FURTHER READING 

The "SA" on the reference number denotes that this piece is composed of stainless steel and yellow gold, with an 18K yellow gold bezel secured by eight white gold screws. The integral, articulated, two-tone Royal Oak bracelet is completed with stainless steel folding Audemars Piguet clasp. The dial displays three complications; the sub-register at 9 o'clock registers the current day, the one at 3 o'clock shows the date, and the moon phase aperture is at six o'clock. It is easy to see why so many watch enthusiasts consider the Audemars Piguet Royal Oak the holy grail of timepieces as it exemplifies sporty-casual design and Swiss watchmaking of the highest caliber.

This Audemars Piguet Royal Oak ref. 25594 SA has a mechanical automatic Audemars Piguet caliber 2124 movement rhodium-plated, with fausses cotes embellishment. The rotor is mounted on a ball bearing with a peripheral mass in 22K gold. It has a round shape, 26mm diameter, and thickness of 4.55 mm. It is constructed with a smooth balance in Glucydur, 33 rubies (escapement wheel with end stone), a flat balance-spring in Nivarox 1 with an adjustment device with a micrometric screw, Kif anti-shock. The plate is perlage decorated, the bridge and rotor are Vagues de Genève decorated, and Anglage finished, the screw heads are mirror-polished.

This ref. 25594 SA powered by the self-winding caliber 2124/2825 was introduced around 1984. The 2825 moon phase and day date modifiers are put on the base 2124 auto with date window movement, a JLC base caliber fine finished and adjusted at AP.
The screw-down crown controls ALL functions - day, date, moon phase, and of course, the hour and minutes.

Defining the crown positions as follows:

P0 = crown pushed in all the way
P1 = crown out first detente position
P2 = crown out second detente position, or fully out
P0 is a neutral position and allows to wound the automatic movement manually.
P1 = moon phase setting; turning the crown upward (toward 12) advances the moon phase without affecting other settings or functions.
P2 = in this position, the crown directly controls the hour and minute hands. Thus, at 12 am indicated, the date advances, and at 1:30 am, the day of the week advances.
As a result, when you set the time manually, through its 24-hour cycle, the date advances at midnight every day, while the day of the week advances an hour later.
The mechanism oscillates at the frequency of 21,600 vph (3 Hz).
Case, dial, and movement are all signed.
