Explore Sinn

Sinn’s watches tend to look as though someone settled every design question by asking what would help on the job. That approach traces back to 1961, when pilot and flight instructor Helmut Sinn founded the company in Frankfurt, Germany, making cockpit clocks and pilot’s chronographs. Clear scales, strong contrast, and cases built for use still define much of the range.

The 103 carries that aviation background most directly: a rotating bezel, prominent pushers, and a dial that gives the chronograph proper room. The smaller 356 offers a gentler silhouette without losing the instrument-like clarity. Then there’s the 556, whose restrained dial and compact proportions make a convincing argument for keeping things simple.

Underwater, Sinn adopts a different visual language. The U1 pairs German submarine steel with blunt, block-shaped hands and red accents; its hardened bezel addresses the knocks a working dive watch can take. Elsewhere in the collection, Ar-Dehumidifying Technology uses a drying capsule to manage moisture inside the case—engineering you can actually see.
