It houses the certified chronometer caliber 324 S C movement.

Made to Measure

The strap for this watch is made to measure

On the Patek Philippe Twenty~4 the bracelet is drawn as part of the case: no catalogue strap will fit. In the atelier we take the measurements on the watch itself and build the strap on the piece — that is the work of Casati Milano.

FAQ

What is the lug width of the Patek Philippe Twenty~4 7300/1200R-001?

The Patek Philippe Twenty~4 7300/1200R-001 features a lug width of 16 millimetres. This measurement, also referred to as strap width at the lug, determines the width of the strap band that inserts into the case lugs. A compatible strap must measure exactly 16mm to ensure a perfect fit without play or strain.

Which strap is most suitable for the Patek Philippe Twenty~4 7300/1200R-001?

For the Patek Philippe Twenty~4 7300/1200R-001 in 18-carat rose gold, alligator leather straps in black or cognac are recommended for formal occasions, whilst Hermès calf leather in sand or brown tones suits daily wear. A black alligator strap creates a sophisticated contrast with the rose gold case, whereas cognac calf intensifies the warm undertones. For greater versatility, a cotton jacquard NATO in military grey enables swift transitions between formal and casual contexts.

How do you change the strap on a Patek Philippe Twenty~4 7300/1200R-001?

The strap on the Patek Philippe Twenty~4 7300/1200R-001 is removed using a spring bar remover tool, which allows you to release the internal spring that secures the strap to the case lugs. Insert the flat end of the tool between the lug and the strap, gently push towards the case centre, and the strap will disengage. Proceed with caution to avoid scratching the rose gold case. Consult a professional if you are unfamiliar with the procedure.

Does the Patek Philippe Twenty~4 7300/1200R-001 accept aftermarket straps?

Yes, the Patek Philippe Twenty~4 7300/1200R-001 accepts aftermarket straps compatible with the 16-millimetre lug width. High-quality leather straps (alligator, calf, shell cordovan) as well as NATO and rubber options are available online and through specialist ateliers, all guaranteed for mechanical compatibility. Milanostraps.it offers a comprehensive selection of 16mm straps, alongside the bespoke Casati Milano service with personalised consultancy.

How long does a leather strap last on a Patek Philippe ladies' watch such as the 7300/1200R-001?

A quality leather strap (alligator, calf, shell cordovan) on a Patek Philippe Twenty~4 typically lasts 3 to 5 years with moderate daily use, depending on sun exposure, humidity, and maintenance. Well-treated leather with appropriate conditioning products can achieve 6 to 7 years of useful life. Casati Milano guarantees 18 months against manufacturing defects, whilst strap replacement poses no risk to the case: it is a straightforward operation that indefinitely extends the watch's lifespan.
