U1 SDR
Ref.: 1010.04
Serious dive watch cred with a stealthy twist. The Sinn U1 SDR keeps the brand’s signature German submarine steel toughness but adds a black bezel for extra attitude. At 44mm, it’s built like a tank, with 1,000m water resistance and TEGIMENT coating to keep scratches at bay. The matte black dial keeps things ultra-legible, making this the kind of watch that works just as well under the waves as it does on dry land.
