Patek Philippe’s new Twenty~4 watch boasts an impressive perpetual calendar complication

There’s a new movement sweeping through town in the form of Patek Philippe’s latest watch in its Twenty~4 collection.

Founded in 1839, the storied brand is the only remaining family-owned independent manufacturer in Geneva.

Patek has a global reputation for producing exceptional timepieces, and its latest Twenty~4 watch is no exception. 

The new 7340/1R is the first watch with complications in the Twenty~4 collection.

And it’s no “ordinary” complication but a perpetual calendar — one of the most complex mechanical watch movements in existence. The 18-karat rose-gold timepiece features Patek’s famed ultra-thin, self-winding 240 Q caliber, which measures just 3.88 millimeters high, offering a low profile of 9.95 millimeters on the wrist.

The 7340/1R’s day-date-month perpetual calendar takes into account the varying lengths of months, including leap years.

In addition to the calendar, the watch features a moonphase (visible through an aperture at the 6 o’clock position) and a 24-hour indicator. 

The 7340/1R is also the first round-cased Twenty~4 that is not gem-set, allowing for a more sleek, subtle look while not drawing attention away from the dial. But Patek did not sacrifice comfort or beauty for the new 36 mm timepiece. 

Its polished gold bracelet features central links flanked by more narrow outer links, allowing it to seamlessly conform to the wrist. The watch comes in a choice of two dials: a silver-colored version featuring horizontal and vertical brushing that resembles silk shantung, and an olive green-dial version with an understated sunburst finish emanating from its center. The beauty of the watch’s exquisitely finished automatic movement is visible through its sapphire crystal caseback. 

The Twenty~4 collection, Patek’s only watch line dedicated exclusively to women, was first introduced in 1999. It was designed to fit into all aspects of a woman’s daily life “for every hour of the day and night, at work, at home and during leisure activities,” according to the brand. 

The Twenty~4 has seen many iterations throughout its 26-year history. The first offerings featured a steel manchette bracelet with a diamond-studded bezel and a quartz movement, with a rose-gold version added a year later. While the original watch was rectangular in shape, a round case shape was added to the collection in 2018, featuring an automatically wound mechanical movement for the first time. 

“The timeless design of the Twenty~4 has established itself as a modern classic,” says Patek Philippe president Thierry Stern. With the addition of a perpetual calendar to its lineup, the collection is poised to stand the test of time, 24-7-365.
