Sinn Watch 103 Ti UTC IFR. 103.0794 Silicon. Sinn Watches have created an unmissable timepiece that not only looks smarts but meets the uncompromisingly high standards met by aircraft and helicopter equipment. This Sinn 103 UTC Ti IFR watch is one of the first timepieces certified in accordance with DIN 8330 meaning you get a high functioning and reliable piece of aircraft equipment to be worn on the wrist. The bead blasted titanium case hides the Valjoux 7750 GMT self winding movement with 200 metre water resistance and Ar-Dehumidifying technology. The striking unidirectional pilot’s bezel with minute ratcheting also allows the wearer to measure and check set time intervals. Housed beneath the scratch resistant sapphire crystal glass with antireflective treatment is a matte black dial which features, like most Sinn watches, numerals, indices and hands coated in luminescence and a date aperture at 3 o clock. The Sinn 103 Ti UTC IFR watch is completed by a black silicon strap and folding buckle for effortless wear and comfort.
