Current 41mm Royal Oak black dial.

With a few subtle, but important changes by Audemars Piguet (wider baton hour markers, re-positioned date window, and the addition of a discreet minute track) this 41mm ref 15500ST with the sought-after black Grande Tapisserie dial, offers a more balanced aesthetic over its 15400ST predecessor. Self-winding calibre 4302 movement, with 70hr power-reserve, waterproof to 50m. 

Accompanied with its Audemars Piguet box, instruction booklets and AP international warranty card (with the option to extend to 2025).
