Frequently asked questions

What is the lug width of the Patek Philippe Complications ref. 5180/1R-001?

The Patek Philippe Complications ref. 5180/1R-001 features a 20mm lug width. This measurement identifies the internal space between the two lugs that attach the strap to the case. It is essential to verify this dimension before purchasing an aftermarket strap to ensure compatibility and avoid fitting issues.

Which strap is best suited for the Patek Philippe Complications 5180/1R-001?

For the 5180/1R-001, we recommend straps crafted from alligator with vegetable tanning, shell cordovan, or calf leather. Dark cognac alligator and black shell cordovan are the most coherent choices, complementing the Genevan classicism and rose gold case aesthetics. Avoid synthetics: this timepiece deserves material authenticity.

How do you change the strap on this Patek Philippe model?

Strap replacement involves removing the two spring bars that pass through the case lugs. It is recommended to use a dedicated spring bar tool to prevent scratching. If you lack experience, consult a certified watchmaker or contact Casati Milano, which offers strap-changing services with personalised consultation via WhatsApp.

Can I use an aftermarket strap on my Patek Philippe 5180/1R-001?

Yes, compatible aftermarket straps are entirely admissible, provided they respect the 20mm lug width and maintain a maximum thickness of 4.5–5mm. Choose reputable manufacturers such as milanostraps.it or brands specialising in vegetable tanning and premium leathers. A quality strap will not diminish the watch's value.

How long does a leather strap last on a watch like the 5180/1R-001?

A quality leather strap, with vegetable tanning and artisanal craftsmanship, typically lasts 3–5 years with daily wear, extendable to 7–10 years with regular maintenance (gentle cleaning, protection from excessive moisture). Leather naturally develops patina and can be regenerated with specialist treatments. Casati Milano provides an 18-month warranty on manufacturing defects and offers regeneration services.
