Offered in excellent overall condition, the present timepiece provides the opportunity for collectors to own one of the hottest watches of Audemars Piguet modern production.

In 2018, Audemars Piguet introduced the RD#2 as a prototype, with 'RD' standing for 'Research and Development', reflecting their commitment to pushing the boundaries of watchmaking.

The RD#2's movement, at just 2.89 mm. thick, was even slimmer than the ultra-thin three-hand calibers. Audemars Piguet further slimmed the case to an impressive 6.2 mm., making subtle changes to the signature octagonal Royal Oak design to seamlessly incorporate the perpetual calendar mechanism. The iconic tapisserie dial, was replaced with a modern, matte blue dial. The result is a distinctly contemporary aesthetic that sets the 26586IP reference apart from other Royal Oak perpetual calendars.

At the heart of the RD#2 is the ultra-thin caliber 5133, capable of tracking the date, day, month, leap year, moon phases and day/night. What truly elevates this model is the thoughtful attention to detail and the innovative use of materials - a refined blend of polished platinum and brushed titanium, creating a timepiece that marries elegance with modern design and practicality.
