Details & Specifications
Description:
The Sinn 757 S is a rugged instrument watch built to honor the tradition of Sinn's navigation cockpit clocks. Part of the Archive 757 series, this blacked-out "S" variant features a Black Hard Coating over Sinn's TEGIMENT Technology case, giving it a durable, scratch-resistant matte black finish.
The stainless steel pilot's bezel features minute ratcheting and can be rotated in both directions, with silver markings on a black anodized aluminum insert and a luminous triangle at the zero position. Beyond its chronograph function, the watch benefits from Sinn's Ar-Dehumidifying Technology to prevent internal fogging, functional temperature resistance from -45°C to +80°C, and magnetic field protection up to 80,000 A/m — making this a true tool watch built for extreme conditions.
