Defy Skyline Chronograph Skeleton 42mm | Blue Openworked | Ref. 03.9500.3600

The Story

The Zenith Defy Skyline Chronograph Skeleton is a visceral expression of high-frequency watchmaking. This 2025 reference (03.9500.3600) represents the absolute cutting edge of the Defy lineage, stripping away the traditional dial to reveal the architectural soul of the El Primero movement. The blue openworked dial offers a mesmerizing sense of depth, with skeletonized bridges that create a futuristic, 3D landscape on the wrist. It is a timepiece designed for those who demand both avant-garde aesthetics and world-class horological pedigree.

The Craft

At its core beats the legendary El Primero 3600 movement, operating at a high frequency of 36,000 VpH (5 Hz). This allows for a true 1/10th of a second chronograph function, where the central hand completes a full revolution every 10 seconds: a signature Zenith feat. The 42mm faceted steel case, inspired by the original Defy models of the 1960s, features a highly practical quick-change system, allowing you to swap between the integrated steel bracelet and the textured blue rubber strap in seconds without any tools.

Condition & Set

This 2025 example is presented in Unworn condition, with some factory stickers still intact, offering a "fresh from the boutique" experience. It arrives as a Complete Full Set, including the original Zenith presentation box, the 2025 dated warranty card, and both the bracelet and strap options. With its active factory warranty and current MSRP of $16,700, this Defy Skyline Skeleton represents a rare opportunity to secure Zenith’s most exciting modern release in pristine, stickered condition.
