Watches & Wonders: Zenith Expands the Chronomaster Sport Line with New Skeleton References, Plus a Two-Tone Version with MOP Dial, and a New Micro-Adjustable Clasp Worn & Wound

Watches & Wonders: Zenith Expands the Chronomaster Sport Line with New Skeleton References, Plus a Two-Tone Version with MOP Dial, and a New Micro-Adjustable Clasp

Zenith has released five new references under the Chronomaster Sport umbrella, most notably with four skeletonized versions of the design, as well as a dressier two-tone option. To understand the new skeletonized editions, it’s probably best to start at the beginning. When Zenith introduced the El Primero in 1969, it launched what is widely regarded as the world’s first automatic, integrated high-frequency chronograph caliber, a movement that has remained central to the brand’s identity ever since. The Chronomaster collection has long carried that legacy forward, and with this new series of skeletonized watches, Zenith brings that movement further to the forefront. All of the skeleton models run on the El Primero 3600SK, the openworked version of Zenith’s high-frequency automatic chronograph. Like the standard El Primero 3600, it beats at 5 Hz, which allows the central chronograph hand to complete one full rotation every 10 seconds and display 1/10th of a second directly off the bezel. The movement also offers a 60-hour power reserve, while the open dial and caseback give a clear view of the column wheel, horizontal clutch, and star-shaped rotor. All come in the now familiar 41mm Chronomaster Sport case. In regards to the design of the Chronomaster Sport Skeleton models, the biggest visual shift comes from the opened-up dial. The collection includes two stainless steel versions: one with a black ceramic bezel and the signature grey, anthracite, and blue tri-color c...

Ressence Debuts the Type 11, with the All New In-House RW-01 Movement

For as long as we’ve talked about Ressence, part of the discussion has always been about how clever they are for producing such an ingenious and unique system for time telling, all built on top of a standard, off-the-shelf ETA movement. Their patented ROCS module, which displays the time via a series of rotating discs rather than traditional hands, is a complicated piece of engineering that has always lived alongside a caliber that is rather ordinary. For me, and many others, this was always part of the charm of a Ressence watch, and underscored the idea that watchmaking is a broad discipline and that with some creativity even a simple ETA movement can be turned into something extraordinary.  That changes a little today with the introduction of the Ressence Type 11, featuring the all new RW-01 movement, the first in-house designed Ressence movement. Designed specifically to power the ROCS, the RW-01 is an integrated, automatic caliber that appears to be an improvement in just about every way over previous movements found in Ressence watches.  First and perhaps most notably, this movement has a 60 hour power reserve, which can be monitored on the dial via ceramic micro balls. For years, Ressence watches have featured power reserves that topped out at slightly less than the ETA movements they were based on due to the demands of running the ROCS module. But the RW-01 was designed from the ground up to work with ROCS, eliminating many of the compromises made with previous ...

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...

Hands-On With The Rado Anatom Automatic Skeleton

It’s time for a short confession: generally, I am not the biggest fan of skeletonized watches. While I greatly appreciate the possibility of witnessing a caliber in action, I much prefer to see it in action through a sapphire display in the case back. It’s purely an aesthetic thing because, as a design fanatic, I […] Visit Hands-On With The Rado Anatom Automatic Skeleton to read the full article.
