On the occasion of the 2025 LVMH Watch Week, Zenith unveiled a rainbow version of its Chronomaster Sport that is more luxurious than ever as well as a skeletonised version of the Defy Skyline Chronograph, with its edgy openwork design that highlights every technical detail of its El Primero movement
Chronomaster Sport Rainbow
Crafted from 18k white gold, this luxurious and colourful take on the Chronomaster Sport features a perfectly balanced 41mm case crowned by a bezel set in ‘Rainbow’ style with 50 baguette-cut gemstones. A bright and colourful palette of 40 sapphires (~3.9cts) is punctuated with 10 baguette-cut diamonds (~1ct) indicating the 10 seconds. Underneath the sapphire crystal, the lacquered dial features the 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 Chronomaster Sport line is powered by an exceptional version of the legendary El Primero movement, the El Primero 3600. Operating at high frequency (5 Hz or 36,000 vph), it has the ability to display 1/10th of a 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. Visible through the sapphire display case back is the blue column wheel and an open rotor with the five-pointed star Zenith. The timepiece comes on an integrated brushed and polished 3-link white gold bracelet and is secured by a safety double folding clasp.
Defy Skyline Chronograph
The dial of the newest version of the Defy Skyline Chronograph is hollowed out with geometric cut outs in a nod to the Zenith “double Z” logo of the 1960s. The three-contrasting grey azuré subdials are openworked. The faceted applied baton hour markers and the hands feature Super-LumiNova for enhanced legibility in all conditions.
Crafted from steel, the 42mm octagonal Defy Skyline case is topped with a 12-facet bezel and flanked by dynamic pushers. The alternating brushed and polished surfaces create a captivating interplay of light and shadows. The display case back secured by four hexagonal screws and the screw-down crown engraved with the Zenith star ensure a 10 ATM water resistance.
The timepiece is powered by an exceptional, skeletonised version of the calibre El Primero 3600. Originally presented in 2019, Calibre 3600 has the unique ability of displaying the 1/10th of a second with unprecedented functionality. To accurately render each of its pulsations visible, its central seconds hand completes a full rotation every 10 seconds instead of the standard 60 seconds. Its steps precisely mark 1/10th of a second against the graduations on the chapter ring. The bi-directional automatic winding mechanism of the El Primero Caliber 3600SK delivers a power reserve of approximately 60 hours.
