Trilobe Takes Up the Mantle of French Watchmaking with the Trente-Deux SJX Watches
Trilobe Sep 17, 2025

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...

Hands-On Review With The New Grand Seiko Spring Drive U.F.A WatchAdvice

Hands-On Review With The New Grand Seiko Spring Drive U.F.A

Grand Seiko’s Spring Drive U.F.A (SLGB003) sets a new benchmark in mechanical watchmaking with an astonishing ±20 seconds per year accuracy. Wrapped in a new slimmer Evolution 9 case and finished with a dial inspired by winter in Shinshu, it’s a masterclass in subtle innovation and timeless elegance. What We Love The Calibre 9RB2 delivers an incredible +/- 20 seconds per year, redefining what is possible from a mainspring-powered mechanical movement The new 37mm case size makes the timepiece highly wearable for a wide range of wrist sizes. The beautifully textured dial captures Grand Seiko’s unique blend of craftsmanship and storytelling. What We Don’t While very comfortable, the standard three-link bracelet feels a little too plain for a release of this calibre. For a groundbreaking caliber, the caseback view feels a little subdued. For such a significant release, the design feels a little too in line with previous Evolution 9 models. Overall Rating: 9.25 / 10 Value for Money: 9.5/10 Wearability: 9.5/10 Design: 9/10 Build Quality: 9/10 Grand Seiko was first established in 1960 as a sister brand to Seiko, created to combat the Swiss watchmakers and their high-end luxury timepieces. While Seiko made affordable everyday timepieces, It was Grand Seiko’s role to create unique, innovative pieces that would cater to the luxury and high-end watchmaking market. Among the many different innovations and stunning dial aesthetics, one key aspect that truly makes Grand S...

J.N. Shapiro Debuts Entry-Level Infinity Series Pure SJX Watches
Hamilton shut down Jun 4, 2025

J.N. Shapiro Debuts Entry-Level Infinity Series Pure

J.N. Shapiro’s Infinity Series Pure is a new entry point into the American brand. This follows the top-of-the-line Resurgence, the most American-made mechanical wristwatch built since Hamilton shut down in the 1960s. This new model focuses purely on the dial and hands, which are excellent, while trusting Swiss suppliers with ancillary details like the case and caliber. The result is a much more accessible, though less impressive, watch than J.N. Shapiro’s usual fare. Initial Thoughts When the original Infinity line was discontinued in 2023, it left the brand without an entry-level watch, and the company put all of its efforts behind the ambitious Resurgence project. Now that things have settled down, the team once again has the bandwidth to support a second model. The Infinity Series Pure uses an off-the-shelf La Joux-Perret (LJP) movement. While a good, slim movement with an extended power reserve, the LJP F200/7380 isn’t particularly premium, and a downgrade from the UWD cal. 33.1 used in previous infinity models. For example, Ralph Lauren uses the LJP movement in its Vintage 67 line priced at around US$3,000. The case is also outsourced, likely to a Swiss manufacturer, through the Alternative Horological Alliance (AHA), a consortium of independent brands that J.N. Shapiro helped found. This focuses all of Shapiro’s attention on the dial and hands, though both are significantly less complex than on the Resurgence. At US$26,000 the Infinity Series Pure is about a ...

Hands On: Grand Seiko Spring Drive Chronograph SBGC275

Twenty-twenty four marks the 20th anniversary of Grand Seiko’s 9R Spring Drive movement platform, an occasion the brand has chosen to mark with a range of anniversary editions including the Grand Seiko Caliber 9R 20th Anniversary SBGC275. A large, richly detailed watch with a captivating dial, the SBGC275 is robust, interesting, and capable of nearly anything, short of fitting under a short cuff. Initial thoughts At first glance, the SBGC275 looks like just a Spring Drive chronograph with a red dial. But a closer look reveals a highly nuanced colour that changes from red to orange depending on the angle – the result of a proprietary dial coating technique. At 44.5 mm in diameter and nearly 17 mm thick, the SBGC275 is unapologetically big and bold. That said, the watch feels smaller than it is thanks to the use of titanium for the case and bracelet, and the unusually wide 23 mm lug width helps reduce the visual size. This latter dimension may limit the options for aftermarket straps, but since most owners will likely stick with the bracelet, this concern is largely academic. The watch is powered by an upgraded version of the familiar cal. 9R86 Spring Drive chronograph GMT movement, which made its debut in 2007. But eagle-eyed movement geeks will notice the SBGC275 is equipped with the fine-tuned cal. 9R96 first seen in 2017, which was also used in the Nissan GT-R 50th Anniversary edition. In many ways, the SBGC275 captures Grand Seiko’s strengths and weaknesses. The b...
