Background
The U1 is Sinn's intermediate submarine steel diver rated to 1,000m. Built from German submarine steel with Tegiment surface hardening, it represents a middle ground between shallow-water sport diving and the extreme depth rating of the U2. Anti-magnetic certification and DNV maritime certification underscore its professional tool-watch intent, making it popular among technical divers and offshore professionals.
