The perpetual calendar functions are shown by hands. The days are positioned at 6 o'clock, the months and leap years at 9 o'clock and the date at 12 o'clock. The moon cycle is reproduced on a round window, 8.50 mm in diameter, positioned at 3 o'clock so that two moons appear to alternate beneath the sapphire, part of which is in fumé glass. On the mechanical chronograph, the seconds hand is in the centre, the hour counter is at 6 o'clock
and the 30-minute counter is at 9 o'clock.
