Zenith High-Frequency Performance and Chronometric Legacy
Zenith has unveiled new models at Watches and Wonders 2026, showcasing both its high-frequency El Primero movements and the observatory-grade Calibre 135. The releases include variations of the Chronomaster Sport and the G.F.J. collection, presented in materials ranging from two-tone steel and gold to tantalum and yellow gold.
- Chronomaster Sport Two-Tone: Limited to 50 pieces
- Chronomaster Sport Skeleton: Limited to 10 pieces (diamond-set rose gold)
- G.F.J. Tantalum Limited Edition: Limited to 20 pieces
- G.F.J. Yellow Gold with Bloodstone: Limited to 161 pieces
The Chronomaster Sport Two-Tone features a 41mm stainless steel case with an 18-carat rose gold bezel, crown, and pushers, and a mother-of-pearl dial with gold-plated markers.
The El Primero 3600 movement in the Chronomaster Sport operates at 36,000 VpH (5 Hz) and allows for 1/10th of a second indication directly on the bezel.
The Chronomaster Sport Skeleton in 18-carat rose gold is set with 52 VVS baguette-cut diamonds totaling approximately 5.00 carats, with an openworked architecture revealing the El Primero 3600 SK movement through a smoked black gradient sapphire dial.
The G.F.J. Tantalum Limited Edition, named after Zenith’s founder, houses the Calibre 135 observatory chronometer movement in a 39.15mm tantalum case, featuring a brick-pattern guilloché outer ring, onyx center, and mother-of-pearl small-seconds counter.
Both variants of the G.F.J. collection are regulated to -2/+2 seconds per day and beat at a classic 18,000 vph.
The G.F.J. Yellow Gold with Bloodstone model features a striking jasper “bloodstone” dial center, surrounded by a brick guilloché outer ring and a mother-of-pearl small-seconds subdial, powered by the COSC-certified Calibre 135.
The Calibre 135 movement in the G.F.J. Yellow Gold with Bloodstone is finished with Ruthenium Côtes de Genève and has a 72-hour power reserve.
