Audemars Piguet's Royal Oak Selfwinding 41mm 15500ST heralds a significant update from the previous 15400 model. Replacing the 15400, this watch introduces a new movement, the calibre 4302, ensuring enhanced performance and a 70-hour power reserve. The signature 'Grande Tapisserie' pattern on the dial sees subtle alterations, offering a refined aesthetic. Notably, the date window is now positioned at the periphery, better proportioned to the case size. While maintaining the iconic Royal Oak design, this model features broader hands and hour indexes, emphasizing a sportier appeal. The case retains its 41mm diameter but is slightly thicker, showcasing impeccable craftsmanship and a robust, modern movement.
