rafted from 18k white gold, this luxurious and colourful take on the Chronomaster Sport follows the version in rose gold set with baguette-cut diamonds, spinels and sapphires that was presented last year. It further asserts Zenith’s mastery in combining innovative watchmaking and gem-setting.

With it, the perfectly balanced 41mm Chronomaster Sport case is crowned by a bezel set in ’Rainbow’ style with 50 baguette-cut gemstones. To enhance its style while preserving its functionality, a bright and colourful palette of 40 sapphires ( 3.9cts) is punctuated with 10 baguette-cut diamonds ( 1ct) indicating the 10 seconds. The chromatic harmony results from a unique alliance of gem-setting expertise and style. Sourcing gemstones of this caliber, in perfectly uniform size, cut and colours are an extremely challenging endeavor.

Underneath the sapphire crystal, the lacquered dial features signature 3-6-9 tricolour overlapping counters. The rainbow bezel is echoed with sapphire markers. These are set on a deep black surface creating a perfect backdrop for them to shine. To enhance legibility in the dark, the faceted hour and minute hands are fitted with Super Luminova.

The result of 55 years of perfecting the El Primero, the world’s first automatic high-frequency chronograph calibre, the Chronomaster Sport line is powered by an exceptional version of this legendary movement, the El Primero 3600. Operating at high frequency (5 Hz or 36,000 vph), it has the ability to display 1/10th of second with unprecedented readability as the chronograph second hands makes a complete dial rotation in just 10 seconds.

Featuring bi-directional winding, its automatic mechanism delivers a power reserve of 60 hours. Its superb architecture is visible through the sapphire display case back, revealing a blue column wheel and an open rotor with the five-pointed star Zenith.

Exuding dazzling presence on the wrist, the Zenith Chronomaster Sport Rainbow comes on an integrated brushed and polished 3-link white gold bracelet. It is secured by a safety double folding clasp.

The Chronomaster Sport Rainbow is available exclusively from Zenith’s physical and online boutiques worldwide.
