Series 856 - Pilot's watch with protection against magnetic fields.
A must for functionality, this watch features an anti-reflective black dial for perfect legibility - optimal contrast with oversized hands, indices, and numerals ensures intuitive reading even in extreme conditions.
The Watch
Topped by a double anti-reflective sapphire crystal, the round stainless steel case features a satin finish. It measures 40 mm in diameter, 11 mm thick, and weighs 70 grams without the strap. The matte black dial displays white Arabic numerals, 3 white luminescent hands and indices, and a date window at 4 o'clock. The caseback is screwed down and nickel-free. The crown at 3 o'clock is also screwed down.
This watch comes fitted with a black silicone strap with a folding clasp. Water-resistant to 20 ATM (200 meters), it is suitable for swimming and scuba diving.
Specific Technical Features
The entire case of the 856 has undergone a TEGIMENT anti-impact treatment. This surface-hardening technology provides highly effective protection against scratches on the stainless steel.
This watch also features Ar dehumidification technology, patented by Sinn. This technology slows down the aging 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 movement. This 25-jewel caliber displays hours, minutes, seconds, and the date in a window. It features a Stop-Seconds device for precise time-setting to the second. The movement runs at 28,800 A/h with a 42-hour power reserve.
