About the PAM00423's Caliber P.3002 Movement:
The P.3002 movement has large bridges, two spring barrels giving a power reserve of three days and a balance wheel 13.2 mm in diameter with variable inertia, enabling the rate of the watch to be adjusted through external screws on the rim. The movement also offers a seconds zero reset device and a mechanism for the rapid adjustment of the hour, enabling the hour hand to jump one hour at a time, without interfering with the movement of the minute hand or the running of the watch.
