Sinn Instrument 657 S D SN-046

This pilot’s timepiece is a relatively new addition to the Sinn instrumental watches collection. It comes with ETA 2824-2 automatic movement that performs 28 800 vibrations per hour and has 25 bearing jewels. The extreme protection from magnetic influences makes this watch extra special. A number of features have been added for the convenience of the wearer – captive pilot’s bezel with minute ratcheting, a date window located between the 4 and 5 o’clock marks, luminous hands and markers, pressure resistance and scratch-resistant sapphire crystal glass with anti-reflective coating.
