Good morning WatchEx! As I continue to hack away at my collection, I am moving on my fully Tegimented Sinn U1. Absolutely immaculate condition. It’s amazing what the tegimentation process does to harden the steel. No desk rash, no nothing! The “Extras” - Comes with red rubber strap cut to fit wrists that are 7.23” I’m asking $2,200 net to me. I use PayPal, Venmo, and Zelle. I’ll cover CONUS shipping. Specs from Sinn: The case also features TEGIMENT Technology, making it especially scratch-resistant. If you choose a silicone strap, the design of the clasp will also be on a TEGIMENT Technology basis. If you decide to go for a solid bracelet, this also features TEGIMENT Technology. Case and crown made of high-strength, seawater-resistant German Submarine Steel Case and bezel with TEGIMENT Technology and therefore especially scratch-resistant Diameter of case: 44 mm Tested based on European diving equipment standards and certified by DNV Captive diver's bezel with minute ratcheting Crown at 4 o'clock to prevent pressure on the back of the hand Sapphire crystal glass Waterproof and pressure-resistant to 1,000 m diving depth (= 100 bar), certified by DNV Low pressure resistant Let me know what questions you have!
