A bold expression of Zenith’s technical innovation in the 1970s, the Defy Gauss 28800 ref. A7688 was purpose-built to withstand magnetic interference (similar to the Rolex Milgauss or IWC Ingenieur), featuring an anti-magnetic movement shield and robust tonneau-shaped case. Its distinctive case design, integrated bracelet, and charming dial accents exemplify the brand’s adventurous design language of the era. Powered by the high-beat Caliber 2562PC ticking at 28,800 vibrations per hour, this reference combines functionality, durability, and unique retro charm.
