The Audemars Piguet Royal Oak Perpetual Calendar 26674ST.OO.1320ST.01 represents a pinnacle of haute horlogerie. This 41mm stainless steel reference enters AP's permanent collection in pristine, unworn condition, complete with its original box, papers, and certificate. The case measures 41mm across and just 9.5mm thick, combining brushed and polished surfaces with water resistance to 50 metres. The signature octagonal bezel features white gold screws, exemplifying AP's meticulous finishing standards. The dial presents a deep bleu "Grande Tapisserie" pattern with tone-on-tone subdials, set off by applied 18ct white gold hour markers and Royal Oak hands with Super-LumiNova. Driving the watch is AP's ultra-thin Calibre 7138, standing just 4.1mm thick with 422 components and 41 jewels. The movement offers approximately 55 hours of power reserve and features user-friendly, tool-free calendar adjustment via the crown. The integrated stainless steel bracelet mirrors the case's fine finishing and closes with an AP folding clasp, delivering genuine on-wrist elegance.
