Patek Philippe Twenty~4 (Ref. 7300/1200A)

A cuff for every hour

Patek Philippe launched the Twenty~4 in 1999 as its first collection made only for women. The name was the brief: a watch to wear through all 24 hours of a day. The original was a 'manchette,' or cuff, inspired by the bracelet-watches of the Art Deco period, with a cambered rectangular case flowing into a steel bracelet. It measured 25.1 by 30 mm and 6.8 mm thick, with 36 diamonds set along its sides and a quartz movement, caliber E15.

It came in three steel versions named for their dials: Forever Black (ref. 4910/10A-001), Eternal Grey and Timeless White. At introduction it cost $6,250, or 10,700 German marks. The advertising spoke directly to women with the line 'Who will you be in the next 24 hours?'

It worked. One magazine called the Twenty~4 the most popular women's collection the company had produced for years, and another described it as Patek Philippe's entry-level model and its best-selling women's line. For two decades every Twenty~4 ran on a battery.

Round, mechanical and five years in the making

In October 2018 Thierry Stern introduced the Twenty~4 Automatic himself, at an evening in a glass pavilion built for the occasion beside the company's offices in Milan. He said the watch had taken five years and 40 prototypes. 'We've decided that women should also have their own watches,' he said. 'Not gimmicks, not something that looks like a man's watch.'

The new watch broke three of the collection's habits at once. It was the first Twenty~4 with a mechanical movement, the first with a round case, and the first with a date and center seconds. What tied it to the 1999 cuff was the bracelet, with its cambered center links framed by two-tier outer links, and a new patented fold-over clasp with four independent catches to keep it from opening by accident.

It launched in five versions across three references. The steel 7300/1200A came with a sunburst blue or sunburst gray dial for $26,083. Rose gold versions with a chocolate brown dial or a satin dial meant to evoke Shantung silk cost $45,361, and a fully diamond-set rose gold version, with 469 stones totaling about 1.88 carats, cost $56,702.

What is inside

At launch the Twenty~4 Automatic used caliber 324 S C, a self-winding movement already found in Nautilus, Aquanaut and Calatrava models, beating at 4 Hz with a 21K gold central rotor engraved with the Calatrava cross, visible through the sapphire case back. It was the same caliber used in the steel Nautilus 5711.

The maker's current specification lists caliber 26-330 S C: 27 mm across, 3.59 mm thick, 215 parts, 30 jewels, 35 to 45 hours of power reserve, a 21K gold central rotor, Gyromax balance and Spiromax balance spring, beating at 4 Hz, with the Patek Philippe Seal. The sources consulted do not date the switch from the 324 S C.

How to identify a 7300/1200A

The steel round Twenty~4 is 36 mm across and 10.05 mm thick, water resistant to 30 meters, with a fully polished steel bracelet. Its dial carries applied white gold Arabic numerals and rounded baton hands, both with white luminous coating, plus a date window at 6 o'clock. The bezel holds 160 diamonds in two gently alternating rows, a pattern Patek Philippe calls 'Dentelle,' or lacework. The maker's product page gives their weight as 0.81 carat; its collection page and one magazine give about 0.77 carat.

The last three digits name the dial. The 7300/1200A-001 has a sunburst blue dial and the -010 a sunburst gray, both from the 2018 launch. The -011, with an olive green dial, was added in February 2021 at a US retail price of $27,796, alongside a rose gold 7300/1200R-011 with a tone-on-tone gold dial. Rose gold versions carry the 7300/1200R reference.

The rectangular quartz cuff did not disappear. In 2020 Patek Philippe brought it back as the ref. 4910/1200A, in the original 25.1 by 30 mm proportions but with Arabic numerals like the round model's, at $14,670.

A line that keeps widening

In 2019 Patek Philippe added a snow-set rose gold version, the ref. 7300/1450R-001. Later the collection gained its first complication, the rose gold ref. 7340/1R, a perpetual calendar on the ultra-thin self-winding caliber 240 Q with an olive green dial.

Watch writers' reactions to the round model were mixed. One wrote that the styling might be uninspiring for an enthusiast but ideal for someone who wants a Patek Philippe that is fuss-free, which explains the collection's consistent commercial success. Another called the move to a mechanical movement long overdue.

By October 2026 the steel 7300/1200A-001 listed at $32,884 in the United States, up from $26,083 at its 2018 launch. The collection now offers two distinct cases, the Art Deco cuff with quartz and the round case with a self-winding movement, which Thierry Stern calls a modern classic.

Price record

This is an asking price, not a sale. It is what a seller wanted on the date shown. Asking prices often sit above what buyers pay, but an ask is not a ceiling: a sale can land on either side of it. It is not a value.

By reference price, Patek Philippe Twenty~4 (Ref. 7300/1200A) is number 51 of 100 in the watches entries of the FLOAT 100. 54 of those 100 rest on a realized sale; the rest carry an asking price or a guide value, and each page says which. Rank within the FLOAT 100 itself (40 here) is editorial: how much an object defines its field, not price alone.
