On the dial, hand-engraved on a rose engine in the traditional manner, one can read the different indications pertaining to the time, date, moon phases and power reserve.
The Perpetual Calendar 5327 with a power reserve indicatior is equipped with a revised and improved extra-flat automatic movement, that operates its various functions in perfect symmetry, on a hand-guilloché silvered gold dial: the moon phases at 1:30 face the power reserve at 10:30; the leap year at 8 o’clock respond to the days at 4 o’clock; the date is at 6 o’clock; and the hours, minutes and month are found in the centre. Four correctors complete this exceptional mechanism, whose complexity is revealed through the sapphire crystal caseback.

Power reserve indicator
The power reserve indicator displays the remaining autonomy of the movement before it needs to be wound. It makes it possible to monitor the energy available in the barrel, while adding a direct mechanical reading to the dial.
Moon phase
The moon phase reproduces the progression of the lunar cycle on the dial. A complication that is both astronomical and decorative, it combines the reading of time with a poetic representation of the sky.
Calendar
The calendar displays the date on the dial, generally by aperture, hand or disc. Simple in appearance, this indication requires precise integration both into the movement and into the balance of the dial.
