Patek Philippe Twenty~4 Guide: Quartz 4910 vs Automatic 7300

The Patek Philippe Twenty~4 comes in two forms that share a name and little else: the original 4910, a rectangular "manchette" quartz watch launched in 1999 with a diamond-set case, and the 7300, a round 36 mm self-winding watch introduced in 2018 with the calibre 324 S C and a diamond bezel. The quartz 4910 is the least expensive way to buy a new Patek Philippe; the automatic 7300 is a mechanical Patek in a size that suits most wrists. This guide covers the specifications of both, how the two lines differ, the dial and metal options, how they wear, dealer prices in 2026 and what to check before buying. Bizak & Co. sources both to order; the Twenty~4 collection lists the configurations we can seek.

Patek Philippe Twenty~4 specifications: 4910 quartz vs 7300 automatic

Sources: the Patek Philippe collection pages for current specifications and versions, and the Patek Philippe Seal page for the standard applied to the 324 S C and to the quartz calibre E 15 alike.

What is the Twenty~4 manchette 4910?

The 4910 was Patek's first collection designed from the outset for women, and it broke with the house's habits in two ways: it was rectangular, with a cuff-like case that follows the wrist, and it was quartz. Patek argued that a woman who takes the watch off at night and does not want to set it each morning is better served by a quartz movement, and the E 15 calibre is finished and tested to the same seal standard as the mechanical calibres. The case flanks carry two rows of diamonds, the dial has a sunburst finish with applied markers, and the bracelet is integrated. The line was refreshed in 2018, when the 4910/1200A in steel with blue or grey dials and the 4910/1201R in rose gold joined the older 4910/10A. The manchette is small by modern standards, which is exactly why it still sells: it sits like a bracelet and disappears under a cuff.

What changed with the Twenty~4 Automatic 7300?

The 7300, launched in October 2018, answered the most common request from Twenty~4 clients: a mechanical movement. Patek built a round 36 mm case with a diamond-set bezel, put in the calibre 324 S C that also powered the Nautilus 5711 at the time, and gave it a date at 6 and luminous Arabic numerals so it reads as an everyday watch rather than a jewel. The bracelet is integrated but broader than the manchette's, with a fold-over clasp. The first dials were blue and grey sunburst on steel and brown and silvery on rose gold; an olive green dial followed in 2021 on both metals, and diamond pave versions sit at the top of the line. The 7300 is, in effect, Patek's answer to the 33 mm and 36 mm Datejust and the 34 mm Royal Oak: a self-winding watch with the house's finishing in a size most people can wear.

Quartz or automatic Twenty~4: which to choose?

Choose the 4910 if the watch will be worn occasionally, if a small rectangular case is the point, or if the budget is the entry level. Choose the 7300 if the watch will be worn most days, if you want a display back and a movement, or if the wrist is above about 15 cm and a manchette looks too slight. Neither is a bad Patek; they are different objects.

How does the Twenty~4 wear?

The manchette 4910 measures about 25 mm across and 30 mm top to bottom, and because the case has no lugs, it wraps the wrist in the way a cuff bracelet does; it suits wrists from about 13 cm (5.1 inches) upwards and is one of the few luxury watches that does not look oversized on a very slim wrist. The 7300 at 36 mm has short, curved lugs that flow into the bracelet, so it wears a little smaller than a 36 mm watch with conventional lugs; it is comfortable from about 14.5 cm (5.7 inches). Both bracelets are sized by removing links, and both clasps are fold-over with no on-the-fly adjustment. The 7300's luminous numerals make it the more legible of the two at night.

How much is a Patek Philippe Twenty~4? Retail and dealer prices in 2026

• Retail. The steel quartz 4910 is the least expensive watch in Patek's catalogue and has sat in the high teens to low US$20,000s at US retail in recent years; the steel 7300 has sat in the high US$20,000s to low US$30,000s, and rose gold versions considerably higher. The current figures are available from an authorised Patek retailer, and both references are among the most accessible Pateks at retail, with short waits in many markets.
• Secondary market. Through 2025 and 2026 both lines have traded near retail pre-owned, with unworn steel 7300 examples at a small premium in some dial colours and quartz manchettes at a modest discount to retail. There is no Nautilus-style premium here.
• Bizak catalogue asks. On 21 September 2026 our sourced catalogue listed the steel quartz 4910/10A-012 at US$15,787, the 4910/1200A-001 blue at US$20,291 and the 4910/1200A-010 grey at US$23,668; the rose gold 4910/1201R-001 at US$45,360; the steel automatic 7300/1200A-011 olive green at US$26,779; and the rose gold 7300/1200R series at US$49,787 to US$53,559, with the diamond pave 7300/1450R-001 at US$283,764. All are sourced to order.

Is the Twenty~4 a good investment?

It is a watch to wear rather than to trade. Because both lines are obtainable at retail, the secondary market does not pay a premium, and a pre-owned example will usually sell for less than a new one for years. What the Twenty~4 offers instead is stability: it does not fall the way hyped references do after a spike, and a full set in good condition holds a large share of its retail price. If value retention matters, buy the steel 7300 in a standard dial colour, keep the certificate and box, and have it serviced by Patek; if resale is the priority, ask for a written cash-buy assessment before you commit.

Buying a used Twenty~4: what to check

• Certificate of Origin. The case number on the certificate should match the watch; for older manchettes Patek can issue an Extract from the Archives confirming the original configuration.
• Diamonds. Count the stones on the case flanks (4910) or the bezel (7300) and check that every setting is tight and none is chipped; a replaced stone is a Patek job, not a jeweller's.
• Quartz movement (4910). Ask when the battery was last changed and whether the seals were replaced at the time; a watch that has been left with a dead battery for years can suffer leakage.
• Automatic movement (7300). Fully wound, the watch should run through the night; check that the date changes cleanly around midnight and that the rotor spins freely behind the display back.
• Bracelet. Hold the watch by the clasp and look for sag; check that links have not been over-polished so that the satin and polished surfaces blur into each other.
• Case edges. The manchette's case corners and the 7300's lug edges should be crisp; rounded edges mean polishing.
• Price against the band. A full-set Twenty~4 offered well under the market is the single most reliable warning sign.

No. Both the 4910 and the 7300 are rated to about 30 m, which covers rain and hand washing but not swimming or showering.
