Audemars Piguet Royal Oak Day-Date Moonphase ref 25594ST White Dial


You guys know how much we love the 36mm Royal Oaks – mid size but max power!

We have a real beauty to share with you guys that combines the legendary looks of the original Royal Oak with a twist; it’s a complicated watch from one the Grand Maisons d’Horlogerie!

The 25594ST sports a day and date display in the large sub-registers at the three and nine o’clock positions and a moonphase indicator at six o’clock.

It also has one very cool feature: the sub dials and moon phase aperture look like a smiling face and it sure does make us smile when looking at it!
The white dial sports the Royal-Oak’s well-known ‘petite tapisserie’ pattern and tritium lume. The steel case and integrated bracelet are thick and sharp, with crisp edges and beautiful matte brushed and polished finish in great condition that will fit a wrist size up to 19 cm. The movement has been fully serviced by our watchmaker.

What more could you want? A super cool complicated watch that leaves you smiling!

Our Service

Each vintage timepiece is individually selected and carefully inspected by our team of experts. After we buy a watch it is mechanically inspected and fully checked by our watchmaker. If necessary, the movement will be fully serviced and tested to ensure it is running to our exacting standards.

We will always describe the watch as fully as we can in our sales texts. Our zoomable images are of the highest possible quality and form an important part of each watch’s description. We will never hide or cover up any element of any watch we sell.

Key to our unparalleled service is Fedex Priority shipping, fully insured. Once you have received your watch, we encourage you to inspect it thoroughly. If you are not 100% satisfied, please let us know. We offer a 14 days return policy. Simply return the watch to get a full refund of the original purchase price.

Our Warranty

We offer a one-year warranty on the mechanical function of the watch, starting from the day of purchase. We do not guarantee the waterproof nature of any (vintage) watch, unless expressly made in writing. Therefore, our warranty will not cover any damage done to the case and/or movement by water or moisture entering the watch. Our warranty does not apply to accidental damage or mishandling of your watch and does not extend to the bracelet, case parts (including pushers, winding stem, crown and bezel), watch glass, dial and hands.
