Sinn - 105 St Sa

The 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.
