Strap for World Time 5130

The lug width of the Patek Philippe Complications Ref. 5130P-020 is 20mm. This measurement is fixed and corresponds to the distance between the lugs of the platinum case. A compatible strap must present a passant (keeper) of exactly 20mm to ensure proper fit without play or compression on the lugs.

Alligator remains the most refined and authentic choice for this timepiece: its regular texture and natural softness enhance the platinum case without competing with it. Alternatively, vegetable-tanned calf leather with pronounced grain offers a more contemporary character, whilst vegetable tanning permits a natural patina that accompanies the watch's ageing. Rubber is recommended only for occasional sports-oriented wear.

Strap replacement requires specific tools: a spring bar tool and a flat, well-lit work surface. Position the watch with the lugs facing upward, gently insert the tool tip into the spring bar slot, push downward to release the old passant, and repeat on the opposite side. Reverse the procedure to mount the new strap. If you lack the proper tool, professional assistance is strongly advised, as imprecise execution may scratch the platinum case.

Yes, provided the strap is purpose-made for the 20mm lug width and constructed from comparable materials (alligator, superior calf leather, certified technical rubber). A poorly manufactured aftermarket strap or one with miscalibrated passants would compromise both aesthetics and functionality. We recommend selecting specialist artisans who guarantee precise measurements and impeccable finishing.

A high-quality leather strap, whether alligator or vegetable-tanned calf, maintains full functionality and aesthetic appeal for 4–6 years of daily wear, depending on environmental exposure and humidity levels. Leather is a living material that adapts to the wrist and develops patina, but inevitably experiences wear. Proper maintenance—protection from intense rain and prolonged direct sunlight—significantly extends longevity. Technical rubber straps typically last 2–3 years.
