This beauty combines the legendary design of the original Royal Oak with classic 36 mm case size—but with a twist: it is also a bona fide complicated watch from one of the great Grandes Maisons of horology , introduced in 1984.

The reference 25594ST features day and date displays in large sub-registers at the 3 and 9 o’clock positions, along with a moonphase indicator at 6 o’clock. And then there’s the charm: the layout of the sub-dials and moonphase creates the impression of a smiling face—it’s nearly impossible not to smile back while looking at it.

The white MK1 dial showcases the Royal Oak’s iconic “petite tapisserie” pattern, complemented by tritium lume and the discreet Audemars Piguet signature. The stainless steel case and integrated bracelet are strong and sharply defined, with crisp edges and a beautiful combination of matte brushing and polished finishes. Preserved in exceptional condition, the bracelet comfortably fits wrists up to 18.5 cm.

This fine Audemars Piguet has been fully serviced by our AP-trained watchmaker and is ready to be enjoyed for many years to come.

A Royal Oak that brings both technical sophistication and quiet joy to the wrist—one glance at that smiling dial, and you may find yourself smiling to the 🌙, get in touch !
