Sinn 857 S

Description

Model: 857.021

Based on the 856 series, and designed as a functional instrument watch in the tradition of SINN’s cockpit navigation clocks, this pilot’s watch also features a pilot’s bezel which permits its wearer to measure or check set time intervals. This is a decisive criterion particularly in aviation – reason enough for SINN to give this important function a superior design.

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.
