About this reference
The Patek Philippe Reference 1527 was produced between 1940 and 1944, with only two known examples featuring the perpetual calendar chronograph complication. This specific 18k yellow gold reference is a precursor to the 2499, utilizing a 37.6mm case that was considered oversized for the era. It houses the Valjoux-based caliber 13''' movement and features a dial with a tachymeter scale, moon phase aperture, and date sub-dial. Collectors value this reference for its historical role as a unique prototype that defined the aesthetic of Patek Philippe’s mid-century complicated watches. Due to its extreme rarity, the watch does not have a standard secondary market bracket, though it commands high-seven-figure prices at auction. In 2010, this specific yellow gold perpetual calendar chronograph sold at Christie’s for approximately $5.7 million, establishing it as one of the most expensive vintage wristwatches ever sold.
