Zenith Defy Skyline Chrono Rose Gold / Grey

About this watch

The Zenith Defy Skyline Chronograph 18.9500.3600/21.I001 debuted in 2025 as a 42 mm rose-gold chronograph using the El Primero 3600 calibre. The case is 42 mm in diameter, 12.70 mm thick, and 47.40 mm lug-to-lug, with a water-resistance rating of 10 ATM. The watch is delivered on an integrated rose-gold H-link bracelet with folding clasp, together with a black rubber strap with matching clasp. Both can be exchanged through the tool-free strap-change mechanism. The gradient slate-grey dial has a sunray finish and is embossed with Zenith鈥檚 starry-sky motif. Displays include central hours and minutes, a date at 4:30, and chronograph indications with true 1/10th-of-a-second resolution. Hands and indices are faceted and treated with Super-LumiNova SLN C1, with solid-gold hands for the primary time display. The El Primero 3600 operates at 36,000 vph (5 Hz) and features a central chronograph hand performing one full rotation every ten seconds. The power reserve is 60 hours, and the movement uses a silicon escape wheel and lever. A rose-gold rotor with satin finishing is visible through the sapphire case back.
