The Defy 49.9001.670/78.R781, seen from the bench

The Zenith Defy Classic Ceramic 49.9001.670/78.R781 represents the radical evolution of Le Locle's sports collection. Featuring a 41 mm ceramic case and the in-house caliber Elite 670 SK skeletonized movement with hours, minutes, seconds and date, this model embodies contemporary engineering merged with unconventional aesthetics. The 22 mm lug width is a deliberate design choice reflecting the proportional relationship between case diameter and strap attachment points.
