The Patek Philippe reference 7071 is one of the manufacture's most significant Ladies' Chronograph models, combining elegant proportions with a sophisticated mechanical chronograph movement. Introduced in 2009, the 7071 was the first ladies' chronograph in Patek Philippe's modern collection, housed in a refined tonneau-shaped case inspired by the Gondolo line. Powered by the manually wound Calibre CH 27-525 PS, based on the renowned Lemania architecture and extensively refined to Patek Philippe's exacting standards, the watch features a classic two-register chronograph layout with small seconds and a 30-minute counter, delivering exceptional mechanical performance and timeless aesthetics. Produced in white gold and rose gold, with a variety of dial finishes and diamond-set bezel options throughout its production, the 7071 has become one of Patek Philippe's most desirable ladies' complications, admired for its graceful proportions, exceptional movement and successful combination of haute horlogerie with feminine elegance.
