Lot Essay
This endangered species strap is shown for display purposes only and is not for sale. The watch will be supplied with a calf leather strap.
Consigned by a Private European Collector the present ref. 3970EJ has never been offered in public before and is preserved in very good overall condition.
Reference 3970
In 1986, Patek Philippe launched a new generation of the perpetual calendar chronograph wristwatch, designated reference 3970, replacing the hugely successful reference 2499 in production in four different series from 1951 to 1985. The main difference in the movement was the arrival of the new Lemania based ébauche which replaced the Valjoux movement used for the previous 50 years.
Starting with movement number 875'000, the first series of reference 3970 was produced with a solid snap on back, comprising approximately 100 examples. The second series introduced a solid screw back, designated reference 3970E (E for étanche, French for waterproof). A small number of watches from both series were also available with a sapphire crystal back, designated reference 3971E.
In 1994, a third and last series of ref. 3970 was launched, fitted with a solid screw back as well as an additional sapphire crystal display screw back.
Reference 3970 was discontinued in 2004 and replaced by reference 5970.
While production of the reference 3970/3971 may have ended fourteen years ago, these modern yet classic perpetual calendar chronographs have become a must-have for the discerning collector of complicated wristwatches.
Reference 3970 and calibre 27-70 Q are illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, pp. 305 – 308.
