Uncommon 1970s Zenith Defy Gauss 38mm Steel Watch

In the early 1970s, Zenith sold the Defy Gauss to compete with the anti-magnetic Rolex Milgauss 1019 and IWC Ingenieur. Only black 550, 600 blue, and 950 silver dial watches were made. The futuristic 38mm stainless steel, tonneau case is in great shape with few wear marks and the crystal is clean. The inner brass shield is missing but the outer case back keeps the movement protected. It use a Zenith caliber 2562pc high frequency 28.8k movement that’s running well. The ‘lobster’ bracelet is in great shape with few wear marks and fits a 7.5” wrist. Watch only. What you see is what you get. Sold as is. No returns.
