  in 1986 as a replacement for the iconic reference 2499. While maintaining
  the signature aesthetics found in both reference 1518 and 2499 the refere
 nce 3970 used a Lemania based ebauch as opposed to the previous Valjoux mo
 vement. These models also had a leap year and 24 hour indication for the f
 irst time. The reference was produced in yellow gold\, pink gold\, white g
 old and platinum across a total of four series with production spanning ov
 er 19 years. It is estimated that throughout its course of production over
  4\,000 examples of the reference were produced.\n\nFirst series (1986–1
 988): Snap back case\, feuille hands\, and rectangular hour indexes. Only 
 produced in yellow gold\, with approximately 100 examples made.\n\nSecond 
 series (1987–1990): Solid screw-back case (“E – Étanche”)\, feuil
 le hands\, and baton indexes. Produced across all four metals\, with rough
 ly 450 examples in total.\n\nThird series (1989–1995): Solid screw-back 
 case (“E – Étanche”) with an additional sapphire display back\, bat
 on hands\, and faceted (lapidated) hour markers. Approximately 1\,350 exam
 ples produced across all metals.\n\nFourth series (1994–2004): Maintains
  the configuration of the third series\, though the movement and case seri
 al ranges change. From 1997 onward\, a deployant clasp was introduced. Aro
 und 2\,000 examples are estimated to have been produced.\n\nThe watch\, wi
 th a movement number anchored in the late second series\, comes with speci
 fic elements that make it a transitional piece. At first glance\, the pres
 ent lot appears to feature a third-series dial\, evident in its pointed ba
 ton hands and faceted hour markers. Upon closer examination\, however\, a 
 dot between “31” and “1” on the date track which is characteristic
  of first and second series dials\, reveals a transitional nature. Moreove
 r\, both the case and movement numbers on this piece align with those of a
  second series watch. These transitional examples also have a two-tone col
 oring effect on the the 24-hour subdial\, likely an intentional choice dur
 ing production: the “nighttime” half is varnished a shade darker than 
 the “daytime” portion. A similar example\, sold in the April 24th 2025
  Sotheby’s Hong Kong Important Watches I sale (lot 2273)\, shares the sa
 me transitional dial and bears the case number 2’873’815—only 22 num
 bers apart from the present watch.\n\nOffered directly from the original o
 wner\, this example is accompanied by its original presentation box\, addi
 tional solid case back\, and setting pin. A superb opportunity for the dis
 cerning Patek Philippe collector who values the nuance and subtle evolutio
 n of one of the manufacture’s most celebrated perpetual calendar chronog
 raphs.\n\nPlease note that this lot includes endangered species\, which wi
 ll require a CITES permit for export. Please refer to the Guide for Buyers
  at Auction and Conditions of Business for Buyers for additional informati
 on.
