308 Hunter

New 2026 Release | Moonlight indicator and centrally mounted date hand

Building on the success of the Sinn 3006 Hunter Chronograph, the new Sinn 308 Hunter was designed to offer a scaled back variation of the same design in a brand new midsize 40 mm case with a 56 hour power reserve. Sinn engineered a luminous ceramic material that incorporates SuperLuminova (glows green) into the actual casting process rather than simply painting the markers after they are produced. These applied hour markers are applied to the dial by hand.

544

New 2026 Release | Automatic winding mechanical watch with 60+ hour power reserve

The Sinn 544 may be a brand new addition to Sinn's collection of tool watches, but the design language is actually inspired by models like the Sinn 244 and the Sinn 444 from the early 2000s. At 38.5 mm, the midsize case of the new Sinn 544 hits the sweet spot for most wearers today. The hours are labeled around the dial on a fixed interior bezel, and the white seconds hand contrasts starkly against the matte black dial for excellent legibility.

HANHART

Preventor HD12 Collection


The process of creating HD12 steel begins with the diffusion of carbon into the stainless steel, creating a gradual transition from a hard surface to a softer core which helps prevent brittleness.

Next, a transparent finish is then applied via a physical vapor deposition process for additional protection, bringing the total surface hardness to 1,200 HV. At only 200 - 300 HV, conventional 316L stainless steel watch cases are no match for HD12 steel.
