SINN Ref. 105 St Sa UTC W - SW 330-2 Self-Winding Caliber 41mm 20ATM

A technical, sporty look complemented by a diverse range of functions: with this watch, we've managed to combine uncompromising function and high-quality design in a whole new way. It's not only the reduced, contemporary form that wins over watch experts, but also the fact that the timepiece can be used as a versatile instrument.

Using the bidirectional rotating bezel with 24-hour ratcheting, you can set up a second time zone. As a result, adjusting the local time only takes a few seconds, without you having to adjust the orange UTC hand using the crown. Of course, you can also set the UTC hand in the conventional way using the crown and leave the rotating bezel in its initial position. The arrow-shaped UTC hand can also be used to roughly determine cardinal points, when the current position of the sun is visible. If you're located in the northern hemisphere, position the dial horizontally and turn the watch so that the 12-hour hand (ignoring daylight savings time) points to the sun. The 24-hour hand then points to the north.

The rotating bezel itself has a captive connection to the bead-blasted case. Its Black Hard Coating on a TEGIMENT Technology basis lends the watch a professional overall look.

The dial comes in matt white with accents in orange. And take the time to have a closer look at all the details of the mechanical movement through the anti-reflective transparent case back made from sapphire crystal.
