The Royal Oak Day Date Moon Phase is the ultimate 36mm Royal Oak and a testament to the versatility of Audemars Piguet's products. Although the Royal Oak is usually appreciated with dark dials, particularly blue, the reference 25594SA is the exception that most will agree on, demonstrating that a white dial can be perfectly adapted to a Royal Oak. Contrasting beautifully with the moon phase, the light dial brings freshness and a touch of originality. On top of that, the watch also features two sub-dials that balance the design and add utility to the piece. What makes this watch even more interesting is that the 25594 is the only Royal Oak with a moon phase, apart from the perpetual calendars, which are in a totally different price range.

This spectacular example is fitted with a mk1 dial, characterised by the "small font" (all letters from the "Audemars Piguet" logo on the dial have the same size). The case and bracelet are in excellent condition, still with plenty of material and sharp edges. Although often overlooked, the 36mm cases sit better on most wrists than a Jumbo (39mm) and offer increased comfort due to their lighter weight. The watch is entirely original, apart from the hands and crown, which are service items, as is often the case with these models. It's the perfect starting point for someone looking for a Royal Oak that's out of the ordinary but respects the model's DNA.
