With a lineage tracing back to the legendary 1518 in 1941 and evolving into the iconic 2499 in 1950, Patek Philippe’s perpetual calendar chronographs have been a constant presence in the horological realm. In 1986, the torch was passed to the reference 3970, and its rarer counterpart, the reference 3971, marking a significant shift with a new case size (36 mm) and a new Lemania base ébauche, which replaced the Valjoux movement used for the previous five decades. The presented watch is a very fine example of the reference 3971E, with a very nicely preserved case in yellow-gold, showing deep hallmarks and adorned with an elegant dial configuration. This dial features applied rectangular hour markers (instead of the later baton one) and “feuille” hands, creating a harmonious and timeless design. Day and month windows grace the upper portion, slightly above the Patek signature, while the date surrounds the subdial housing the captivating moon phases display. This reference 3971E stands as a testament to Patek Philippe’s commitment to craftsmanship and innovation. Only a limited number of these models are available, as the series was soon discontinued in 1990, giving way to the third series of reference 3970. The gorgeous yellow-gold case, coupled with the unique dial configuration, makes this watch not just a timekeeping instrument but an icon and a piece of horological history. Accompanied by a Patek Philippe certificate of origin and an extract from the archives, confirming its production in 1990 and subsequent sale on 10th May 1990, this watch is one of the last 3971E and represents a treasure for true enthusiasts and collectors.
