Introduced in 1986, the ref. 3970 succeeded the long-standing ref. 2499, marking a new chapter in Patek Philippe’s lineage of perpetual calendar chronographs. This model was powered by the upgraded Lemania-based caliber CH 27-70 Q, replacing the Valjoux-derived movement found in its predecessor. While preserving the family’s timeless aesthetic, the ref. 3970 featured a more contemporary profile, reduced to 36mm in diameter. Produced for nearly two decades across four series and in all four precious metals—yellow, pink, and white gold, as well as platinum—approximately 4,000 examples were made in total.
The present ref. 3970E in platinum belongs to the fourth series, placing it among the first examples produced as the movement number of this series starts from 3’045’XXX. This iteration is notable for its semi-glossy black dial with chaton-set diamond hour markers, adding a luxurious twist to the classic design. In contrast to the more prevalent silvered opaline dials, this configuration imparts visual depth and elegance. The hallmarks are stamped on the sides of the lugs, a detail highly valued by collectors of the ref. 3970.
Offered in well-preserved condition and accompanied by the presentation box and original Certificate of Origin, the accompanying Extract of the Archives also confirms the date code (PESR – March 1996) on the certificate, ensuring its originality. This fresh-to-the-market timepiece is an ideal acquisition for those who appreciate Patek Philippe’s horological excellence with a touch of opulence.
