Audemars Piguet Royal Oak Selfwinding (Bleu Nuit Nuage 50 / Blue Dial)

The definitive configuration of the legendary haute horlogerie sports watch, featuring a stainless steel case and the signature octagonal bezel with eight visible hexagonal screws. The dial showcases the iconic "Grande Tapisserie" waffle pattern in a deep blue hue—reminiscent of the historic "Bleu Nuit Nuage 50" shade—complemented by white gold applied hour-markers and luminescent hands. A clean, color-matched date display sits precisely at the 3 o'clock position.
