FAQ

What is the lug width of the Patek Philippe Complications 5960R-012?

The lug width of the Patek Philippe Complications 5960R-012 is 20 millimetres. This standard measurement allows the use of any artisanal strap compatible with this width, ensuring a perfect fit between the lugs of the rose gold case.

Which strap is most suitable for the Patek Philippe Complications 5960R-012?

For the 5960R-012, we recommend materials that respect the watch's hybrid character: black or anthracite alligator for chromatic continuity with the dial, or burgundy shell cordovan for a warm contrast that enhances the rose gold. Aniline calf with vegetable tanning is ideal if you prefer a strap that adapts quickly to your wrist.

How do I change the strap on the Patek Philippe Complications 5960R-012?

The change is performed via spring bars located in the lateral seats of the case, accessible from the caseback. With a dedicated tool (spring bar tool), gently push the bar inward, remove the old strap and seat the new one in the lug holes. It is advisable to have the operation performed by a professional watchmaker to avoid damage to the case.

Can I fit an aftermarket strap on this watch?

Yes, absolutely. The 5960R-012 accepts artisanal quality straps with 20mm lug width. We recommend contacting specialist producers such as Casati Milano, who guarantee constructive quality, precise finishes and verified compatibility. A good aftermarket strap does not compromise the watch's value; often it enhances it.

How long does a natural leather strap last on a watch like the 5960R-012?

Durability depends on use and leather type. Alligator and shell cordovan with proper finishes last 3-5 years with moderate daily use. Aniline calf, being more absorbent, may require replacement after 2-3 years. Proper maintenance — drying after accidental wetting and conditioning with specific creams — significantly extends longevity.
