Introducing: The Krayon Parhelion, A Maximalist Take On The Brand’s Anywhere Watch

What We Know Pretty much anything that independent watch brand Krayon produces feels like it rests solidly in the if-you-know-you-know realm of exquisitely engineered high-end complications. The brand's focused catalog contains variations on three main complications—the universal sunrise and sunset calculator that is the Everywhere, the watchmaker-adjustable sunrise and sunset-indicating caliber that is the Anywhere, and the most recently introduced weekday and weekend pointer date display in the Anyday. Sure, Krayon's recent Pac-Man collaboration in a limited run of Anywhere watches might feel like an odd one out, but most of the examples I've seen on the wrists of collectors have all flown well under the radar with tastefully measured executions. But if you've ever wondered what a Krayon would look like with a touch—scratch that, a lot—of bling, well, the new Parhelion might just do the trick. It's hard to mistake this new watch for anything else in the catalog thanks to the sheer number of baguette-cut sapphires set across the entire watch—159 of them, to be exact. To house this number of gemstones, the case is 42mm in diameter, made from an alloy of white gold with a high percentage of palladium for a very white hue to match the brightness of the stones. Thickness, given the complication, is impressive at 9.5mm. When I first saw a prototype of the Parhelion a few months ago, only the bezel was inlaid with sapphires, in a stunning gradient from white to blue. Bu...

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...

Grand Seiko Just Released a Collector’s Dream Watch! Worn & Wound
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...
