The ladies' chronograph presented by Patek Philippe for 2018 is one of just three references for ladies out of a total of 14 new watches in the collection this year. It replaces the Ref. 7071, which was the brand's first ladies' chronograph, launched in 2009, and is still the only ladies’ chronograph in the Patek Philippe collection. The original model was presented in a cushion-shaped case and marked the introduction of Patek Philippe's first in-house manual chronograph movement, the CH 29-535 PS, to replace the venerable Lemania CH 27-70 calibre that the company had been using in its chronographs for a couple of decades. This movement has a column wheel and horizontal clutch and introduced six patented innovations [see below].
