The automatic calibre AP 2326/2847 was developed by Audemars Piguet specifically for this watch. In addition to displaying hours and minutes the movement has a small second at the “3”. The chronograph with its central seconds hand has a 6-hour counter (at the “6”) and a 20-minute counter (at the “9”), which scale is decorated with the Alinghi logo. In addition, the flyback chronograph is equipped with a central 10-minute counter. The display window below the “12” turns red in the last minute before the starting signal for the regatta.
