Description
Distinguished by its “Japan” designation and platinum construction, this 41mm Royal Oak Perpetual Calendar reference 26597PT.OO.1220PT.01 represents Audemars Piguet’s dedication to regional market exclusivity. The grey dial creates a sophisticated contrast against the lustrous platinum case, while the perpetual calendar complication tracks astronomical cycles with mechanical precision through the year 3100. This particular example arrives with complete box and papers documentation, preserving its provenance within the secondary market.
