The Sinn pictured is GRAB and KEEP!!! UTTtrading (Ted) is right. That steel is special. For that watch (and 1 or 2 other models from Sinn....my jurassic memory escapes me now), Sinn uses metallurgy from submarines and its steel virtually scratch-proof. Nice, understated watch.
sadly on U1 the only part of the watch that is of the tegmented (hardened like a submarine hull) steel is the bezel...most of their spendier chrono's are 100% tegmented. supposedly it is like 1500 vickers (hardness scale).
