Zenith Defy Skyline Tourbillon Skeleton Rose Gold / Blue

About this watch

The Defy Skyline Tourbillon Skeleton extends the Defy Skyline Tourbillon line with a fully skeletonised execution, exposing the architecture of the movement while preserving the collection’s sharply faceted design language. Introduced in 2026, this version is crafted entirely in rose gold and is produced as a limited edition of 50 pieces under reference 18.9300.3630/78.I001. The 41 mm case features the Skyline’s angular construction with a twelve-sided bezel and a screw-down crown, ensuring water resistance to 10 ATM. The openworked blue dial reveals the movement beneath, finished with a combination of blue PVD surfaces and rhodium-plated bevels to enhance contrast and depth. Faceted gold-plated hour markers are applied directly to the skeletonised structure and filled with Super-LumiNova SLN C1, while the solid gold hands are faceted and coated with coloured varnish for legibility against the open background. At 6 o’clock, the one-minute tourbillon serves as the visual and technical focal point. The tourbillon cage consists of 56 components and completes one full rotation every 60 seconds. No date display is present, maintaining an uninterrupted view of the movement architecture. The watch is powered by the automatic El Primero 3630 SK calibre, operating at a high frequency of 36,000 vibrations per hour (5 Hz) and offering a power reserve of approximately 50 hours. The movement features a skeletonised construction and is equipped with a solid gold oscillating weight with satined finishes, visible through the sapphire crystal caseback. The watch is delivered on a solid rose gold bracelet with a matching double folding clasp and includes an interchangeable blue rubber strap fitted with a solid gold folding clasp. A full quick-change strap system allows tool-free interchange between bracelet and strap.
