Notes

The Audemars Piguet Royal Oak Perpetual Calendar Skeleton Ref. 25829OR.OO.0944OR.01 in 18K pink gold stands as a truly remarkable horological masterpiece. As one of only 174 pink gold examples crafted between 1996 and 2013, this timepiece embodies exceptional rarity and represents the pinnacle of artisanal mastery.

Its transparent skeleton design elegantly unveils the perpetual calendar mechanism—a horological marvel that precisely tracks days, dates, months, leap years, and moon phases. Each component displays meticulous handfinishing, from meticulously polished angles to delicate Côtes de Genève s triping.

This particular example recently completed servicing at Audemars Piguet in April 2025. The watch remains in excellent overall condition. Both the hallmarks on the back of the lugs and the numerals engraved on the case back present with outstanding definition and clarity.
