Manufacture audemars Piguet presents calibres 

3120 and 3129, two self-winding movements (with 

or without numerical date display) that combine 

functionality and precision timekeeping with the 

highest standard of aesthetics.

TradiTion and innoVaTion

audemars Piguet has always striven to safeguard and 

uphold its independence. this is why the company 

developed its own method of crafting mechanisms, 

particularly with the design of audemars Piguet 

calibres. every aspect bears the unmistakable aP 

signature – bridges arranged harmoniously side by 

side, hand-finished and embellishments components – 

and presents elegant equilibrium, further enhanced 

by the angular balance cock.

The auTomaTic calibre

calibres 3120 and 3129 by audemars Piguet are 

selfwinding movements. the movements of the wrist 

produce the energy required for them to function.

this energy, harnessed by a 22 carat gold oscillating 

weight, is transmitted to the mainspring by a  

gear-train.

as it gradually winds around the barrel-arbor, the 

spring accumulates energy that is then transmitted 

to the watch movement at a steady rate.

the maximum power reserve is reached after a period 

of time varying from several hours to several days, 

depending on the owner and the amount of activity.
