The new Audemars Piguet 50th Anniversary Edition 15510 series is the highest version available on the market, featuring interchangeable components compatible with the original. The dial measures 41mm and comes in four colors: green, blue, black, and white. The dial is adorned with a large grid pattern complemented by three-dimensional luminous hour markers and updated Royal Oak hands. The bracelet has been redesigned, with the first four links changing from parallelogram to trapezoidal shapes, gradually decreasing in width and featuring slimmer links for a lighter feel on the wrist!.The movement is equipped with the original integrated movement CALIBRE4302, a true no-balance integrated movement. The direction of the movement's oscillating weight indicates whether it matches the original, as many market claims about movements are often just added faux plates-those in the know understand that you get what you pay for! .The connecting links between the bracelet and the case are designed with the same movable link as the original. The quality of the clasp and the engraving processes match the original, with no color discrepancies in the dial's craftsmanship. The case back is made of brushed stainless steel, and the sapphire crystal is clear and transparent, allowing a full view of the beautiful movement through the glass back! The oscillating weight showcases the 50th-anniversary logo and the Audemars Piguet logo through intricate hollowing techniques, and both the case and movement undergo a mix of satin finishing and polished surfaces.Additionally, the watch has further integrated the case back into the case itself for a more comfortable fit, conforming better to the wrist's curvature. The case and bracelet are crafted from original imported stainless steel, with a hard, wear-resistant surface and a delicate brushed finish that perfectly replicates the original details meticulously!
