The Defy Skyline pays tribute to Zenith’s celestial roots through a dial covered in repeating four-pointed stars, arranged like a stylized night sky. The skeletonized El Primero 3620SK takes a similarly unconventional approach by exposing its mechanics instead of concealing them behind traditional architecture, a suitably defiant approach for a collection named Defy.

Its 41mm black ceramic case and bracelet instantly give this model its distinctly stealthy appearance. The openworked rose gold-toned dial introduces a richer, more dimensional look against the black ceramic case. Central hands indicate the hours and minutes, with the display at 6 o’clock measuring tenths of a second. Powering the watch is the high-beat El Primero 3620SK, a 5Hz automatic caliber that stores approximately 55 hours of power reserve.

This is an unworn Zenith Defy Skyline Skeleton Black Ceramic Watch 49.9300.3620/07.I001. It is accompanied by a secondary strap, papers, and the manufacturer’s box.
