657

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.
