Zenith Chronomaster Sport Stainless Steel - Rose Gold / MOP / Bracelet Ref. 51.3102.3600/01.M3100

The Zenith Chronomaster Sport 51.3102.3600/01.M3100 debuted in 2026 as a limited edition of 50 pieces in stainless steel and 18-carat rose gold, combining the standard Chronomaster Sport case architecture with a mother-of-pearl dial and a two-tone bracelet. In this reference, the Chronomaster Sport is not skeletonized and remains powered by the closed-dial El Primero 3600, while the case, bracelet, and bezel introduce a different material configuration from the steel versions. Its case measures 41mm in diameter and 13.6mm in thickness, with a lug-to-lug distance of 47mm. The construction combines stainless steel with 18-carat rose gold, including the bezel, crown, and pushers, and is finished with alternating brushed and polished surfaces. The bezel is graduated for the reading of elapsed tenths of a second, in line with the El Primero 3600’s 10-second chronograph indication. The watch is fitted with a domed sapphire crystal with anti-reflective treatment on both sides, a transparent sapphire case back, and is water-resistant to 10 ATM. The dial is executed in mother-of-pearl and retains the Chronomaster line’s overlapping 3-6-9 counters in three different colours. Gold-plated faceted hour markers are coated with Super-LumiNova C1, while the gold-plated hands are coated with beige Super-LumiNova C1. A date aperture is positioned at 4:30. Compared with the skeletonized Chronomaster Sport Skeleton models, this reference keeps the movement concealed beneath a solid dial, with the mother-of-pearl surface becoming the main visual distinction. Inside is the El Primero 3600, an automatic column-wheel chronograph movement operating at 36,000 vibrations per hour, or 5Hz, with a power reserve of approximately 60 hours. It consists of 311 components and 35 jewels, and displays central hours and minutes, small seconds at 9 o’clock, a date at 4:30, and a 1/10th of a second chronograph. In this layout, the central chronograph hand completes one full rotation in 10 seconds, accompanied by a 60-minute counter at 6 o’clock and a 60-second counter at 3 o’clock. The movement also incorporates a stop-seconds mechanism and a star-shaped oscillating weight with satined finishings. This reference is fitted with a stainless steel and 18-carat rose gold bracelet with folding clasp and is also supplied with an additional black rubber strap with folding clasp.
