Catalogue Essay
The Patek Philippe reference 3970 is a worthy heir to the iconic lineage of Patek Philippe perpetual calendar chronographs, which started in 1941 with reference 1518.
Launched in 1986 and in production until 2004, reference 3970 replaced reference 2499. Both models shared certain features such as pump pushers and down turned stepped lugs. However, reference 3970 presented certain details, enabling it to proudly step into contemporary horology. It replaced the Valjoux movement of its predecessors with a heavily modified Lemania 2310 ébauche dubbed CH 27-70Q. Furthermore, two new indications were added to ref 3970, a leap year indication and a 24 hour hand.
Reference 3970 underwent three significant transformations. While the first series featured a snap on caseback, the second series displayed baton markers, feuille hands and a screw back. It was produced concurrently with reference 3971 which had a snap on sapphire back. Finally the third series merged references 3970 and 3971 and offered two screwed case backs: sapphire and solid.
The present lot, part of the second series of which only 64 are known, is preserved in overall excellent condition and will appeal to the collector looking for a timepiece representing Patek Philippe’s unparalleled history in the field of perpetual calendar chronographs.
