The mechanism of a perpetual calendar is designed such that it must only be advanced by one day on March 1st of the secular year 2100. All displays of the LANGE 1 TOURBILLON PERPETUAL CALENDAR – the outsize date, the retrograde day, the month ring, the aperture leap year, and the moon-phase indication – switch instantaneously and thus always deliver unambiguous readings.
