The Master Ultra Thin 1302520 (aka: Q1302520), seen from the bench

The Master Ultra Thin Perpetual Calendar features the Jaeger-LeCoultre caliber 868/1 with perpetual calendar complications, moon phase indication and hour, minute, second functions. The movement manages the indication of date, day, month and year with automatic correction for months of different lengths and leap years. The Q1302520 reference maintains the characteristic slim profile of the Master Ultra Thin collection despite the complexity of the movement.
