This gorgeous model features an 18K pink gold case and beige dial. The contrast with the dreamy moon phase is captivating. Automatic movement (Cal. 7136). 41 jewels. 28,800 vph. Power reserve: approximately 55 hours. 18KPG case (38mm diameter, 9.4mm thick). Water resistant to 5 bar. Limited to 150 pieces worldwide. Price upon request.

The month and leap year are displayed at 3 o'clock, the moon phase at 6 o'clock, the day of the week at 9 o'clock, and the date at 12 o'clock. The subdial has a snailed finish, creating a contrast with the Grand Tapisserie.

 The 38mm diameter case is just 9.4mm thin, even though it is equipped with a perpetual calendar movement. The three-dimensional shape and sharp lines, combining hairline and polished finishes, are a design unique to the Royal Oak. It is also water resistant to 5 bar, making it easy to wear every day.

 The see-through case back allows you to view the newly introduced Cal. 7136. You can enjoy the meticulous craftsmanship of the finish, including the rotor adorned with the brand logo, the Côtes de Genève pattern on the bridges and main plate, the circular graining, and the chamfering. Another key feature of this watch is its high operability, as all operations can be completed with just the crown, thanks to the four-position crown, even though it is equipped with a perpetual calendar mechanism. The case back is engraved with a special logo commemorating the 150th anniversary of the company's founding, and the words "1 of 150 pieces," indicating the limited edition.
