About this watch

The Audemars Piguet Royal Oak Extra-Thin Platinum 15206PT.OO.1240PT.01 is a masterpiece of luxury watchmaking. This limited edition, with only 70 units produced, showcases the brand's commitment to excellence and innovation. The platinum casing and ultra-thin profile make it a head-turner, while the black onyx dial creates a striking contrast against the metal case. The gem-set indexes add a touch of sparkle, elevating the overall look. This watch is not just a timepiece; it's a statement of luxury and exclusivity. With its 39mm diameter and 9.80mm height, it sits snugly on the wrist without feeling bulky. The water resistance of up to 50 meters makes it suitable for everyday wear, from beach to meeting. This watch is an investment in both style and heritage, perfect for collectors and watch enthusiasts alike. Its remarkable movement, the Audemars Piguet caliber AP 2121, is a marvel in itself, originally designed by Jaeger-LeCoultre. The slim profile of just 3.05mm makes it one of the thinnest automatic movements on the market. This watch is a true reflection of the brand's philosophy: to create watches that are both technically advanced and aesthetically pleasing.
