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 counters, and another with a green ceramic bezel paired with grey-toned counters. Next in the collection is an 18-carat rose gold version with a black ceramic bezel. And finally in the Skeleton collection is a diamond-studded reference with a gold bracelet and 50 baguette-cut diamonds around the bezel.
Zenith is also using the steel skeleton models to introduce a new patented folding clasp with on-the-fly micro-adjustment. The clasp can be adjusted directly on the wrist in 2.5 mm increments across a total range of 10 mm, and incorporates a locking system built with ceramic ball components. According to Zenith, its development took three years and involved 41 components, with the clasp expected to roll out across additional Chronomaster Sport references over time.
Alongside the skeleton pieces, Zenith is also adding a two-tone Chronomaster Sport, pairing a steel case with a rose gold bezel, crown, and pushers, while also utilizing mother-of-pearl for the dial. By layering on the luxury, Zenith is able to show the adaptability of the Chronomaster design and expand the definition of a dress watch within this broader line-up.
The new Chronomaster Sport Skeleton models have a price tag of $16,700 in steel, $31,500 in rose gold, and an eye-watering $111,000 for the 10-piece diamond-set edition. For the two-tone Chronomaster Sport, Zenith has priced this one at $20,100 and limited it to just 50 pieces. Zenith
