Perpetual Calendar

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.

You'll need an Apple watch with a Mayan calendar app. No mechanical watch will ever be able to do this.
