Ladies Chronograph Ref. 7150/250R-001

In 2009, Patek Philippe introduced a chronograph specifically for women that was driven by the Genevan brand's first in-house chronograph calibre with a classic column wheel plus horizontal clutch architecture and manual winding. The aptly-named Ladies First Chronograph Ref. 7071 remained in production until 2016. This year, Patek Philippe has given it a new face, with a 38mm round case instead of the previous cushion shape and a row of 72 diamonds around the bezel. The movement inside this vintage-inspired chronograph is the manual-wind CH 29-535 PS featuring an instantaneous 30-minute counter. It too has a classical architecture... which hasn't prevented the brand from incorporating six patented innovations.
