The perpetual calendarThe perpetual calendar mechanism is a marvel of miniaturisation, a highly sophisticated mechanical reproduction of our calendar. How can a timepiece, merely by the meshing of its toothed wheels, levers and clicks, successfully indicate the day, the date, the month, the moon phases and the leap-year cycle? The heart of the perpetual calendar system lies in the camon which the various lengths of the replica Breitling A253 Men's watch month are defined. The protruding sections around its circumference represent 31-day months, and the notches those of 30 days.

On the same axis, a wheel bearing a cam indicating standard months of February and a leap-year month of February performs one turn every four years and is thus able to keep accurate track of the leap-year cycle.
