In the 1980s and 1990s Audemars Piguet brought its expertise in complications to the Royal Oak, and reference 25654 became one of the defining perpetual calendar models of that era. This reference is crafted in 18k yellow gold with a matching integrated gold bracelet, pairing the Royal Oak's architectural case with a white dial arranged with sub-dials for the day, date, and month, plus a moon phase display.\u003c\/p\u003e\u003cp\u003eInside is Audemars Piguet's ultra-thin self-winding perpetual calendar movement, built on the manufacture's celebrated calibre 2120 base with an additional calendar module. A perpetual calendar automatically accounts for months of varying length and for leap years, so the date display should not need manual correction until the year 2100 as long as the watch is kept running. It remains one of the most respected expressions of haute horlogerie within a sports watch case.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: Audemars Piguet\u003c\/li\u003e\n\u003cli\u003eCollection: Royal Oak\u003c\/li\u003e\n\u003cli\u003eModel: Royal Oak Perpetual Calendar\u003c\/li\u003e\n\u003cli\u003eReference: 25654BA\u003c\/li\u003e\n\u003cli\u003eCase: 18k yellow gold\u003c\/li\u003e\n\u003cli\u003eDial: White\u003c\/li\u003e\n\u003cli\u003eMovement: Self-winding perpetual calendar, based on calibre 2120\u003c\/li\u003e\n\u003cli\u003eStrap\/Bracelet: Integrated 18k yellow gold bracelet\u003c\/li\u003e\n\u003cli\u003eFunctions: Hours, minutes, perpetual calendar with day, date, month, and leap year indication, moon phase\u003c\/li\u003e\n\u003cli\u003eSpecial Features: Octagonal bezel with eight hexagonal screws, ultra-thin self-winding movement\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Investment Watches Inc","offers":[{"title":"Default Title","offer_id":57457239523654,"sku":"A2433","price":115450.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/5559\/3658\/files\/IMG_1229.png?v=1790791007","url":"https:\/\/www.investmentwatches.com\/products\/audemars-piguet-royal-oak-perpetual-calendar-white-25654ba-1990s","provider":"Investment Watches Inc","version":"1.0","type":"link"}
