Defy Skyline

This Zenith Defy Skyline Chronograph Skeleton reference 03.9500.3600/79.I001 is a striking certified pre-owned luxury watch, presented in new condition and delivered as a full set with its original box and papers. Blending avant-garde design with Zenith’s legendary high-frequency chronograph expertise, this model is the modern, architectural evolution of the Defy line.

The watch features a 42 mm stainless steel case, offering a strong yet refined wrist presence with sharp, contemporary lines. Its openworked skeleton dial reveals the geometric bridges and chronograph architecture beneath, delivering depth, transparency, and immediate visual impact. Faceted hands and applied markers ensure excellent legibility despite the open design, while the integrated stainless steel bracelet enhances comfort and reinforces the watch’s cohesive, sporty character.

Powering this timepiece is the Zenith El Primero Calibre 3600SK, an in-house automatic skeletonised chronograph movement beating at 36,000 vibrations per hour (5 Hz). This high frequency enables true 1/10th of a second chronograph measurement, with the central chronograph hand completing one full rotation every 10 seconds. The movement offers a power reserve of approximately 60 hours, combining precision, robustness, and modern engineering.

This example is offered in never worn condition, with the case, bracelet, dial, and crystal preserved in pristine state, showing no signs of use.

Delivered with its original Zenith box and original papers, this pre-owned Zenith Defy Skyline Chronograph Skeleton is an exceptional opportunity to acquire a contemporary high-performance chronograph with advanced design and complete documentation.
