Best of Both Worlds for The Citizen’s 30th Anniversary SJX Watches
Citizen s 30th Anniversary Citizen Oct 14, 2025

Best of Both Worlds for The Citizen’s 30th Anniversary

Citizen marks 30 years of its upmarket The Citizen collection with a matching pair of limited-edition 30th anniversary watches with aquiline ivory dials. Representing the best of both worlds, the pair offer Citizen’s best calibres in mechanical and analogue quartz watchmaking: one contains the automatic Caliber 0200, while the other boasts the top of the line, feature-rich Eco-Drive A060. The Citizen Caliber 0200 30th Anniversary Initial Thoughts While little known outside Japan and certain enthusiast circles, the eagle-crested The Citizen watches are arguably the best Citizen has to offer, and also a tantalising value proposition. Both models are good in their own right, though the automatic is the winner here. The Calibre 0200 model is probably the best made-in-Japan integrated bracelet sports watch currently available, combining the impressive case and dial finishing we’ve come to expect from premium Japanese watches, and a significantly more upscale movement than the King Seiko Vanac or Credor Locomotive. The quartz model is appealing, The Citizen has plenty of other quartz offerings with the same movement but more interesting dials. The Citizen Eco-Drive 30th Anniversary Eco-Drive cal. A060 The conical bezel and flat lug chamfers of the Eco-Drive model are flat polished using a spinning tin-plate, creating a near distortion-free mirror finish. A Duratec “Platinum” treatment, with a hardness of over 1,000 Vickers, protects the case and bracelet, and also gives ...

Grand Seiko Introduces the SLGB005 “Violet Dawn” Worn & Wound
Grand Seiko Introduces Oct 1, 2025

Grand Seiko Introduces the SLGB005 “Violet Dawn”

Earlier this year at Watches & Wonders, Grand Seiko revealed the SLBG003, which turned out to be one of the most impressive watches of the whole show. Housing the new 9RB2 Spring Drive caliber, the UFA (Ultra-Fine Accuracy) movement is certified to an almost incomprehensible +/- 20 seconds per year, or roughly 3 seconds per month. That makes it, according to Grand Seiko, the most accurate movement powered by a mainspring. It’s a truly impressive horological achievement.  Of course, as soon as a brand like Grand Seiko introduces an entirely new platform like the UFA, enthusiasts are on pins and needles waiting to see what comes next. It’s not that we can’t appreciate what we have in front of us, but particularly with Grand Seiko, we know that variants are coming in the form of new dial options and case materials. If you had asked me in the Spring when we’d see the first derivation on the UFA line, I probably wouldn’t have expected to see a new watch so soon, but last week Grand Seiko dropped the Evolution 9 Spring Drive UFA SLGB005, nicknamed the “Violet Dawn” for its deep purple dial. It’s always interesting to see what new watches in a new sub-collection come to pass, not just for what it says about where the line is going, but perhaps where it’s not.  The SLGB005, like its predecessor, is what we’d probably call a small-medium size by today’s standards, measuring a conservative 37mm. Unlike the titanium SLBG003, however, this watch is clad in a st...

Trilobe Takes Up the Mantle of French Watchmaking with the Trente-Deux SJX Watches

Trilobe Takes Up the Mantle of French Watchmaking with the Trente-Deux

Best known for its signature time display comprised of three off-center discs, Trilobe has introduced its first sport watch, the Trente-Deux. It’s yet another sports watch with an integrated bracelet, but the Trente-Deux is more notable for being the debut platform for the new X-Nihilo caliber, which for movement geeks will overshadow the launch of the new collection itself. The X-Nihilo is a relatively simple automatic caliber, and many of its components are produced in Trilobe’s own newly established CNC workshop near the French capital. It remains to be seen whether this domestic manufacturing initiative will prove viable long-term; the recent past is full of false starts aimed at rebuilding the French watchmaking industry. Initial thoughts I admit a certain fascination for watches without hands, that indicate the time with jumping windows, wandering displays, and revolving discs. The Trente-Deux, like the brand’s other watches, is an example of the latter. The hour is read at the top of the dial, using the logo as a pointer. The minutes slip by through a window in the dial, and the seconds disc rotates around a central hub embellished with stamped Clous de Paris. The asymmetrical layout is visually compelling and results in a pleasing amount of negative space that somehow doesn’t feel empty. This might be due to the sunray pattern, which emanates outward from the center of the seconds disc. In terms of colour, grey and navy blue are safe, pragmatic choices tha...

Valjoux 7750: The Story Of The World's Most Famous Chronograph Teddy Baldassarre

Valjoux 7750: The Story Of The World's Most Famous Chronograph

The Valjoux 7750 chronograph caliber has been a mainstay of the Swiss watch industry for more than 50 years, finding its way into hundreds of watch models, under many dozens of names, and providing the technical base for numerous high complications over the years. Why is it so ubiquitous and still such an enduring presence in the watch world today? Here is a brief history of the "workhorse" mechanism that became the world's most famous and familiar chronograph movement.   Valjoux 7750 Roots: The Vallée de Joux   Sunset over the Vallée de Joux In actuality, the origins of the Valjoux 7750 go back much longer than the half-century it has actually been on the market. The company that came to be called  “Valjoux” started up at the very beginning of the 20th century, taking its original name, Reymond Frères SA, from its founders, brothers John and Charles Reymond. The company, which specialized in making mechanical chronograph movements for military and sport-oriented timekeepers, changed its name in 1929 to Valjoux - a shortened reference to the scenic Vallée de Joux in Switzerland, where it and many of its client watchmakers were located. The firm’s most successful and historically impactful creations included the manually wound, column-wheel-driven, monopusher Caliber 22, in 1914, and its even more significant successor, the smaller, longer-lived Caliber 23, in 1916. In honor of the founding brothers' surname, Valjoux movements were inscribed with a shield em...

Omega’s Small-But-Mighty Movement in the Aqua Terra 30 mm SJX Watches
Omega s Small-But-Mighty Movement Jun 25, 2025

Omega’s Small-But-Mighty Movement in the Aqua Terra 30 mm

Omega’s latest Aqua Terra is a competent women’s watch with a brand-new calibre that is both compact and proficient. Equipped with the new cal. 8750/8751, the Aqua Terra 150M 30 mm launches with a healthy mix of metal variations and dials across 12 models that will surely expand in time. Initial Thoughts Despite scarce coverage in watch media, watches made for, and marketed to women are very important to the industry. And, women have rewarded brands that put in the effort with enormous success. The Lady-Datejust, for instance, is often rumored to be Rolex’s highest volume model. While Omega offered an Aqua Terra 30 mm in the past, the Constellation has arguably the brand’s champion in the segment for the last few years. The new Aqua Terra 30 mm might look similar to its predecessor, but it stands out for the new cal. 8750/8751 that is a Master Chronometer-certified movement. Building a movement that can consistently meet Master Chronometer standards, while being small and thin, is an achievement on its own. All else being equal, larger movements perform better than smaller ones; the difference is significant enough that the ISO 3159 chronometer standard that form the COSC testing standards has less stringent requirements for movements 20 mm and under. Options Omega’s watches are often, and fairly, criticized for being unnecessarily thick, but that isn’t the case here, thanks in part to the new caliber. All steel and two-tone models are 10.6 mm tall (10.7 mm for...
