Sinn 105 St Sa UTC Automatic Watch - Black Dial - Solid Bracelet

The Sinn 105 St Sa UTC is a sports watch which won the Red Dot Product Design Award in 2021. Sinn has managed to pack impressive functionality and build quality into a reduced contemporary design.

The 105 benefits from a bidirectional rotating bezel with 24-hour ratcheting, allowing you to set up a secondary time zone with ease. The bezel itself has a captive connection on the bead-blasted 41mm case, created using Black Hard Coating and Tegiment steel hardening technology, making the sports watch impressively durable and scratch resistant.

The dial is incredibly legible thanks to the matte-black design, luminescent indices and hands and anti-reflective sapphire crystal, showing off the Sellita SW330-2 automatic movement under the caseback. Its durable construction makes the 105 low-pressure resistant and waterproof to 200 metres as set out in standard DIN 8310 and antimagnetic as per DIN 8309.

Why This Watch?

• A bidirectional rotating bezel allows for a second time zone to be set up with ease.
• Impressive durability and scratch resistance thanks to Black Hard Coating and Tegiment technology.
• Anti-reflective coating on both sides of the sapphire crystal and luminescent hands and indices makes this watch legible in any light condition.

About Sinn

Sinn Watches was founded in 1961 and has long been a big name in horology. The brand was originally focused on producing navigation clocks for cockpits, and this design is reflected in their collection of pilot watches decades later. Sinn promises uncompromising functionality in their watch collections, even in the most demanding conditions. Thanks to industry leading technologies such as Ar-Dehumidifying and antimagnetic construction, Tegiment steel hardening and temperature stabilized movements. It’s not surprising then, that Sinn is praised for their high-quality movements and materials and loved by collectors for their accuracy in extremely adverse conditions.
