The Audemars Piguet Royal Oak was designed by Gérald Genta and introduced in 1972 as the first luxury sports watch in steel, defined by its octagonal bezel secured with eight hexagonal screws and its fully integrated bracelet. 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.

Inside 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.
