Strap for World Time 7130 White Gold / Brown

The lug width of the Patek Philippe Complications 7130G-010 is 20 millimetres. This measurement is taken from the inside of one lug attachment to the inside of the opposite lug attachment on the 36-millimetre white gold case, excluding the length of the spring bars. A common mistake is to measure from outside to outside, which would result in an inaccurate reading of 2-3 millimetres larger.

American alligator leather with vegetable tanning represents the most coherent solution aligned with the segmented aesthetic identity of the timepiece. The regular grain and natural finish of alligator leather respect the minimalist formality of the white gold case. Shell cordovan constitutes a richer alternative, ideal for those seeking a patina that develops over time. Vegetable-tanned calf leather offers a softer, more contemporary appearance, whilst natural rubber modernises the watch for a sport-elegant context.

Strap replacement requires the use of a specialist tool: a spring bar remover. Position the watch on a soft surface, orient the small fork of the extractor beneath the spring bar (from the side opposite the case attachment), apply gentle downward pressure to compress the internal spring, and simultaneously pull the strap outward. Repeat for both attachments. Reverse the procedure when mounting the new strap, ensuring both spring bars are fully seated in their housings.

Yes, an aftermarket strap with a 20-millimetre lug width is completely compatible with the Patek Philippe Complications 7130G-010. The critical requirement is to verify that the width is genuinely 20 millimetres (measured inside-to-inside of the lugs) and that the spring bars are standard gauge. We recommend superior-quality leathers — alligator, shell cordovan, vegetable-tanned calf — to preserve the aesthetic and functional value of the timepiece.

The lifespan of a leather strap depends on the type of leather, frequency of use, and environmental conditions. A quality sartorial alligator strap with vegetable tanning maintains structural integrity for 5-7 years under normal use. Shell cordovan, being more resistant, may last 7-10 years. Vegetable-tanned calf leather, more delicate, typically exhibits visible wear after 3-5 years. Prolonged exposure to humidity, direct sunlight, and perspiration accelerates deterioration. Periodic maintenance — gentle cleaning, conditioning with specialist creams — significantly extends the usable life of the strap.
