SINN 105 St Sa

The SINN 105 St Sa is an automatic sports watch that combines uncompromising function and high-quality design in a whole new way.

Dressed in a 41mm diameter stainless steel, bead-blasted case, the 105 St Sa timepiece boasts an impressive combination of technical, sporty design and a diverse range of functions. The multifunctional rotating bezel is a versatile special feature of this timepiece.

The advancing minute scale on the bezel 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.

The SINN 105 St Sa watch is waterproof and pressure-resistant to 20 bar.

A matt white dial version (105 St Sa W) is also available.
