Sinn Pilot's Watch 857 S Ref. 857.021

ased on the 856 series, and designed as a functional instrument watch in the tradition of Sinns' cockpit navigation clocks, this pilot watch also features a pilot's bezel which permits its wearer to measure or check set time intervals. The stainless steel pilot's bezel with minute ratcheting can be rotated on both sides and features a special mechanical system developed by SINN to protect against loss. Like the case material, the base of the bezel is tempered with TEGIMENT Technology. The labelling is silver on an inset, black anodised aluminium ring to ensure optimal scale readability. A luminous triangle serves as the 0 / 60 minute mark. The pilot’s bezel can be turned in both directions and clicks firmly and audibly into place at minute intervals.
