DEFY Skyline in a 41mm black ceramic octagonal case with a faceted bezel, featuring a black sunburst-patterned dial revisiting the emblematic ZENITH four-pointed star. Powered by the El Primero 3620 high-frequency automatic manufacture movement with the very first 1/10th of a second indicator. Interchangeable ceramic bracelet, with a black patterned rubber strap. A second strap is offered to fully experience the interchangeability of the watch. EL PRIMERO 3620 MOVEMENT The DEFY Skyline’s automatic manufacture movement beats at a high frequency of 5Hz (36’000 VpH) and is endowed with a highly efficient bi-directional automatic winding mechanism that delivers a power reserve of 60 hours. BOLDER IN BLACK Clad entirely in black ceramic, this dark execution of the DEFY Skyline takes on a distinct aura of its own, at once brilliant, bold and sleek. As visually outstanding as it is resilient, the black ceramic used in the DEFY Skyline's octagonal case and bracelet is much harder than traditional metals and alloys, making it highly resistant to scratches and visible signs of wear. Powered by the latest generation of the El Primero high-frequency automatic manufacture movement, featuring the world's first 1/10th of a second indicator. The quick strap-change mechanism allows for easy switching between the ceramic bracelet and provided rubber strap.
