The DEFY Skyline Chronograph returns in bold black ceramic, following its debut in blue-toned ceramic editions for ZENITH’s 160th anniversary. Lightweight, scratch‑resistant, and coloured throughout, the ceramic enhances the watch’s sharp, architectural lines and modern urban character. A gradient dial, engraved with the DEFY four‑pointed star motif, features three chronograph counters with concentric detailing, while luminescent hands and markers ensure clear legibility.
Powering the watch is the El Primero 3600 calibre, displaying 1/10th‑of‑a‑second precision with a chronograph hand that completes one rotation every 10 seconds. Beating at 5 Hz with a 60‑hour power reserve, the movement is visible through a sapphire case back, showcasing a blued column wheel and star‑shaped rotor.
An integrated quick strap‑change system allows seamless switching between the ceramic bracelet and the included black rubber strap.
