While the modern ZENITH DEFY collection is the platform for the Manufacture’s numerous innovations, the historical ZENITH DEFY watches of the 20th century stood for robustness, precision and resilience; championing the virtues of traditional Swiss mechanical watchmaking in the face of mass-produced electronic quartz watches. Boldly conceived, the DEFY line paired avant-garde and daring designs with exceptional performance. With the DEFY Revival line, ZENITH is bringing back some of its most emblematic and historically significant DEFY references from the 1960s and 1970s in stunningly accurate detail.
