Released in 2026, the Zenith Chronomaster Sport 51.3102.3600/01.M3100 is a limited edition, limited to just 50 units, that exquisitely blends stainless steel with 18-carat rose gold. It features the classic case design seen in the Chronomaster Sport series, but what makes this model unique is its striking mother-of-pearl dial and a two-tone bracelet. Unlike the skeletonized versions in the collection, this model retains a solid dial powered by the El Primero 3600, which is fully enclosed.

With a case diameter of 41mm and a thickness of 13.6mm, the watch presents a lug-to-lug measurement of 47mm. Notable for its dual-material structure, this piece incorporates rose gold elements on the bezel, crown, and pushers, all masterfully finished with a combination of brushed and polished surfaces. The graduated bezel allows for precise timing of elapsed tenths of a second, in alignment with the chronograph's 10-second functionality. Protecting the dial is a domed sapphire crystal with anti-reflective coating on either side, while a transparent sapphire case back showcases the watch's movement. This timepiece boasts a water resistance of up to 10 ATM.

The mother-of-pearl dial displays the well-known 3-6-9 chronograph counters in vibrant colors. Hour markers crafted from gold with a faceted design are treated with Super-LumiNova C1, complementing the gold-plated hands which also feature a beige luminescent coating. A date function is conveniently placed at 4:30. The heart of this watch is the El Primero 3600, an automatic chronograph that beats at 36,000 vibrations per hour and offers around 60 hours of power reserve. It consists of 311 finely crafted components and 35 jewels, indicating the central hours and minutes, with a small seconds display at 9 o'clock, and chronograph functions including a 60-second scale at 3 o'clock and a 60-minute totalizer at 6 o'clock. The central chronograph hand makes a complete rotation in 10 seconds, and the movement features a stop-seconds function and a star-shaped oscillating weight with satin finishes. Completing the look, this watch comes with a two-tone bracelet made from stainless steel and rose gold, fastened with a folding clasp, and also includes an additional black rubber strap for versatile styling.
