Patek Philippe Grand Complications Ladies First Perpetual Calendar Rose Gold — Silver Opaline Dial | Ref. 7140R-001

The Ladies First Perpetual Calendar was Patek Philippe's declaration that the perpetual calendar — historically a complication reserved for masculine proportions — belongs equally to women who keep equally complex calendars. Reference 7140R-001 makes this argument in 18-carat rose gold, a 40 mm case that wears its diamond bezel with the ease of a watch that has always known it was exceptional. The round case back is solid, the crown screws down, and the automatic movement regulates itself with the discipline of Geneva's finest calibres.

The silver opaline dial is a canvas of light — shifting from pale grey to warm silver depending on the angle, a quality that animates the perpetual calendar displays arranged upon it. Arabic numeral hour markers punctuate the dial with a legibility that honours the complication's functional purpose: this is a watch meant to be read as well as admired. Luminous hands complete the picture, extending the dial's readability into evening hours.

Mounted on an alligator leather strap with a prong buckle and water resistant to 30 metres, the 7140R-001 is offered with box and papers at 43,999 USD. It represents a perpetual calendar that will not require calendar correction until 2100 — a promise made in rose gold and diamonds, and kept by a movement that counts the days with a precision more reliable than almost anything else its wearer will encounter. Some legacies run on batteries. This one runs on craftsmanship.
