Strap for World Time 5131 Rose Gold / Earth

The Patek Philippe Complications 5131R-011 features a lug width of 20mm. This measurement is standard for models in the Complications family and is compatible with any strap crafted for this dimension. To verify the lug width, simply measure the distance between the two holes where the spring bars are inserted on the inner side of the case.

For the Complications 5131R-011 in rose gold with a cloisonné dial, we recommend a mahogany-brown alligator strap or a vegetable-tanned calf leather strap. Alligator offers an elegant grain that harmonizes with the patina of rose gold, whilst vegetable-tanned calf provides superior structural rigidity and an even more fascinating ageing patina over time.

The original rose gold strap on the Patek Philippe 5131R-011 is removed by extracting the spring bars using a dedicated spring bar remover tool inserted into the lateral holes of the case. Once the spring bars are removed, the old strap slides out easily. Installation of the new strap is performed by reversing the procedure: insert the spring bars into the lugs until you hear a click. If you are inexperienced, we recommend contacting a specialised service centre.

Yes, any strap with a 20mm lug width is compatible with the Patek Philippe Complications 5131R-011. However, it is essential that the strap is crafted with materials and finishes worthy of a timepiece in this category: we recommend premium leathers such as alligator, vegetable-tanned calf, or shell cordovan, manufactured by artisans specialising in luxury watchmaking.

A premium leather strap crafted by hand has an average lifespan of 5-7 years with daily wear, varying depending on the tanning method and maintenance. Leather tanned with vegetable tannins has superior longevity compared to modern tanning methods, as it hardens gradually over time, creating a protective patina. Alligator and shell cordovan are particularly durable and improve aesthetically with ageing.
