The Defy Skyline is Zenith's declaration that high-frequency watchmaking does not have to live behind a traditional dial. A peripheral ring shows tenths of a second in real time, which turns the open dial from a design choice into a functional statement. If you want to actually see El Primero running, this is the watch that shows you.
Zenith launched the Defy Skyline in 2022 as a sport-oriented successor to the Defy 21, built around the newly developed El Primero 3620. The 3620 runs at 36,000 vph and adds a dedicated 1/10-second display on the outer ring, a trick the movement achieves without a separate high-frequency train. The Skyline is a deliberate departure from the Chronomaster line: no chronograph pushers, no retro-revival packaging, just a contemporary integrated-bracelet sport watch aimed at a younger buyer.
Zenith has historically struggled with brand recognition outside collector circles, and the Skyline is a clear attempt to build a catalog entry that reads modern without abandoning the El Primero identity the brand is built on.
The open dial is striking in photos and polarizing in person; the peripheral ring and cutouts create visual busyness that some buyers do not expect after seeing renders. The integrated bracelet is comfortable but links the watch permanently to a specific proportion, so buyers who prefer leather or aftermarket straps will find this a less flexible daily wearer. Quality control on early examples drew scattered complaints about finishing inconsistencies on the case edges, so inspect any pre-owned piece closely before buying.
The 41mm diameter with integrated lugs wears larger than the number suggests; try it on the wrist before committing. Resale on the Skyline is softer than the Chronomaster line because the heritage connection that drives Zenith premiums in the secondary market does not apply here.
