Patek Philippe reinterprets the perpetual calendar with retrograde date hand in a new white gold version exuding an original, contemporary style, featuring a dial in gray metallized sapphire crystal revealing the watch's mechanical heart.

The retrograde date as well as the aperture frames of the day (at 9 o'clock), leap-year cycle (at 12 o'clock) month (at 3 o'clock) and moon phases (at 6 o'clock) are underlined by a gray electroplated outline.

The bezel and the caseback are enhanced by the famous hobnail pattern, one of the finest emblems of Patek Philippe style.
