sinn U2 which parts are tegimented?

[hunz]

is it just the bezel, or also the case, case back and crown?

i understand the buckle is not tegimented unless you upgrade separately

wasn't sure if there was two models. 1. standard - only the bezel, and 2.the watch is fully tegimented.

also, i assume the above parts are submarine steel?

only the bezel. But there are a few pieces of U1 & 2 that are fully tegimented...a special production batch.
