Zenith Defy Extreme Carbon — Tinted Sapphire Dial with Copper Counters | Ref. 5/27.I307

Born from the adrenaline-charged world of Extreme E off-road racing, the Defy Extreme E Copper X Prix is Zenith's most visceral expression of motorsport horology. The 45 mm case marries aerospace-grade carbon fibre with a titanium caseback and crown architecture, keeping weight dramatically low while delivering uncompromising structural rigidity. Against the blackened tinted sapphire dial, three copper-coloured counters create a visual narrative of speed — at once functional and boldly aesthetic.

At its heart beats Zenith's storied El Primero movement, upgraded here to achieve the extraordinary precision of 1/100th of a second measurement — a feat previously confined to laboratory timekeeping. Oscillating at 360,000 vibrations per hour, this calibre captures fleeting moments that conventional chronographs simply cannot resolve. Approximately 50 hours of power reserve ensure that endurance matches its sprint-ready credentials. The microblasted titanium triple folding buckle locks the copper Velcro strap — itself fabricated from recycled racing tyres — with unshakeable security.

The Defy Extreme E Copper X Prix is a statement of intent for those who understand that sustainable ambition and mechanical excellence are not contradictions. Water-resistant to 20 ATM, it transitions effortlessly from the starting grid to any aquatic challenge. Zenith's motto — Time to reach your star — resonates nowhere more powerfully than in this collaboration where horology and environmental consciousness converge in a watch priced at $21,680.
