Oak represented a real novelty in the Audemars universe as it was the brand’s first true sporting pride. It was the first luxury watch in steel with integrated bracelet and since its inception was produced in a variety of materials including full gold, platinum, tantalum, and often embellished with precious stones, the versatility of the Royal Oak helped make it a model adored by the brand’s elite clientele. The present watch is a very rare example of the two-tone reference 5402 in stainless steel and yellow gold. Its remarkable conservation strikes at a first glance with no evident sign on both the bracelet and on the case with the iconic octagonal bezel. The champagne dial with applied baton indexes and hands is untouched and further special quality of this lot since it’s one of the most rare variants to be found. On the case back the serial number 435 and the unusual inscription “OR—ACIER”.
