Sinn 105 St Sa - The sporty watch with multifunctional rotating bezel

Reading Time: 2 minutes

Sinn 105 St Sa combines uncompromising function and high-quality design in a whole new way.

The timepiece boasts an impressive combination of technical, sporty design and a diverse range of functions. It’s not only the reduced, contemporary look which wins over watch experts, but also the multifunctional rotating bezel, which has shown itself to be a versatile special feature. The advancing minute scale on it allows you to measure time.

Or you can use the bidirectional rotating bezel with 12-hour scale to set up a second time zone, with, for example, the hour hand showing the reference time on the dial and the local time on the rotating bezel. 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 black with accents in orange. The day of the week and date display can appear in English or German. And beyond high precision time measurement, you can also observe the refinements of the mechanical movement in great detail through the transparent case back made from sapphire crystal.
