Patek Philippe Ref. 7150/250R-001 Ladies’ Chronograph

In 2009, Patek Philippe presented the Ladies First Chronograph Ref. 7071 that was in production until 2016. Equipped with an in-house manufacture-made chronograph movement (column wheel, horizontal clutch, manual winding), this timepiece was exclusively created for feminine wrists.

In 2018, utilizing the same mechanical caliber, the Genevan manufacture presents new Ref. 7150/250R-001, a new chronograph watch especially created for the female clients. The cushion shaped case has been replaced with an elegant, round rose-gold case with a diameter of 38 mm featuring a bezel set with 72 diamonds. Its timelessly sleek design is emphasized by refined vintage-look details such as the fluted and delicately curved strap lugs, the round chronograph pushers with manually guilloched faces, and the gently cambered sapphire-crystal “box” glass.

The silvery opaline dial also combines a contemporary style with classic aesthetics, showcasing sculpted Breguet hour and minute hands in rose gold and a display layout that makes it eminently legible. The pulsimeter scale of the new Ref. 7150/250R-001 respectfully pays tribute to the tradition of classic chronographs that can measure the cadence of an active lifestyle or the slightly increased heart rate of its proud owner.

The compact case accommodates the manually wound caliber CH 29-535 PS movement with an instantaneous 30-minute counter, crowning its classic architecture with six patented innovations. Its lavish finissage can be admired through the box-type sapphire-crystal case back that is slightly chamfered to echo the profile of the rear bezel.

The new Ref. 7150/250R-001 is the only chronograph in Patek Philippe’s watch collection for ladies. It is worn on a shiny mink gray alligator leather strap secured with a rose-gold prong buckle set with 27 diamonds.
