Full-Cataloguing
Patek Philippe is widely regarded as the pioneer in the field of perpetual calendar chronograph wristwatches, having been the first manufacturer in the world to introduce this groundbreaking complication with the legendary reference 1518 in the late 1940s. A few years later, the firm followed up with the iconic reference 2499, a model that collectors have since dubbed “the perfect wristwatch.” In 1986, Patek Philippe retired the reference 2499 and introduced its successor, the reference 3970. This new reference retained much of the aesthetic charm of its predecessor but featured a significant technical update: the movement was now based on a Lemania ébauche, replacing the Valjoux-based caliber of earlier models. The reference 3970 also introduced a slightly smaller case diameter of 36mm, offering a more contemporary and wearable size. Produced over a span of 20 years, the reference was divided into three distinct series, each with subtle yet meaningful updates.
First series (1986 – 1988) – Features a solid snap back case for ref. 3970 and snap on sapphire caseback for ref. 3971, feuille hands and rectangular indexes. Only produced in yellow gold with an estimated 100 examples produced.
Second series (1987 – 1990) – Features a solid screw back case “E – Etanche”, feuille hands and baton indexes. Hallmarks on the side of the lugs. Produced in all four case materials with an estimated 650 examples produced across all metals. Ref 3971 contunued up to the second series (the present example)
Third series (1989 – 1995) – Features a solid screw back case “E – Etanche” and an additional sapphire caseback, baton hands and lapidated indexes. Estimated 1,350 examples produced across all metals.
