Introduction
Launched in 2024 as an extension of the Defy collection, inspired by Zenith’s family of 1969 tough sports watches named after the Defi collection of pocketwatches, the Defy Skyline Skeleton is one of Zenith’s most impressive offerings yet. Boasting a twelve-sided bezel and an angular white ceramic case, the Defy Skyline Skeleton’s sporty aesthetic undersells the amount of artisanal craftsmanship required to create its skeletonized dial and movement. Powered by the automatic El Primero cal. 3630 high-frequency manufacture movement, the Defy Skyline Skeleton is one of Zenith’s finest modern watches. Beating at an impressive 5Hz, the El Primero cal. 3630 boasts an impressive 55-hour power reserve and displays some elaborate finishings throughout. Featuring an openworked star-shaped winding rotor that sits atop brushed blue bridges decorated with Côtes de Genève stripes, he movement echoes the aesthetic achieved by the Defy Skyline’s stunning blue dial, which also features the same blue color thanks to its use of the movement architecture to create its display. An impressive example of Zenith’s abilities as a watchmaker, it is timepieces like the Defy Skyline Skeleton that showcase why the brand has been a supplier of movements to other brands for years.

THE DIAL
Boasting a blue openworked dial made up of the various bridges that make up its automatic movement beneath a star-shaped skeleton that serves as the primary foundation for its indices and subdial, the Defy Skyline Skeleton's display is a lesson in craftsmanship and attention to detail.

THE CONSTRUCTION
Aggressive, angular and sporty, the Defy Skyline Skeleton wears exactly as one would expect an integrated bracelet sports watch to wear, but with the might of its technically impressive white ceramic case and integrated bracelet.

TIMING MACHINE READOUT
This reading was taken (crown down) with a ONEOF Accuracy Boutique Edition timing machine at time of cataloging. It is provided as a courtesy only, and shall not be construed as a warranty or guarantee of any kind. Please refer to our terms and conditions of sale for more information.
Condition
Watch is in overall excellent condition. The white ceramic case shows surface scratches and marks, most noticeably on the bezel and upper right lug, while the display case back retains well-defined engravings around the outer edge. The dial and hands remain like new. It is fitted with a white ceramic bracelet showing light surface marks. The bracelet is fitted with 19 links and fits approximately a 6¾” wrist. The removed additional links are included. Comes complete with box and papers, along with a spare white Zenith rubber strap and steel pin buckle.
Our Perspective
An example of Zenith's impressive capabilities as a watchmaker, the Defy Skyline Skeleton highlights how brands who might be known for something else, chronographs in Zenith's case, are more than capable of excelling in something else.
