Omega Speedmaster MK40 Review: A Colorful Cult Classic Teddy Baldassarre

Omega Speedmaster MK40 Review: A Colorful Cult Classic

When you think of the Omega Speedmaster, the first thing that comes to mind is likely the brand’s golden child, the Speedmaster Moonwatch Professional. It’s a modern grail with its NASA connection, and its intertwined history with the Moon landing and space exploration is its calling card. But today, we’re looking at a different Speedmaster that has been eschewed from Omega’s current lineup. One that’s a little more playful, a little more unconventional, than the brand’s well-established Moonwatch Professional formula: the Speedmaster Mk40. Down below, I’ll be breaking down the history, context, and all the aesthetic oddities of the watch, all of which work together to create one of the most compelling non-Moonwatch Speedmasters of all time, in my humble opinion.  [toc-section heading="Some Speedmaster Context"]  Image: S.Song From first glance, the Speedmaster Mk40 that made its debut in the ‘90s defies all the utilitarian, tool-watch-oriented austerity that is the key DNA of the Moonwatch Professional, from its functionality to its experimentation with color, shapes, and typography. But the Mk40 is part of a short-lived and often forgotten legacy of Omega’s experimentation with the Speedmaster formula, before things were so rigidly codified as they are today. It is also important to note that the moniker “Mk40” itself is a completely enthusiast-driven nickname, which Omega itself has never officially used (the brand denotes the different models wi...

Annual Calendars Are Goldilocks Complications: Not Too Hot, Not Too Cold, Just Right

Sometimes perpetual calendars are too complicated but a simple calendar just doesn't cut it anymore because nearly half the months have less than 31 days, making it five adjustments a year too many for some. But don’t fret, there is a middle ground between the most basic calendar watches and complex perpetual calendars: the annual calendar automatically adjusts for each month with 30 or 31 days, meaning just one adjustment per year for the owner in February. Here's a brief history of the complication.

Introducing: The Ming 21.01 “Project 21” In Tantalum

As a materials engineer, I get excited whenever a watchmaker uses an atypical material. Over the last decade, carbon and ceramics have become more prevalent for watch cases. However, aside from new gold alloys, it has been relatively quiet on the metals front. Using tantalum isn’t new, but it’s so uncommon that it deserves attention […] Visit Introducing: The Ming 21.01 “Project 21” In Tantalum to read the full article.

Grand Seiko Recreates 45GS with Calibre 9SA4 SJX Watches
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 Introduces the SLGW002 and SLGW003 “Birch Bark” SJX Watches
Grand Seiko Introduces Apr 12, 2024

Grand Seiko Introduces the SLGW002 and SLGW003 “Birch Bark”

Grand Seiko has introduced the Evolution 9 “Birch Bark” SLGW002 and SLGW003, in rose gold and “brilliant hard titanium” respectively. Named after the dial pattern, the “Birch Bark” is powered by a new manually-wound, high-beat caliber that features the brand’s proprietary dual-impulse escapement. The only completely new model introduced by Grand Seiko at Watches & Wonder this year, the new references introduce a new, notably slimmer aesthetic to the brand’s Evolution 9 collection.  Initial thoughts Grand Seiko has earned a devoted following in recent years, but collectors have been asking for slimmer options for some time; this release proves the brand is listening. While there’s nothing revolutionary about it, the watch has been nipped and tucked in all the right areas, getting the case down to 38.6 mm in diameter and just under 10 mm in thickness.  Compared to the most similar existing watch in the catalog, the Spring Drive SLGA009 “White Birch” launched two years ago, the new Evolution 9 feature a new movement, a thinner case, slimmer dial markers, and a horizontal interpretation of the brand’s signature white birch-inspired dial texture. The slimmer profile is made possible thanks to the new 9SA4 movement, which is essentially a 9SA5 without automatic winding. This makes it the first manually wound caliber from Grand Seiko’s latest generation of mechanical movements, and also the first to be available without a date function. Perhaps the onl...

Patek Philippe’s Celestial Ref. 6105G Blasts Off

Patek Philippe updates its star chart “Grand Complication” for the third time with the Celestial Sunrise Sunset Ref. 6105G. The ref. 6105G adds the time of sunrise and sunset – cleverly integrated into the date scale – and a daring new design with a formidable, space-age lug-less case in white gold that’s 47 mm across. The ref. 6105G also introduces a novel way to account for the transition between summer and winter time, adding a corrector that shifts the sunrise and sunset scales, solving a significant shortcoming of astronomical watches for users in Europe and the Americas. Initial thoughts I’ve long thought that Patek Philippe’s greatest strength, other than its massive industrial investments, was its remarkable design diversity. Today brands seem to pursue a unified design language across all of their watches. And while this result is a strong visual identity for the brand, it is extremely limiting. Patek Philippe has no such limits, and the brand has about two dozen different case styles in the current collection, and hundreds in its back catalog. While this leads to its fair share of design misses, at least to my sensibilities, it can also lead to striking successes. I’m sure many will disagree, but I see the new Celestial as the latter. A wristwatch with the time of sunrise and sunset is long overdue from Patek Philippe, and this watch adds the ability to adjust those indications to account for daylight savings time. This addresses the complication...

Patek Philippe Marks 50th Years of The Nautilus with Two Hands and a Pocket Watch SJX Watches

Patek Philippe Marks 50th Years of The Nautilus with Two Hands and a Pocket Watch

Patek Philippe celebrates the semicentennial of its coveted sports watch with the 50th Anniversary Nautilus Collection, a trio of two hand precious metal watches in white gold and platinum – and an unexpected pocket watch desk clock. The deletion of the seconds hand is a return to the line’s aesthetic roots, also demonstrated by a new 38 mm case size, very close to that of the original. But, it remains on the precious metal path Patek Philippe began in 2021 when it axed the steel ref. 5711. Initial Thoughts These anniversary editions are the truest to the original Nautilus that we’ve seen in recent memory. The sans seconds ref. 3700/1A, launched in 1976, was powered by the JLC 920-based cal. 28-355C, which the calibre 240 was meant to replace. While Audemars Piguet stuck to the two hands plug date format with the Royal Oak Jumbo, Patek Philippe migrated the Nautilus to its new sweep-seconds platform. I believe something was lost when Patek Philippe added a sweep seconds hand to the Nautilus, though understandable from a business perspective given that watches with seconds hands generally have broader appeal than those without. That is recovered here, and the deletion of the calendar sets it apart from the original enough to not be a “reissue”. A smaller 38 mm Nautilus, with better proportions than the existing Ladies models, in also appreciated. The 38 mm platinum ref. 5610/1P-001. It is a shame then that the return of a two hand Nautilus is to be a fleeting one,...

Vacheron Constantin Facelifts the Iconic American 1921 SJX Watches
Vacheron Constantin Facelifts Apr 13, 2026

Vacheron Constantin Facelifts the Iconic American 1921

Vacheron Constantin has gently updated one of its most distinctive time-only watches, the Historiques American 1921. Now kitted out with a silver grained dial, the 1921 retains its characteristic dial layout, along with blue Breguet numerals and hands. Like its predecessor, the new 1921 is also available in two sizes, 36.5 mm and 40 mm, but only in pink gold for now. Initial thoughts Ordinarily, cosmetic variations would not be that interesting, but the 1921 has not been iterated upon too often, despite being almost 20 years old. In fact, the 1921 is a fixture in the VC catalogue, yet has varied little given its tenure. As a result, the facelifted model is appealing and also arrives in a timely manner. Though the changes are subtle, namely to the dial texture plus hand and numeral colour, they give the dial a little more life. The updates also make the watch feel a little more modern, but the result still sits comfortably with the historical design. A driver’s watch Sometimes known as a “driver’s watch” for its off-the-vertical dial layout, the 1921 was modelled a small number of watches made by VC in 1919 and subsequent years. The unusual dial alignment was reputedly to improve legibility while driving, or while preaching at the pulpit for one of the owners of the 1920s originals was an American clergyman. The latest version retains the same design and layout as past iterations, with the dial 45 degrees off the vertical and the crown at two o’clock. Instead of a...

Raymond Weil Marks 50 Years with 50 Year-Old Valjoux 23

Building on the success of its retro wristwatch, Raymond Weil is marking its 50th anniversary with the Millesime “The Fifty”. While it retains the familiar “sector” dial of the Millesime, the Fifty boasts upgraded mechanics in the form of a “new old stock” Valjoux 236 dating from 1976, the year of brand’s founding by the eponymous Raymond Weil. The Fifty combines the vintage movement with a thoughtful design that includes an appropriately sized 37 mm case – steel but with a white gold bezel no less – and novel texturing on the “sector” dial. Notably, the Fifty is also priced well at under CHF9,000. Initial thoughts The base model Millesime is good for what it is, combining an appealing design with an affordable price. The Fifty is more expensive, but arguably even better, because it still has an appealing aesthetic, but now with an excellent movement and a fair price. Watches powered by a vintage Valjoux 23 usually cost more – Singer Reimagined’s equivalent costs almost double – making the Fifty a good value proposition. And it certainly doesn’t hurt that it evokes the Patek Philippe ref. 1436 “Tasti Tondi”. But it’s more than just accessible; the design of the basic Millesime has been elaborated on in a concise and logical manner. The result is a watch that clearly resembles the standard model, but with finer details, including the linear patterning on the dial centre. I disagree with some minor details, like the luminous hands that don...

IWC Portugieser Chronograph Ceratanium Review Teddy Baldassarre
IWC Feb 26, 2026

IWC Portugieser Chronograph Ceratanium Review

In 2017, IWC introduced a proprietary alloy called Ceratanium, or ceramized titanium, a hard, lightweight material that combined the best of ceramic and titanium. Oh, and it happened to look pretty cool as well. The material has been used sparingly in the intervening years, largely appearing across the brand’s sport-watch portfolio, from the Pilot to the Aquatimer collections. This week, Ceratanium is making its first appearance in the Portugieser collection with a new, limited-edition 41mm chronograph featuring a Ceratanium case affixed to a black rubber strap. In an effort to drive the point home, the rest of the watch is fully murdered out making the IWC Portugieser Chronograph Ceratanium a decidedly sporty take on this otherwise dressier collection. [toc-section heading="What's New"] The new watch is the Portugieser Chronograph Ceratanium, and it turns the classic chronograph layout on its head by rendering every detail in shades of black (insert Henry Ford quote here). The Portugieser is a historic watch with roots that date back to the late 1930s, and its modern aesthetic is largely referential to that history. That underlying design remains intact here, with a large, open dial hosting Arabic numerals at each hour, and a set of leaf hands tracking the time against them. The two subdials are arranged vertically, retaining a symmetric layout that recalls the original time-only references that had subsidiary seconds located at 6 o’clock.  Using Ceratanium (which ha...

Orient Star’s M34 F8 Skeleton is Space-Age Tech SJX Watches

Orient Star’s M34 F8 Skeleton is Space-Age Tech

Orient Star marks a milestone with the M34 F8 Skeleton Hand Winding 75th Anniversary, combining the brand’s technically adept, manually wound skeleton calibre with a novel, laser-engraved meteorite pattern in a maximalist open-worked package. The M34 F8 Skeleton also stands out for the tech inside the mechanical movement: proprietary silicon escape wheel with a novel, optimistic geometry that helps the M34 punch above its weight from a technical standpoint. Initial thoughts Last year, Orient Star launched the brand’s first manually wound moon phase – made of mother-of-pearl no less – for fans of understated, formal watches. Now celebrating its 75th anniversary, Orient Star has cast aside restraint to mark the occasion with something for a more maximalist breed of collector. The new skeleton has a blacked-out case and bracelet and an open-worked version of its top-of-the-line F8 movement. Notably, the movement plates are bridges, which are exposed front and back, are decorated with a laser-etched meteorite motif that is impressively detailed. This skeletonised anniversary limited edition also features the latest technology from its powerhouse parent company Seiko Epson, including a silicon escape wheel with an especially advantageous design. While silicon is increasingly common in the watch industry, it is used primarily for hairsprings. This puts Orient on the list of short brands with a proprietary silicon escape wheel that includes blue-chip names like Patek Phil...

Hands On: Audemars Piguet Royal Oak Perpetual Calendar Openworked SJX Watches

Hands On: Audemars Piguet Royal Oak Perpetual Calendar Openworked

Audemars Piguet (AP) has updated the coveted Royal Oak Perpetual Calendar Openworked, which makes its debut on the next-generation perpetual calendar platform that debuted last year. The new calibre allows for individual adjustment of each calendar indication using just the crown – no stylus (or toothpick) necessary. The first outing for the skeletonised version of this class-leading perpetual calendar is in titanium, with mirror polished accents in scratch-resistant Palladium BMG and pops of rose gold on the dial and case back, though more colourways are sure to come in due time. Initial thoughts The latest generation of the Royal Oak Perpetual Calendar is arguably AP’s strongest product. It is heir to the archetypal integrated bracelet perpetual calendar sports watch, which, until recently, was held back to some extent by what had become a dated movement. In fairness, the same can be said of its obvious competitors from Patek Philippe and Vacheron Constantin. That changed in 2025 when the Royal Oak Perpetual Calendar was upgraded with the AP’s latest perpetual calendar movement, a significant release befitting the brand’s 150th anniversary year. The calibre 7138 introduced individual correction of the date, day, month, and moon phase using only the crown, allowing for quick adjustment without tools and with greater flexibility, and support for more indications, than existing solutions. And while we already understood the movement’s clever functionality, it rema...
