Sinn 657 Automatic ETA 2824-2. New Old Stock

New old stock from 2011, never been used Sinn 657 automatic pilot watch with ETA 2824-2 movement. Based on the 656 model range, and designed as a functional instrument watch in the tradition of our 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 us 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. 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.
