The first numbered Patek Philippe Perpetual Calendar Chronograph ref. 3970 will appear in Sotheby’s Important Watches sale in Geneva on November 8. Originally sold at Patek Philippe’s Geneva salon on January 14, 1987, the watch carries movement no. 875’000 and comes with its original box and certificate of origin.

Why it matters (interpretation): This is a historically important early example of a landmark Patek Philippe complication, and provenance like this can materially influence collector demand and auction pricing. It also highlights how rare, early-production vintage complicated watches continue to migrate back into the market.
