Audemars Piguet's first 'Royal Oak' watch was introduced by renowned Swiss watchmaker Gérald Genta in 1972 - each of the 500 iterations since has retained the same signature details as the original. Sourced by WINDSOR, this pre-owned stainless steel and 18-karat gold reference features the iconic 'Petite Tapisserie' dial and screw-fastening bezel, inspired by vintage diving helmets.
