This “Yves Klein'' Perpetual Calendar Royal Oak 25820ST features a striking combination of the iconic Royal Oak case, an unusual vibrant blue dial and a perpetual calendar movement central to the manufacturer’s history. Housed in stainless steel, it embodies much of the spirit and innovation which carried Audemars Piguet forward in the second half of the 20th century. It’s been almost 50 years since the creation of the original Audemars Piguet Royal Oak and this now classic piece is more popular than ever. First unveiled by Audemars Piguet in 1972 and designed by Gerald Genta, who incidentally designed the Patek Philippe Nautilus amongst others, the Royal Oak has become a cultural icon due to its distinctive features and its role as a pioneer for high-end luxury sports watches. Since its introduction, Audemars Piguet has used the Royal Oak Perpetual Calendar as a canvas to experiment with different metal combinations and dial designs. From the tantalum two-tone examples to openwork dials, the collection offers a rich variety of configurations, where the manufacturer has pushed the boundaries of conventional design. This example, with its striking blue dial, speaks to that approach. This seldom-seen, vibrant blue "Yves Klein" is one of the rarest AP Royal Oak Perpetual Calendar Moonphase watches ever released. Extremely Rare and Highly Collectible. “A certain blue enters your soul,” Matisse mused. Indeed, the color blue was a common theme in the avant-garde art of the likes of Henri Matisse and Yves Klein. Fascinated by the sky from a young age, the French painter Yves Klein spent much time developing the perfect shade of vibrant ultramarine blue because he believed it encapsulated the quality of space. The layout of the dial includes all the traditional indications of a perpetual calendar: day, date, astronomical moon (with graduation for moon age) and month. It features original stick hands, a feature rarely found in Royal Oak watches. The sub-dials are slightly recessed, giving the dial greater depth and texture. It features the "Audemars Piguet" signature in the more modern lettering, adopted by the brand towards the end of the millennium. It retains the more understated “Petite Tapisserie” pattern, forming the square and lozenge motif, as seen in earlier executions of the Royal Oak. Newer versions of the Royal Oak have since adopted AP’s bolder “Tapisserie Evolutive” dial pattern, less faithful to the original design. The electric blue “Yves Klein” color is complemented by crisp white indications used throughout the dial. The stainless case and bracelet are excellently finished, with angular, beveled and polished edges - striking the perfect balance between utilitarian function and elegant design. The polished screws, bezel and case edges fantastically contrast with the brushed surface of the case and bracelet. At 39mm in diameter, and only 9.3mm thick, this Royal Oak Quantième Perpétuel case sits comfortably on the wrist. This Royal Oak Quantième Perpétuel is powered by the AP caliber 2120/2802, derived from Jaeger-LeCoultre’s legendary ultra-thin JLC 920 calibre movement. The caliber 2120 was an initial project of Jaeger LeCoultre in 1967, funded and contributed by Audemars Piguet, and famous for its adoption by Audemars Piguet, Patek Philippe and Vacheron Constantin. This Audemars Piguet Royal Oak Perpetual Calendar 25820ST has a mechanical automatic self-winding Audemars Piguet caliber 2120/2802 movement that's rhodium-plated. It's constructed with 38 jewels, 343 components, 12½ lignes, and a shock absorber mechanism. The balance has variable inertia blocks, a mobile stud balance spring holder, and a 21K gold oscillating weight segment. It has bidirectional winding and a self-compensating flat balance spring. There is a suspended barrel, and the shake of the oscillating weight is precise with an annular ring that runs on four jewels. The bridges are hand polished, with polished bevels, satin-brushed edges, and perlage on the recesses. There is a straight-line lever escapement, and a Gyromax balance that's adjusted to heat, cold, isochronism and 5 positions. It includes a hand-engraved skeletonized rotor with a 21K gold segment. The Moon phase is constructed with physical vapor deposited with metal onto sapphire. The mechanism oscillates at a frequency of 19,800 vph (2.5Hz). This Audemars Piguet Royal Oak Perpetual Calendar will self-adjust until the year 2100. · PLEASE
