In the world of watches, time is not only the passage of seconds, but also a quiet dialogue that combines craftsmanship and art. The Swiss luxury watch brand Zenith, with its long history and innovative technology, has always been at the forefront of this dialogue. This year, Zenith once again tells its story with color and precision engineering, launching the Chronomaster Sport Rainbow, a treasure that perfectly combines the spirit of sports and the art of jewelry.
A symphony of colors
The Chronomaster Sport Rainbow is not just a watch, but more like a colorful work of art. The 50 carefully cut rainbow gemstones on the bezel, including 40 sapphires (total weight 3.9 carats) and 10 diamonds (total weight 1 carat), are arranged in the form of a rainbow using extremely sophisticated setting technology. The size, cut and colour of these gemstones are perfectly consistent, making each one a note in the overall harmony.

The dial is designed with black lacquer, which contrasts sharply with the rainbow gemstones. The three classic 3-6-9 tricolor chronograph counters on the dial are Zenith’s iconic design, and the designer pays tribute to the brand’s legendary history. The hour and minute hands inlaid with Super-Luminova luminous coating allow users to read the time clearly even in dim environments, reflecting the fusion of functionality and beauty in design.
The ultimate combination of craftsmanship and precision
The watch is equipped with Zenith's El Primero 3600 movement. This automatic high-frequency chronograph movement is the result of more than half a century of technological advancement of the brand. It runs at a frequency of 36,000 times per hour (5 Hz) and can accurately measure to 1/10 second. The chronograph seconds hand completes one circle in 10 seconds, providing unprecedented time visibility.
Through the transparent sapphire case back, users can appreciate the architectural beauty of the movement. The blue column wheel and the iconic five-pointed star-shaped rotor have been finely polished and decorated, showing the inner workings of the movement to the fullest. In addition, the movement also has a two-way automatic winding mechanism, providing approximately 60 hours of power reserve, which is suitable for daily wear and can meet the challenges of special occasions.
A dialogue between luxury and sport
The Chronomaster Sport Rainbow's 41 mm case is made of 18K white gold and is paired with a brushed and polished three-link white gold strap, which is both durable and elegant. Its waterproof performance reaches 10 ATM, making it suitable for wearing in various daily or sports occasions. At the same time, the clasp adopts a safe double folding design to ensure that the watch is firm and comfortable. For a watch that combines the spirit of sports and the art of jewelry, the Chronomaster Sport Rainbow is undoubtedly a successful attempt. It is not only eye-catching in design, but also a leader in its category with its high-performance movement and excellent watchmaking technology.
As one of the most innovative brands in the history of Swiss watchmaking, Zenith has always been committed to “challenging the impossible” since its establishment in 1865. From Louis Blériot flying across the English Channel to Felix Baumgartner challenging supersonic free fall, Zenith timepieces have always accompanied those brave enough to push the limits. Today, this brand spirit continues on the Chronomaster Sport Rainbow watch, inspiring every wearer to pursue his or her own rainbow dream.
