The special feature of the Yacht-Master 2, its adjustable countdown with mechanical memory and flyback function, provides a very innovative interaction of bezel and movement.

Its ring-command bezel is mechanically linked to the caliber and serves as the trigger for the sophisticated countdown mechanism.
