Zenith Defy El Primero 21

Ref. 49.9000.9004/78.R582

The 44mm black ceramic case gives this chronograph a purposeful, angular presence on the wrist. Beneath the sapphire crystal, the skeletonised dial opens up to reveal the movement architecture directly, with baton markers around the chapter ring and a power reserve indicator at twelve o'clock. The El Primero 9004 calibre runs two independent escapements: one at 5Hz for standard timekeeping, a second at 50Hz dedicated solely to the chronograph, allowing the central seconds hand to complete a full rotation every second. Power reserve stands at 50 hours. A black rubber strap with alligator leather inlay completes the build, rated to 100 metres.
