About this watch
The Zenith Defy Skyline Tourbillon 18.9301.3630/67.I001 debuted in 2025 as a 41 mm rose-gold tourbillon model housing the El Primero 3630 calibre. The case has a diameter of 41 mm, a thickness of 11.60 mm, and a lug-to-lug distance of 46.30 mm, with a water-resistance rating of 10 ATM. The watch is supplied on an integrated rose-gold H-link bracelet with folding clasp and complemented by a brick-red rubber strap with matching clasp. Both are compatible with Zenith’s tool-free strap-change system.
The dial is brick red with a sunray finish and engraved four-pointed stars radiating from the tourbillon aperture at 6 o’clock. Time is displayed by central hours and minutes. The tourbillon features a carriage shaped as the Zenith double-Z star, completing one rotation every 60 seconds. The hands and hour markers are faceted and treated with Super-LumiNova SLN C1.
Inside, the El Primero 3630 beats at 36,000 vph (5 Hz) with a 50-hour power reserve. The movement is fitted with a rose-gold star-shaped openworked rotor featuring satin-brushed surfaces and a 3D laser-engraved pattern radiating from the tourbillon.
