

Rolex Land-Dweller I won't belabor Apr 9, 2025

Editors' Picks: Our Favorite Watches & Wonders 2025 Releases

Watches & Wonders 2025 has come and gone and there was no shortage of unexpected releases and divided opinions. The editorial team here at Teddy was on the ground covering all the new launches, and afterward we asked them to name their favorite release from the show. It’s not an easy task, but we are going to have a few more of these post-show Editors’ Picks articles in the coming days that will expound a bit more on what we thought. For now, let’s get to our overall favorite picks from Watches & Wonders 2025. Danny Milton: Rolex Land-Dweller I won't belabor the point here, considering I penned about 2,000 words on this watch at launch, and helped produce our hands-on coverage at embargo. The Land-Dweller is seriously big news, and in all candor, is the watch of the show, full stop. It plays on nostalgia via its callback to the design language of integrated sports watches from Rolex in the 1970s. It introduces an entirely new design template in the modern Rolex context via a new case; a new, flat Jubilee bracelet; patented stick markers; new open applied numerals; new hands; a new counterweight on the seconds hand; and a new honeycomb dial, not to mention a new fluted bezel design. But the real star of the show is a silicon escapement made from the ground up. Dynapulse is perhaps Rolex's greatest innovation and results in a new 5Hz beat rate while maintaining accuracy, shock resistance and antimagnetic properties. But above all else, the watch honestly looks and wear...

Grand Seiko Debuts Apr 8, 2025

Grand Seiko Debuts the Angular, Sporty Tentagraph Tokyo Lion

Grand Seiko’s flagship mechanical chronograph has been reimagined as the Sports Collection Tokyo Lion Tentagraph SLGC009. Executed in the brand’s proprietary “Brilliant Hard Titanium”, the oversized, facetted case is inspired by the paw of a lion, the historical emblem of Grand Seiko. This is the first time the Tentagraph movement is being combined with the Tokyo Lion case, setting it apart from the original model that was in the classic Grand Seiko Evolution 9 design. Initial thoughts While the original Tentagraph was conventional in style, the Tokyo Lion edition is big and bold. The watch has presence on the wrist. The case is large at 43 mm wide and almost 16 mm high, with its many facetted surfaces catching the light nicely. While the concept of a lion-inspired case might sound gimmicky, the new Tentagraph has its own appeal. The size and style makes this less of a low-key everyday watch than the first Tentagraph, but definitely more striking and original. Even though the Tokyo Lion case is arguably an acquired taste, I like this more than the original. At US$16,400, the Tokyo Lion Tentagraph is one of Grand Seiko’s priciest models in non-precious metal. But it is a flagship watch with a latest-generation movement, the cal. 9SC5, which incorporates the proprietary Dual Impulse Escapement and a free-sprung balance. The only shortcoming of the watch is the modular construction of the movement. Ten beats per second While the Tokyo Lion case design has been emplo...

Grand Seiko Redefines Accuracy – Again Apr 1, 2025

[VIDEO] Grand Seiko Redefines Accuracy - Again: Introducing the 9RB2 U.F.A. Spring Drive Caliber

2022: the Kodo constant force tourbillon. 2023: the Tentagraph hi-beat mechanical chronograph. 2024: the 9SA4 manual wound, hi-beat, dual-impulse escapement caliber, and Kodo Daybreak. It’s easy to forget that Grand Seiko has brought the proverbial heat to Watches & Wonders every year since the fair started, unveiling something that one could call “revolutionary” for the brand, if on varying scales. Well, it’s looking like 2025 will continue the trend with the introduction of Spring Drive Caliber 9RB2, the first caliber with U.F.A., or Ultra Fine Accuracy, designation. Before proceeding, there are two important concepts to understand: Spring Drive and Grand Seiko’s history with acronyms (which, if you know, feel free to jump two paragraphs ahead). Starting with the former, the elevator pitch, which I will take from our article dedicated to the topic is “Spring Drive combines the best of mechanical watchmaking and the best of quartz timekeeping to create a state-of-the-art caliber that lacks the weaknesses inherent to both of these movements.” A bit deeper, Spring Drive movements use the energy stored in a traditional mainspring to drive their proprietary “Tri-synchro” regulator, which replaces the classic lever escapement. It consists of a glide wheel, the rate of which is controlled by an electromagnetic brake, and is essentially regulated by an integrated circuit with a quartz oscillator. The result is a mechanical movement with quartz-like accuracy and...

Rolex Land-Dweller Cal 7135 Patents Mar 31, 2025

Insight: Rolex Land-Dweller Cal. 7135, Patents and Innovation Explained

Rolex has entered uncharted territory with the Land-Dweller, arguably the most advanced and radical creation from a hitherto conservative brand. The Land-Dweller is significant, perhaps even game changing, not because of the integrated bracelet or patented solid lume, but because of the cal. 7135, a new calibre with an all-new double-wheel escapement known as Dynapulse and a ceramic balance staff. (This story details the technical advances in the movement; for a review of the watch, check out the accompanying story.) The Land-Dweller 40 mm in platinum The fundamentals Why is it significant, or even game changing? The cal. 7135 is the first in-house, serial production Rolex movement that is high frequency, beating at 5 Hz or 36,000 beats per hour. All things being equal, a higher frequency promises superior timekeeping. Despite the higher frequency, the cal. 7135 still has a 66-hour power reserve. That’s thanks in part to the Dynapulse escapement which is 30% more efficient than a conventional Swiss lever escapement, while occupying essentially the same volume of space. The balance assembly of the cal. 7135 Dynapulse is one of several innovations that make the cal. 7135 a landmark, especially since it will be produced at scale. While Rolex has traditionally been associated with incremental innovation, the cal. 7135 is a revolution. The Land-Dweller is the subject of 32 filed patents, 18 of which are unique to the watch. Moreover, 16 of the patents unique to the watch are ...

In-Depth: Rolex Land-Dweller

The most discussed debut of Watches & Wonders 2025, the Rolex Land-Dweller is an entirely new model with a new case and bracelet, but that’s not why it is significant. While Rolex is conventionally associated with incremental innovation, the Land-Dweller is game changing. Not because of the design, but because it’s equipped with perhaps the ultimate mechanical movement produced at scale in contemporary watchmaking, a calibre that’s the subject of 16 patents. (The finer technical details can be found in our accompanying story.) The cal. 7135 inside the Land-Dweller is a new, sophisticated calibre equipped with an indirect-impulse, double-wheel escapement that’s entirely in silicon – christened Dynapulse – matched with a ceramic balance pivot. And it’s a high-frequency calibre running at 5 Hz or 36,000 beats per hour. Cumulatively, that makes for a superior timekeeper on the wrist. The Land-Dweller debuts in two sizes, 36 mm and 40 mm, in three basic variants: white Rolesor, Everose gold, and platinum. There are also a handful of high-jeweller versions. The Land-Dweller in white Rolesor on Roger Federer’s wrist. Image – Rolex Initial thoughts The Land-Dweller is both surprising and predictable. The styling is surprising; the integrated bracelet echoes historical watches like the Oysterquartz and ref. 5100 Beta 21 but I never expected it.

Insight: Regulating a Mechanical Watch Movement

A mechanical watch is not always spot on; less-than-perfect timekeeping can happen, often due to an unruly oscillator. The solution is direct adjustments to the hairspring and balance assembly, either slowing down or speeding up the oscillator, a practice known as regulation. Watchmakers have devised multiple innovations to achieve this, including the free-sprung balance, exemplified by the Gyromax of Patek Philippe and Microstella of Rolex. While a simple concept in principle, the mechanics and practice of regulation are nuanced. Here we’ll delve into the theory of regulation and the primary regulating systems: the curb-pin regulator and the free-sprung (or variable inertia) balance. The Lange L043.4 with a screwed balance inspired by pocket watches Basic concepts In order to better understand watch regulation, we need to first cover some of the basic physics behind the watch oscillator: The component responsible for the running rate of a movement is its regulating organ. The regulating organ is made up of a hairspring paired to a balance, which together are also known as a harmonic oscillator. The natural oscillation period is the time it takes the balance to make a full swing, back and forth. The period is made up of two vibrations, one for each direction of the balance motion, with the escapement being unlocked at each vibration. Notably, the natural period of a balance wheel is intrinsic to itself and does not depend on the escapement type or the going train ratio. ...

Grand Seiko Heritage Collection 45GS SLGW005 Feb 14, 2025

Review: Grand Seiko Heritage Collection 45GS SLGW005

Grand Seiko announced in September last year a vintage remake inspired by the 45GS of 1968, the Heritage Collection 45GS Re-creation, which was launched as the SLGW005 in steel and the SLGW004 in yellow gold. In contrast to the many recent Grand Seiko releases with modern styling, the 45SG Re-creation is refreshing in being a revival of an iconic design, right down to the double-signed dial. Yet, the model also sports the brand’s latest generation manual-wind movement, the 9SA4. As the more accessible model of the two – retail is a little under US$10,000 – the steel SLGW005 deserves a closer look to understand how it smartly melds old and new. Initial thoughts Aesthetically, the SLGW005 stands out as a distinctively vintage design, from the case and dial to the buckle. This is all the more so since it is the first release since Grand Seiko’s rebranding in 2017, when all models eliminated “Seiko” in favour of only “Grand Seiko”, to feature the brand’s historical double-signed “Seiko” and “GS” dial. I am personally fond of this detail, as the double logo balances the dial aesthetically. But preferences aside, the external components are indeed excellent, from the dial work down to the faceted case. Despite the traditional exterior, the internals are modern – almost paradoxically so. Sporting the brand’s proprietary Dual Impulse Escapement, the 9SA4 inside is entirely different than the 1960s cal. 4520 found in the 45GS. On paper, it is a high-s...

The Journey of Thomas Schnelle

Thomas Schnelle’s journey began in northern Germany, where he pursued studies in toolmaking. After completing his technical college education, Schnelle found himself at a crossroads. While he contemplated studying design, a lack of confidence initially held him back. It was at this juncture that fate intervened, leading him to Chronoswiss, then owned and operated by Gerd-Rüdiger Lang in Munich.  Chronowiss and Lang could be a long story in itself since Lang had mentored and influenced a lot of the next generation of watchmakers and brands. In 1991, 21-year-old Schnelle approached Lang, and it paid off when Lang entrusted the young newcomer with a significant project – creating a series of 99 escapement models. Schnelle officially started his career in the watchmaking industry as a supplier to Chronoswiss, later becoming a freelancer for the Bavarian brand.  In 1995, Schnelle completed his watchmaking studies in Würzburg, and had the honor to be recognized as Germany’s best young watchmaker in competition. He continued to work as a freelancer for Chronoswiss until 2012, when Lang sold the company to the Ebstein family in Switzerland. Schnelle also repaired Cartier Tank watches for nearly 20 years for the Richemont group. He even took on side projects like milling air stream chambers for Infineon, and offering his technical design services.  In August 2024, I visited Schnelle at his home atelier in Munich, and his workshop was filled with photographs, technical de...

Up Close: Hermès Arceau Duc Attelé Repeater Triple-Axis Tourbillon

Hermès is a brand with a distinctive, often whimsical, visual identity that translates well across products, even on its most complicated watches like the Arceau Duc Attelé, which combines a triple-axis central tourbillon (containing a high-frequency escapement) with a minute repeater featuring novel “tuning fork” gongs. Large, thick, and very complex, the Duc Attelé still manages to capture the elegant aesthetic of the brand, even in subtle details of the H1926 movement, like horse-shaped hammers for the repeater. Customised for Hermès, the calibre has an intricate, dense construction but is recognisable as being produced by a specialist. Initial thoughts The Duc Attelé demonstrates the strength of the Hermès house style. On the front, it looks elegant despite the size, while the movement feels appropriate even though it is third party. The watch does sit big on the wrist, though the titanium version is a little lighter in weight and visually smaller due to its dark colours. But the Arceau case has tiny lugs, so it doesn’t feel clunky. And although the case is almost 20 mm high, a good part of that is due to the highly domed crystal that accommodates the tourbillon’s height. All of the design elements, however, give it an elegant feel. These include the Breguet numerals on the domed chapter ring and the “Lift” motif tourbillon cage modelled on the elevator in the brand’s flagship store in Paris. But more than anything else, this is a watch characterise...

Konstantin Chaykin s thinnest-watch-ever Dec 23, 2024

Best of 2024: Independent Watchmaking

Independent watchmaking continued its hot streak in 2024, with interest and demand for this niche segment holding up better amidst an industry-wide slowdown. But surprisingly – or unsurprisingly depending on how you look at it – there were relatively few outstanding new creations from the indies. A handful, however, did stand out. We look at the team’s highlights of the year, which range from Konstantin Chaykin’s thinnest-watch-ever to the debut by Swiss-based Japanese watchmaker Takahiro Aigaki. Aigaki Direct-Impulse Tourbillon – Brandon Moore I still remember the moment I stumbled across Takahiko Aigaki’s Instagram profile earlier this year, because the close-up image of the tourbillon cage made me do a double take. Sure, it was well finished, but in 2024 good finishing no longer provides the competitive advantage it once did; the top end of the market is just too competitive. No, what struck me was the unusual double direct-impulse escapement. When the Direct-Impulse Tourbillon was finally revealed, it was worth the wait. While arguably a bit plain on the outside, the movement exhibits a degree of grace and technicality that is still quite rare. The watch is truly a sleeper, in the sense that the case and dial reveal little of the horological magic within.

Up Close: Aigaki Debuts with the Direct-Impulse Tourbillon

Founded by a Japanese transplant to Switzerland, Aigaki is making its debut with the impressive Direct-Impulse Tourbillon. Though relatively youthful, brand founder Takahiko Aigaki is a watchmaker of the old school who developed the watch and then makes almost all of it by hand. Produced almost entirely in Takahiko Aigaki’s own home-workshop with hand-operated tools, the Tourbillon is characterised by its hand-engraved silver dial and a finely-finished movement combining unique architecture with a proprietary escapement. Initial thoughts I’ve been following Aigaki on Instagram for several months, having become intrigued by the unusual in-line architecture of the movement, and its symmetrical direct-impulse escapement. Initially, only the movement components were shown, but even this sneak peak was enough to pique my interest. Now that the watch has been unveiled, I feel like it was worth the wait. The Tourbillon is a compact, 37 mm timepiece with a clean aesthetic and domed crystal that lends it something of a vintage feel. On its face, the appearance is simple, but the watch instantly conveys the sensation of a finely-crafted object, especially when you turn it over. But even on the front, the details of the dial give away the fact that it is hand-made. Interestingly, there is no ink or paint used on the dial. All of the dial markings and elements are hand-engraved using traditional tools; the brand name is engraved with a hand-operated pantograph. The Tourbillon is v...

Hands On: Urban Jürgensen and Derek Pratt Oval Pocket Watch

A storied example of artisanal independent watchmaking, The Oval was the masterpiece by Derek Pratt (1938-2009), perhaps the greatest unknown watchmaker. Pratt began work on the Oval in 1982 as his magnum opus, the ultimate realisation of his aesthetic and technical vision. While his work for Urban Jürgensen is perhaps his best known, Pratt was an independent watchmaker with a diverse repertoire, including working with George Daniels on the co-axial escapement. Amongst his creations was a replica of John Harrison’s H4 marine chronometer. These projects, as well as the fact that the Oval was mostly hand made, meant the pocket watch took some two decades to complete. Although it’s a sizeable watch, the Oval is finely detailed, reflecting the high level of Pratt’s craft and the years he invested in creating the watch from scratch. Beyond its artisanal execution, the Oval also stands out for its technical achievement. Besides a detent escapement, the Oval also contains a horological first – a constant force mechanism integrated within the tourbillon – along with a thermometer, power reserve display, and moon phase on the dial. We took an in-depth look at the Oval in 2021, thanks to its current owner, Dr Helmut Crott. But now as the Oval heads to the auction block at Phillips, it’s worth one last look before it disappears into a collection.

Ulysse Nardin Unveils Freak X with Grand Feu Enamel Dial

Ulysse Nardin’s entry-level Freak has been dressed up with a flinque enamel dial in a limited edition for Ahmed Seddiqi & Sons, the Middle East’s most prominent luxury watch retailer. The Freak X Enamel Seddiqi features a “Yas Blue” guilloché enamel dial with the signature carousel carrying an oversized oscillator and silicon escapement that acts as a minute hand. Initial thoughts The Freak X is a descendent of the original Freak, but simplified for user-friendliness and affordability. The Seddiqi edition combines the appeal of the Freak X with an artisan ally decorated dial – a combination of contrasts that are complementary. While the enamel might seem contrary to the high-tech nature of the Freak X, it complements the aesthetics of the watch. The striking, translucent enamel forms a pleasing backdrop for the carousel. Priced at AED154,000 or around US$42,000, the Freak X Enamel Seddiqi is a little more expensive than the base model Freak X, but still amongst the most affordable Freak models. Inversed calibre In 2001, Ulysse Nardin revolutionised watchmaking the Freak, a watch that reimagined the conventions of movement construction with an unprecedented design that relocated the going train and oscillator to double as the minute hand.

Glashütte Original Inverts the PanoLunar

One of the first brands to invert a movement and showcase it on the dial, Glashütte Original just released the PanoLunarInverse, a sibling of the PanoLunarTourbillon and PanoMaticInverse. Like the earlier models, the PanoLunarInverse has key parts of the movement on the dial, including the balance wheel, escapement, and three-quarter plate that’s finished with with pyramid guilloche. In addition, it features the brand’s oversized Panorama date at two o’clock and a large moon phase display. Initial thoughts Older Pano models tended to be conservative in style. The PanoLunarInverse, on the other hand, is modern in colour and decoration, setting it apart from its Pano siblings. The inverted construction is made more interesting with the pyramid guilloche, while the moon phase adds a bit of romance to the technical appearance of the dial. Some models in Glashütte Original’s Pano collection bring to mind the asymmetrical dial layout of another German brand (which is partly why Glashütte Original has never escaped the shadows of its peers), but the PanoLunarInverse feels original because of the combination of colour, decoration, and complication. Priced at US$42,600, the PanoLunarInverse is one of the pricier watches in the Pano collection, but it is reasonably priced considering the platinum case and movement decoration. This is typical of Glashütte Original, which sits in the accessible high horology segment alongside brands like Jaeger-LeCoultre. Inverse German wa...

Breguet Tourbillon Extra-Plat 5367 Breguet’s Oct 23, 2024

Up Close: Breguet Tourbillon Extra-Plat 5367

Breguet’s ultra-thin tourbillon has been in its catalogue for some years now, but it remains one of the brand’s most sophisticated tourbillon models. The Tourbillon Extra-Plat 5367 is just 7.45 mm high, making it one of the thinnest self-winding tourbillon watches on the market, a feat made possible thanks to clever peripheral winding. Though its movement is the brand’s latest tourbillon calibre, the 5367 is presented in classic Breguet style – with the enamel dial here or as the 5365 with a guilloche dial – and retains the quintessential Breguet elegance. Initial thoughts Unlike Breguet’s flagship tourbillon model, the massive Double Tourbillon 5345, the 5367 is slim, elegant, and feels like a classical Breguet. In terms of proportions the 5367 is comparable to the 7637 minute repeater, but the tourbillon is thinner and importantly, boasts a more modern movement. The enamel dial is available in traditional white or contemporary blue While the 7637 repeater is powered by a movement that has its roots in the 1980s, the 5367 contains the cal. 581, which is instantly recognisable as a recent construction. The most obvious giveaway is the automatic rotor camouflaged on the periphery, while the tourbillon contains a silicon escapement. The modernity of the construction means the cal. 581 lacks the old-school charm of Breguet’s earlier tourbillon movements, but the sophistication of the cal. 581 is undeniable. Not only is it exceptionally thin, it manages an impre...

Nomos Unveils a New Movement with Two Dates at their Annual Forum

I attended the 5th year of Nomos’s annual forum this week, and even though the theme was about design and colors, it was the new manual winding movement that received the most attention.  As a seasoned writer who has closely followed Nomos’s trajectory, I often find myself anticipating the brand’s future moves. However, even with my extensive experience, the unveiling of the Tangente 2date ($2,760-$3,020) caught me off guard. I will be very open about what resonated with me, and what left me puzzled. Let’s begin with the movement itself. The DUW 4601 is a new manual winding caliber with a slim height of 2.8mm, and 52 hours of power reserve. Speaking with Mirko Heyne, head of research and development at Nomos, I learned that the previous manual winding caliber, DUW 4101, had the same height with a normal date complication, 42 hours of power reserve, and not the nice finishing we see on the new 4601. Both have the Swing System, the proprietary escapement developed by Nomos. In summary, the new movement delivers extra power reserve, better finishing, and has an additional date complication while still remaining the same height as the previous movement – that’s because the patented date wheel is integrated into the mainplate. Another significant technical advancement in the 4601 caliber is the quick set date mechanism. You can easily jump forward with the crown in the second position.  When I saw the standalone movement with Mirko, my first impression was the sli...

The Greatest Horological Inventions of All Time: How The Invention of Balance Spring Changed the World

Editor’s Note: Today, we bring you the second part in the new series from Andrew Canter, the Greatest Horological Inventions of All Time. In this installment, Andrew examines the invention of the balance spring, a watchmaking advancement that not only charted a path for the watch industry, but can be said to have legitimately changed the world, enabling accurate, reliable, and portable timekeeping for the first time in human history. Who actually invented it, though, is still a matter of some debate, even after 350 years.  You can find more of Andrew’s work at the Mr. Watchmaster website here. Prior to the Balance Spring Early watches were powered by a verge escapement which was the same type of movement used in the early clocks. The verge is the earliest known type of mechanical escapement that controlled its rate by allowing the gear train to advance at regular intervals or ‘ticks’. Verge escapements were used from the late 13th century until the mid-19th century in clocks and pocket watches. Drawing of a verge escapement (bottom) and balance wheel (top) from an early pocket watch from an encyclopaedia c.1820 In the earliest watches a plain wheel, known as the balance, was used to control the rate of going of the mechanism. There wasn’t a consistent restoring force (such as a fusee), so consequently, its period of oscillation and, hence, the rate of the timekeeper were dependent on the driving force.

Grand Seiko Recreates 45GS Sep 9, 2024

Grand Seiko Recreates 45GS with Calibre 9SA4

Having unveiled the top-of-the-line 9SA4 movement earlier this year, Grand Seiko has now installed the new calibre in a pair of vintage remakes, the Heritage Collection 45GS Re-creation SLGW004 and SLGW005. A limited edition in either steel or 18k yellow gold, the 45GS Re-creation is one of Grand Seiko’s few vintage reissues with its latest-generation calibre that boasts a high-frequency balance and Grand Seiko’s proprietary Dual Impulse Escapement. Initial thoughts This is Grand Seiko’s first remake of the 45GS, but if the new pair look familiar, that’s because Grand Seiko launched a 44GS remake in 2013. Though the 44GS and 45GS are different models launched just a year apart in the late 1960s, they were different models. The 45GS was an upgrade over the 44GS in terms of the movement, though it retained similar styling. In the same manner, the modern-day remakes are most notable for having different movements. Amongst Grand Seiko’s many remakes, the 45GS stands out for the 9SA4 inside. It’s a large, slim, and sophisticated calibre that’s a substantial improvement over the manual-wind movements found in past remakes. Because of the movement, the 45GS remakes are amongst the more expensive manual-wind Grand Seiko models at US$9,700 in stainless steel and US$30,000 in yellow gold. Moreover, the two priced comparably to the SLGW002 and SLGW003, which are modern designs but powered by the same calibre. While not as affordable as other Grand Seiko models, the 45G...

Grand Seiko Just Released Sep 2, 2024

Grand Seiko Just Released a Collector’s Dream Watch!

At Watches & Wonders 2024, Grand Seiko announced the new 9SA4 caliber and the first two watches featuring it, the SLGW002 and SLGW003. As a refresher, the 9SA4 is a manual hi-beat (36,000 bph), 80-hour, time-only caliber featuring their in-house dual-impulse escapement, first seen in the 9SA5. With a power reserve on the back of the movement, beautiful bridge designs and finishing, and a unique “wagtail-bird-shaped” winding click, it set a new bar for Grand Seiko’s mechanical calibers. But, perhaps just as exciting as the movement itself was that the watches featuring it were sized at an idyllic 38.6mm diameter and 9.95mm thickness with a 20mm lug, addressing the naysayer’s concerns around Grand Seiko’s sizing. While a pair of fantastic releases, since introduction, we have been wondering where we will see this movement next. Well, we just got our answer, and I have to tell you, I’m equally surprised and delighted. They went vintage rather than with the new case and a different dial, which would have been most expected. Yes, they decided to bring back, as a limited edition, of course, a “recreation” of the 45GS from 1968. A little history, the 45GS came out a year after the 44GS and featured the same case design, but differed in that it featured the brand’s first hi-beat manual wound movement, the 4520. The SLGW005 – the return of the 45GS The 44/45GS case defines the Grand Seiko “Grammar of Design” as set out by Taro Tanaka, with flat, Zaratsu poli...

Insight: The Geometric Efficiency of Escapements

Mechanical escapements remain the most fascinating and enticing field of horological study even in the 21st century. At its core, an escapement has a simple purpose: restore lost energy to the oscillating organ while regulating the discharge speed of the going train – thus allowing for time measurement. Straightforward as the concept is, executing an escapement well is a completely different affair. The escapement is perhaps the element of the mechanical movement that has undergone the most iterations since its invention. The reason is simple: escapements were, and remain, imperfect systems. In fact, the escapement is often the least efficient aspect of a mechanical movement in terms of energy transfer. That’s why watchmakers and engineers have devised innumerable variants in the search of the ideal escapement.  Explaining escapement efficiency In physics the efficiency of a system is the proportion of useful work done relative to the total work done by said system. The result, measured as a percentage, speaks to the energy conserved within the system. For example, an 80% efficiency means that 20% of the total available energy is lost, with the remaining 80% usefully conserved.  That said, an efficient escapement isn’t necessarily chronometrically-potent, since there are more criteria, apart from energy conservation, which reflect in a movement’s accuracy. The way in which escapement parts impulse to the balance, the proximity of the equilibrium point and the deg...

Armin Strom Gravity Equal Force Aug 1, 2024

(Video) Incredible Watch Engineering from a Brand You Need to Know - Armin Strom Gravity Equal Force

The Armin Strom Gravity Equal Force is not like other watches. At a glance, it clearly doesn’t look like them, but more importantly, it also works a bit differently too, featuring a first in watchmaking. To be clear, it still tells time with three hands, is operated by a crown, and has all of the movement components one expects to find on a watch, from a mainspring to an escapement. But it hides a very cool secret. Something that sets it apart. Hidden within is a little mechanism that helps it be more accurate. It’s not a complication, per say, as it doesn’t add any functions beyond time-telling, rather, it makes for a better watch. The Gravity Equal Force is one of a small handful of watches that attempts to address a fundamental issue with mechanical timepieces: variations in accuracy across their power reserves due to changing torque. As the power reserve diminishes, the torque, or force, decreases, the amplitude of the escapement falls, and the timekeeping becomes less accurate. Watchmakers have addressed this issue in various ways over the last few hundred years, which are often grouped together and referred to as “constant force” mechanisms. The Gravity Equal Force uses a simple, though uncommon, mechanism compared to typical “constant force” systems such as fuseé, chains, and remontoirs called a Geneva or Maltese cross. This mechanism prevents the watch mainspring from unwinding to the point where the torque and, thus, the accuracy really drop off. Ho...

Horage and the Ingenious New Revolution 3 MicroReg

Okay, I admit it. I don’t really care about my watches’ accuracy. Don’t get me wrong, I want my watches to be relatively accurate - and I certainly want them to be in spec - but I want the watchmakers to care about that so I don’t have to. At the end of the day, I just can’t bring myself to care all that much about a couple of seconds over the course of a day. After all, what’s 10 or 15 seconds held up against 86,400? The world doesn’t really operate on that sort of accuracy, and my day-to-day writing about watches certainly doesn’t demand it. That said, while I may not care all that much about accuracy in the abstract, I love it when brands pursue accuracy. I’m a sucker for a clever escapement, a new technique, or a wild swing, and beyond all that, I love the creativity that the pursuit of accuracy tends to elicit. So when Horage announced the Revolution 3 Microreg last week, it certainly caught my eye. The standout feature of the Horage Revolution 3 Microreg, which was made using technology developed by Swiss engineering firm Miniswys, is the ability to regulate the watch at home using a miniature electric motor connected to the escapement’s regulator and controlled by an external dock which allows adjustment in increments as low as 0.1 seconds. Pair this with what is already a COSC-certified movement and what you get is the potential for a remarkably accurate watch that bridges the gap between, as Horage puts it, regulation and reality. One of t...
