Sinn 856 S UTC Silicone Watch

Series 856 - Pilot's watch with protection against magnetic fields.

The ultimate in functionality, this watch features an anti-reflective black dial delivering exceptional legibility - optimized contrast with oversized hands, indices, and numerals ensures intuitive, instant readability even in the most extreme conditions.

The Watch
Topped by a double anti-reflective sapphire crystal, the round case is crafted from stainless steel with a black PVD coating. It measures 40 mm in diameter, 11 mm thick, and weighs 70 grams without the strap. The matte black dial features white Arabic numerals, luminescent white hands and indices, and a date window at 4 o'clock. A 4^th hand displays a second time zone in 24h mode. The screw-down case back is nickel-free, and the crown at 3 o'clock is also screw-down.

This watch is fitted with a black silicone strap with a deployment clasp. This model is designed for water resistance of 20 atmospheres, equivalent to approximately 200 meters. It can be used for swimming and scuba diving.

Specific Technical Features
The entire case of the 856 S UTC has undergone TEGIMENT anti-impact treatment. This surface-hardening technology provides highly effective protection for stainless steel against scratches.

This watch also features Sinn's patented Ar dehumidification technology. This technology slows the aging process of the watch's internal components, extending the movement's service life. It also prevents condensation from forming on the crystal during sudden temperature changes.

This watch also offers protection against magnetic fields up to 80,000 A/m.

The Movement
This watch houses a Swiss Sellita SW300-1 automatic self-winding movement. This 25-jewel caliber displays hours, minutes, seconds, and date via an aperture window. It also features a second time zone display in 24h mode. Equipped with a Stop-Second mechanism for precise time-setting to the second. This movement runs at 28,800 A/h with a 42-hour power reserve.
