856 S UTC Leather Watch

Series 856 - Aviator Watch with magnetic field protection.

A benchmark in functionality, this watch features an anti-reflective black dial engineered for perfect legibility - oversized hands, indices, and numerals deliver intuitive, unambiguous readability even in extreme conditions.

The Watch
Topped with a double anti-reflective sapphire crystal, the round case is crafted from stainless steel with a black PVD coating. It measures 40mm in diameter, 11mm 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 24-hour mode. The screw-back case is nickel-free, and the crown at 3 o'clock is also screwed down.

This watch features a black leather strap with a pin buckle. Water-resistant to 20 atmospheres (200m), 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 against scratches on stainless steel.

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 lifespan. 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 is powered by a Swiss Sellita SW330-1 automatic movement. This 25-jewel caliber displays hours, minutes, seconds, and date via a window. It also offers a second time zone in 24-hour mode and is equipped with a hacking seconds device for precise time-setting. The movement runs at 28,800 vph with a 42-hour power reserve.
