At Watches & Wonders 2026, Zenith evolves its best-selling Chronomaster Sport with a fully skeletonized sapphire dial and a redesigned clasp, while continuing to expand its ambitious George F. Jaquot dress watch program. Tim Mosso goes hands-on with the full lineup.

The Chronomaster Sport Skeleton is the headline — for the first time, the brand's best-selling model gets an open-worked dial. Not a standard skeleton: the dial itself is a smoked, gradient-tinted sapphire that darkens toward the edges where the hour indices sit, maintaining legibility despite full visibility of the El Primero Caliber 3600 movement beneath. Available in black ceramic bezel, green ceramic bezel, and rose gold with integrated rubber strap and double-deploying clasp. All references are 41mm, 100m water resistant, 60-hour power reserve, non-limited.

The new clasp is a significant upgrade and available separately for all existing Chronomaster Sport bracelet owners. A cam action releases the entire clasp in one motion — no double-snap. 10mm of on-wrist micro-adjustment in 2.5mm increments. Ceramic spring-loaded pin snaps internally prevent wear on the clamshell mechanism. Patented.

A 50-piece limited edition Chronomaster Sport in steel and gold with Tahitian black mother-of-pearl dial rounds out the sports collection — the polychromatic, kaleidoscopic quality of the darker pearl gives the dial a depth white MOP cannot match.

A 10-piece diamond-set edition with 5 carats of VVS diamonds on the bezel is already sold out.

The George F. Jaquot continues Zenith's return to Caliber 135 — a movement from 1949, dormant for 63 years until its revival in 2025, and one of the most awarded chronometry calibers in watchmaking history. The 2026 edition arrives in a tantalum case for the first time — just 20 pieces, boutique exclusive, available from September. The three-part dial combines black onyx, baguette diamond indices, and black mother-of-pearl on the sub-seconds. The caseback decoration is upgraded from last year, now featuring Côtes de Genève and engine-turned perlage alongside the distinctive brick-cut engraving referencing Zenith's Le Locle manufacture. 72-hour power reserve, chronometer certified, stop seconds.

The 161st anniversary piece — one more than last year's 160 — arrives in yellow gold with Bloodstone Jasper dial and green mother-of-pearl sub-seconds. A matching yellow gold bracelet is available made to order. Both new Jaquot references feature 39mm cases and the same fully in-house Caliber 135.
