Zenith Defy Revival A3643 Watch
The original Zenith Defy A3643 was released in 1969. It's making a comeback in 2026 with the Defy Revival A3643. For added authenticity, Zenith used a high-precision scan of a vintage example to retro-engineer the dial, which features a silver-sunray finish, with two-tier allied hour markers that have a satin-brushed central plane elevated above glossy black-lacquered recesses. The dial also sports lume-filled blocks and faceted hands, a date window at 4:30, and a bold orange rectangle on the seconds hand. Its octagonal stainless steel case measures 37mm and is topped by a 14-sided bezel; the watch is powered by an Elite 670 automatic movement visible through the sapphire exhibition caseback and sits on a stainless steel ladder bracelet.
