Zenith Defy Skyline Skeleton Steel — Openworked Dial | Ref. 03.9300.3620/79.I001

Architecture revealed: the Defy Skyline Skeleton strips watchmaking to its magnificent bones, presenting the El Primero movement as both engine and artwork within a 41 mm stainless steel case. Zenith's legendary El Primero calibre — the world's first automatic high-frequency chronograph, beating at 36,000 vibrations per hour since 1969 — here takes centre stage through an openworked dial that grants the wearer an unobstructed view of mechanical artistry in perpetual motion. Every bridge, wheel, and escapement becomes part of the visual language.

The stainless steel case, paired with a matching stainless steel bracelet and secure folding buckle, anchors the watch in the Defy lineage: bold, progressive, and built to perform. With approximately 55 hours of power reserve and water resistance rated to 10 ATM, the Skyline Skeleton is engineered for the demands of modern life while never surrendering its identity as a showcase of haute horlogerie. The geometry of the case — angular and assertive — mirrors the complexity it frames.

Wearing the Defy Skyline Skeleton is a declaration of intellectual curiosity. It is a watch for those who appreciate that the finest mechanisms deserve to be seen, not hidden — where transparency is a form of confidence. From Le Locle to the world's most discerning wrists, this is Zenith's open invitation to look closer. Time to reach your star.
