The Chronomaster Sport Rainbow, a contemporary example of Zenith's approach to luxury watchmaking, is made to function as much as it is to draw attention.
The Zenith Chronomaster Sport Rainbow is a watch that is notable for both its functionality and appearance, thanks to its bold design and technical precision. It was unveiled during LVMH Watch Week 2025 and embraces contemporary colour and gem-setting trends while continuing Zenith's long history of chronographs. The watch's high-frequency El Primero movement, upscale materials, and rainbow bezel demonstrate how innovation and craftsmanship can coexist in harmony.
Combining exceptional watchmaking accuracy with striking luxury, the Zenith Chronomaster Sport Rainbow is a striking and colorful statement piece. It provides 1/10th of a second timekeeping and is powered by the El Primero 3600, an in-house high-frequency chronograph movement that was introduced in 2019. For easy, dynamic readability, the chronograph hand completes a full sweep every 10 seconds. Through the sapphire caseback, the movement, which features Zenith's recognizable star-shaped rotor and a blued column wheel, is visible, beating at 5 Hz with a 60-hour power reserve.
Super-LumiNova is applied to the Chronomaster Sport Rainbow's hands and indices to improve visibility in low-light conditions and throughout the day. The El Primero 3600's renowned 1/10th of a second precision is elegantly displayed by the rhodium-plated central chronograph hand, which sweeps the dial every 10 seconds and is distinguished by its star-shaped counterweight.
Water-resistant up to 100 meters, it is more than just a showpiece; it's a high-performing device encased in a range of luxury.
Initial reactions to Zenith's Chronomaster Sport were mixed, with many people pointing out that it looked a lot like a famous chronograph from another well-known Swiss company. Critics made snap comparisons, ignoring the subtleties of Zenith's own chronograph heritage and the unique characteristics that made the El Primero unique. These comparisons are now being brought back to life with the Chronomaster Sport Rainbow's debut during LVMH Watch Week 2025, as the piece capitalizes on the vibrant gem-set trend frequently connected to that same competing brand. However, this new release is anything but derivative when evaluated on its own merits. This dynamic, high-performing chronograph demonstrates Zenith's technical mastery, handcrafted finishing, and readiness to embrace playful luxury without sacrificing its heritage.
In addition to a gem-set bezel set with 5.36 carats of baguette-cut sapphires and diamonds, the watch has a 41mm 18k white gold case with brushed and polished finishes. Its black lacquered dial features rainbow sapphire indices, a date window at 4:30, and Zenith's recognizable tricolour sub-dials, giving it a fun yet sophisticated twist. Super-LumiNova is applied to the rhodium-plated hands and the star-tipped chronograph seconds hand to improve visibility. A matching three-link bracelet made of 18k white gold, which combines elegance and comfort, completes the set. It is secured with a safety folding clasp. This Chronomaster Sport Rainbow, which is water-resistant up to 100 meters, is more than just a showpiece; it's a high-performing device encased in a range of luxury.
