The Defy 32.9001.670/78.R590, seen from the bench

The Zenith Defy 32.9001.670/78.R590 represents the radical evolution of the Defy collection. The 41mm titanium case, set with diamonds, pairs with the Zenith caliber Elite 670 SK automatic movement visible through the skeleton caseback. This movement delivers ±3 seconds per day accuracy and 50 hours power reserve, with 4 Hz balance oscillation. The 20mm lug width reflects Zenith's ergonomic proportions for this model, balancing the geometric casing geometry with wrist elegance.
