This chronograph with a Tri-Compax counter display measures intervals of time to the second (centre hand), totalling minutes (30-minute counter at 9 o’clock) and hours (12-hour counter at 6 o’clock).

The double aperture, which is approximately twenty percent bigger than a standard aperture, ensures that the date is perfectly readable. It is equipped with the famous rotor protected by Perrelet and its glass covering allows admiring eyes to discover the exquisite workmanship of the movement and the beauty of the ‘tapestry’ decoration.
