Patek Philippe Minute Repeater Perpetual Calendar

About this reference

Patek Philippe produced the Reference 3974 between 1989 and approximately 2000 to commemorate the brand’s 150th anniversary. Collectors prioritize this reference because it was the first automatic minute repeater with a perpetual calendar, powered by the 467-part Caliber R 27 Q. The platinum variant is particularly rare, as the majority of the estimated 120 total units were cased in yellow gold. Early examples feature cases hand-forged by Jean-Pierre Hagmann, identified by his hallmark on the lug. The dial displays the day, month, leap year, 24-hour cycle, and moon phase. On the secondary market, platinum 3974 models typically command prices between $1,200,000 and $2,000,000 depending on provenance and condition. A notable auction result occurred at Christie’s in 2022, where a platinum specimen with a black dial and Breguet numerals sold for over $2.5 million, reflecting the premium placed on rare dial configurations.
