857
Ref.: 857.012
A tool watch with zero tolerance for nonsense. The Sinn 857 is a rock-solid 43mm pilot’s watch built from bead-blasted stainless steel and hardened with TEGIMENT tech to keep scratches at bay. The ratcheting bezel locks in precision timing, while Ar-Dehumidifying tech prevents fogging. Toss in magnetic field protection and 200m water resistance, and you’ve got a timepiece that laughs in the face of tough conditions, whether you’re in the cockpit or the great outdoors.
