Hands-On With The Girard-Perregaux Neo Constant Escapement - Could We Catch The Purple “Butterfly” Inside?

Why use a traditional, coiled balance spring when you can use a 14-micron-wide and 120-micron-“thick” silicon blade instead? With the latter, Girard-Perregaux set out to overcome the inherent challenge of fluctuating power delivery in mechanical watches. The goal for the 235-year-old Swiss watchmaker from La Chaux-de-Fonds was to achieve consistently superior precision. The quest involves […] Visit Hands-On With The Girard-Perregaux Neo Constant Escapement — Could We Catch The Purple “Butterfly” Inside? to read the full article.

Casio Oceanus Retro Tone Collection Adds Two Japan-Only Titanium Watches

Casio has expanded its Oceanus Retro Tone Collection with two Japan-only limited editions for August 2026: the Manta S400 OCW-S400RL-8AJR and Classic Line OCW-T2600RL-3AJR. Both use lightweight titanium cases, solar power, radio-controlled timekeeping and Tochigi leather straps. The idea is simple: modern Casio technology presented with warmer colours and a more traditional character. The Casio Oceanus Retro Tone Collection pairs the green T2600 with the grey Manta S400. Image: Casio. A Softer Retro Tone Look Both watches use half-matte gradient dials that change gently from the centre to the outer edge. Casio creates the effect through a silver layer, colour coating and printed gradient pattern while keeping the dial transparent enough for solar charging. Straight hands and solid bar markers keep the displays clean. The vegetable-tanned cowhide straps come from Tochigi Leather, a Japanese maker founded in 1937 and should soften and develop a darker colour with use. The Lighter Manta S400 Casio Oceanus Manta S400 OCW-S400RL-8AJR with its grey gradient dial and rose-gold-coloured sapphire bezel. Image: Casio. The OCW-S400RL-8AJR is the smaller and more expensive model. Its titanium case measures 46.5 mm long, 41.3 mm wide and only 9.2 mm thick. Without a bracelet, the watch weighs just 38 grams. A frosted sapphire bezel ring carries world-time city codes and receives rose-gold ion plating. The dial is grey, giving the warm bezel and brown leather strap plenty of room to sta...

A Majestic Journey Through Clocks & Watches Made for Royalty: The Enlightened Empress - Maria Theresa and the Mechanics of Wonder

From the imposing astronomical clocks of Tudor England to the exquisite pendant watches of Victorian Britain, timekeeping has long been a symbol of power, prestige, and technological marvel within Europe’s royal courts. This new series explores the fascinating evolution of clocks and watches crafted specifically for royalty, tracing how these intricate masterpieces reflected the tastes, ambitions, and innovations of monarchs. Through the lens of craftsmanship, artistry, and historical significance, we reveal how these royal timepieces marked the passage of dynasties and empires. Maria Theresa was the ruler of the Habsburg monarchy from 1740 until her death in 1780, and the only woman to hold the position in her own right. Though crowned as Archduchess of Austria and Queen of Hungary and Bohemia, her true authority came from willpower, reform, and image-making. Maria Theresa ruled not as a king in disguise, but as a monarch in her own right, one who embraced both tradition and the flux of the Enlightenment. Horology, like art and music, became part of her sovereign language and a way to express her modernising ambitions and cultivated authority. Maria Theresa was born in Vienna on the 13th of May 1717, the eldest daughter of Emperor Charles VI and Empress Elisabeth Christine of Brunswick-Wolfenbüttel. As a child of the Habsburg dynasty, she grew up in the Hofburg Palace (below) surrounded by the rituals and splendour of imperial court life. Although her father’s hopes ...

Introducing the Autodromo Group C Turbo Sport, the Brand’s First Ana-Digi Watch Worn & Wound

Introducing the Autodromo Group C Turbo Sport, the Brand’s First Ana-Digi Watch

Few innovations in automobile engines have been as impactful as the turbocharger, first brought to production cars in the 1960s and popularized in the United States largely thanks to the iconic turbodiesel 1978 Mercedes-Benz 300SD. With a telltale whistle accompanying that extra boost of power, the turbocharger soon became synonymous with motorsports and performance cars of the 1980s: the Audi Quatto’s breathy flutter, the 930 Porsche 911 Turbo’s heartpounding lag, and the Ford Sierra RS Cosworth’s European rally dominance all helped propel the decade into the “golden era” of turbocharged performance.  With their latest release, motorsport-inspired watchmakers Autodromo are bringing another homage to a period of automotive innovation, this time highlighting the Group C “prototype” class of sports cars from the 1980s, many of which featured bold (and sometimes dangerous) turbocharged power. The basis of this new collection is their already-successful Group C digital watch, initially released in 2023, and the new Turbo Sport models draw inspiration from the analog tachometers of turbocharged ‘80s motorsports legends to create an ani-digi design that straddles the classic and modern eras of automotive and horological design.  First, the dimensions: measuring in at 38.5mm in case diameter and 40mm lug-to-lug, the Group C Turbo Sport is compact, and sits fairly lightly on the wrist with a 11.4mm case thickness measurement. The case itself is anodized aluminum ...

A Majestic Journey Through Clocks & Watches Made for Royalty: King Philip II of Spain and the Rise of a Dynasty that Ruled by the Clock

From the imposing astronomical clocks of Tudor England to the exquisite pendant watches of Victorian Britain, timekeeping has long been a symbol of power, prestige, and technological marvel within Europe’s royal courts. This new series explores the fascinating evolution of clocks and watches crafted specifically for royalty, tracing how these intricate masterpieces reflected the tastes, ambitions, and innovations of monarchs. Through the lens of craftsmanship, artistry, and historical significance, we reveal how these royal timepieces marked the passage of dynasties and empires. King Philip II (1527–1598) inherited a globe-spanning empire from his father Charles V and, after 1580, also ruled Portugal. A devout champion of the Counter-Reformation, he centralised government, built the vast monastery-palace of San Lorenzo de El Escorial, and presided over Spain’s political zenith. His court prized scientific instruments and clocks as emblems of order and piety. Philip was part of the great Habsburg dynasty and the son of the Holy Roman emperor Charles V. From time to time, the emperor wrote Philip secret letters, impressing on him the high duties to which God had called him and warning him against trusting any of his advisers too much. Philip, a very dutiful son, took this advice to heart. During his reign the Spanish empire attained its greatest power, extent, and influence, though he failed to suppress the revolt of the Netherlands and lost the ‘Invincible Armada’...

Introducing: TAG Heuer Updates The Aquaracer Solargraph Professional And Debuts New 28mm Models Hodinkee

Introducing: TAG Heuer Updates The Aquaracer Solargraph Professional And Debuts New 28mm Models

What We Know The Aquaracer, first introduced in 2004, is the tough tool watch in the Tag Heuer lineup, and the Solargraph is one of the most recent extensions of the Aquaracer range, bringing quartz timekeeping and fuss-free solar power to the brand's generalist dive watch. Just in time for Summer (in this hemisphere), Tag Heuer has launched an extension of the Solargraph, offering new colorways and the option of a new, smaller case size.  In 2022, Tag Heuer began using La Joux-Perret's new solar-powered movements in some models that it labeled 'Solargraph' as part of an exclusive deal with the Swiss movement maker that saw the brand's owner, LVMH, later take a minority stake in LJP. Today, Tag Heuer is updating the Aquaracer line with four new 40mm models (spanning steel or titanium), as well as four 28mm-diameter steel-case versions for the first time. All the new models are powered by the Solargraph movement, underscoring the brand's commitment to new solar tech, which is also used in its relaunched Formula 1 watches. The new 40mm Aquaracer comes in both steel and titanium models and features an updated bezel with 'rider' tabs and grain-textured elements, as well as a sharper, finely brushed case construction with added fluted elements at 9 o'clock to better balance the crown guards at 6 o'clock. TAG says the handset has also been updated, and the bracelets are now easily interchangeable, with quick-release spring bar tabs, allowing for easy swapping to rubber or othe...

Hands On: Vacheron Constantin Overseas Dual Time “Cardinal Points”

The Vacheron Constantin (VC) Overseas Dual Time “Cardinal Points” was one of the most talked about releases of Watches & Wonders — despite being a somewhat predictable, incremental upgrade to an existing model. The response is indicative of strong product/market fit and the transformative power of colour and texture. Initial thoughts By all accounts, the Overseas Ultra-Thin ref. 2500V should have been the talk of the VC booth at Watches & Wonders. The copper-dialled platinum edition recalls one of the most sought-after models in the Overseas canon, and introduced a new micro-rotor movement that feels destined to be a big part of the brand’s movement strategy going forward. But it was the Overseas Dual Time that seemed to get people talking, despite its predictability and the fact that it’s a much more incremental update to an existing model. In my view, there are three reasons for this. First and foremost, it’s a perfectly targeted product, aimed at a well of unmet demand that has been simmering since the the titanium Dual Time was first teased seven years ago. The high/low contrast between the industrial-haute horlogerie build quality and the sporty aesthetic is inherently appealing. In some ways it feels like the perfect watch for locales like Sun Valley or Davos — the dual-time functionality is purpose-built for vacations (and economic forums) and the colours and textures will pair well with Mammut or Patagonia. Second, all four editions — named for the ...

A Majestic Journey Through Clocks & Watches Made for Royalty: Horological Renaissance In The Age Of Cosimo I de’ Medici

From the imposing astronomical clocks of Tudor England to the exquisite pendant watches of Victorian Britain, timekeeping has long been a symbol of power, prestige, and technological marvel within Europe’s royal courts. This new series explores the fascinating evolution of clocks and watches crafted specifically for royalty, tracing how these intricate masterpieces reflected the tastes, ambitions, and innovations of monarchs. Through the lens of craftsmanship, artistry, and historical significance, we reveal how these royal timepieces marked the passage of dynasties and empires. Cosimo I de’ Medici (1519–1574), the first Grand Duke of Tuscany, is remembered as a masterful statesman who unified Florence’s power. Yet behind his political authority lay a profound curiosity for the sciences, especially the study of the heavens and the measurement of time. The Medici family rose to power in Florence primarily through their wealth and strategic use of the Medici Bank, which became the largest and most powerful bank in Europe during the 15th century. They leveraged this financial power to influence Florentine politics, eventually establishing themselves as the de facto rulers of the city, although they maintained the appearance of a republic.  They used their wealth and influence to transform Florence into a leading capital of trading and a place for the greatest creators to work and develop incredible scientific instruments, such as the clock in the Cathedral of Santa...

Hands-On: The Citizen Eco-Drive Photon Keeps The Brand Ahead Of Their Light-Powered Competitors

A little over a month ago, Citizen celebrated the 50th anniversary of Eco-Drive with a massive bash in New York and a few new releases. The most striking, and unlike anything they had released in the past, was the new Photon. Aptly named, of course, because of the very particles—oh wait, or is it waves?—that power Eco-Drive movements. And before we get any further, these aren't solar watches like most watch movements that could be considered a "competitor" on the market. They are powered by any light around you, whether it's your office lights, home lights, or yes, the big bright ball in the sky that's starting to peek out more and more in New York. If you want to know more about Eco-Drive, our friend Griffin recently published a story about the technology (and its history) here. But this watch requires a slightly different history lesson. If you take a look at the dial below, you'll see it has a very unusual design. It's also out of the ordinary for Citizen, which prides itself on creating watches that can pass for any other watch aesthetically and don't require slits in the dial to transmit light (a problem other brands have struggled to engineer around). The new Citizen Eco-Drive Photons are two watches measuring 39.6mm by 9.9mm with integrated bracelets, all of which are made of Super Titanium with Duratect coating. One features a titanium carbide finish, while the other, with a two-tone dial and case band, uses a DLC finish. Each is limited to 5,000 pieces and ava...

Ressence Introduces First Proprietary Movement SJX Watches

Ressence Introduces First Proprietary Movement

Independent watchmaker Ressence unveils the Type 11, powered by a proprietary movement for the first time. The trailblazer of oil-filled mechanical modules, Ressence has so far relied on third-party base movements to power its eccentric creations. The Belgium-based watchmaker has finally taken the next step and developed its own calibre, dubbed the Ressence-Werk RW-01.  Initial thoughts  Ressence watches are instantly recognisable for their inventive and minimalist way of telling the time, using the patented Ressence Orbital Convex System (ROCS) to put a new spin on the classic time display. Using a clever arrangement of planetary gears powered by a base movement, Ressence has achieved an original functional design that remains unique to this day.  In terms of design, Ressence has an unmistakable, contemporary look, not unlike that of Apple. As a result, partnerships like those with industrial designer Marc Newson feel natural. The concept behind Ressence’s signature time display is the use of clear silicone-based oil which fills the hermetically sealed ROCS module to the crystal. The fluid medium cancels out total internal reflection, leading to the illusion that the turning disks sit right under the crystal itself. In this respect, Ressence dials can at times look like an OLED screen in a smartwatch. The Type 11 continues the signature streamlined minimalism of past Ressence models, but adopts a less complicated display. There are hours, minutes and seconds, arrange...

A Majestic Journey Through Clocks & Watches Made for Royalty: Henry VIII and the Birth of Royal Time

From the imposing astronomical clocks of Tudor England to the exquisite pendant watches of Victorian Britain, timekeeping has long been a symbol of power, prestige, and technological marvel within Europe’s royal courts. This new series explores the fascinating evolution of clocks and watches crafted specifically for royalty, tracing how these intricate masterpieces reflected the tastes, ambitions, and innovations of monarchs. Through the lens of craftsmanship, artistry, and historical significance, we reveal how these royal timepieces marked the passage of dynasties and empires. During Henry VIII’s reign (1509–1547), portable watches as we know them today had yet to emerge in significant numbers. Timekeeping was dominated by grand and stationary mechanisms, with tower clocks or ornate table pieces, serving both practical and symbolic purposes as a show of wealth and status. Watches, if present at all, were nascent and extremely rare. The first clocks and watches were expensive luxuries and only in the reach of royalty and landed gentry. There was, however, a sufficient demand for these items in the Tudor royal court which spread to a prosperous London. The beginnings of the horological industry were probably first initiated by King Henry VIII. During this period there was somewhat of a technical revolution, starting with the invention of the printing press which changed the way people received information. This filtered through to the court where there was a revoluti...

Felipe Pikullik Goes Fully In-House SJX Watches

Felipe Pikullik Goes Fully In-House

Berlin-based Felipe Pikullik presents his second in-house caliber inside the Sternenhimmel FPA1. The independent’s attempt at a refined workhorse-like movement comes in the form of the newly-developed caliber FPA1, designed to power a range of future creations.  Initial thoughts Mr Pikullik’s emergence into the crowded independent watchmaking scene was based on heavily skeletonised off-the-shelf movements. As he gained a reputation for deft finishing and began to consolidate his workshop, he slowly but surely transitioned toward in-house engineering. Starting with his own complication modules, the German watchmaker’s first truly in-house effort came with last year’s Moonphase II collection, which saw the launch of the calibre FPMP2.  The openworked construction featured a moon phase and 24-hour indicator but, while undoubtedly well-crafted, it arguably lacked a cohesive design language. Its distinctive architecture also made it unsuitable as the foundation for a wider range of pieces. In contrast, the updated Sternenhimmel (German for “starry sky”) features what the independent watchmaker describes as a cornerstone movement for future models. The FPA1 is consequently far more grounded and classical in construction, yet manages to avoid the trap of looking too much like any other artisanal time-only calibre. The ornate backside of the FPA1 caliber. This specific iteration of the Sternenhimmel design is decidedly more modern and technically-oriented, with a flo...

Citizen Marks 50 Years of Solar with Japanese Paper Dial SJX Watches
Citizen Marks 50 Years Mar 19, 2026

Citizen Marks 50 Years of Solar with Japanese Paper Dial

Citizen invented the first solar-powered analogue watch way back in 1976, and now it’s marking 50 years of its signature timepiece with “The Citizen” Eco-Drive 50th Anniversary. Five decades on Citizen’s solar technology is amongst the most advanced, and the anniversary edition is equipped with a movement that runs within five seconds a year, and will last 18 months on power save mode. But the dial, on the other hand, is traditional Japanese craft: it’s made of washi, a paper that’s dyed by hand, and translucent enough to allow solar charging. Initial thoughts The combination of washi, Super Titanium, and high-end quartz is a familiar one, with Citizen having applied it to past limited editions. Although Citizen is repeating the formula, this remains impressive from both a technology and materials perspective. The ultra-accurate A060 is one of the most sophisticated analogue quartz movements on the market, while Citizen’s proprietary hardened titanium, first polished by hand then hardened, is equally impressive. Tech aside, the anniversary edition stands out for the washi dial that adds a little bit of traditional Japanese craft to all of the cutting-edge tech in the watch. The dial is made of Japanese paper that’s dyed by hand with old school dyes obtained from plants. That said, this anniversary edition is still a relatively niche product for enthusiasts who appreciate high-end quartz technology packaged well. All of that tech and finishing comes at a pri...
