Audemars Piguet 2120/2800
Perpetual calendar (day, date, month, moon phase, no leap-year display) formed by the 2120 base and the 2800 under-dial module made by Dubois Dépraz; the thinnest automatic perpetual calendar of its time. First used in model 5548 (1978), in the Royal Oak from 1984. An openworked 2120/2800SQ followed in 1982.
