Patek Philippe
Complications 5170G-010— lug 18mm

The lug width of the Patek Philippe 5170G-010 is 18mm. This measurement represents the distance between the two pins that attach the strap to the case. It is important to verify this dimension before ordering a strap, as 18mm is a rarer size compared to 20mm or 22mm, requiring more specialised sourcing.

Strap replacement requires a specialised spring bar tool (pin extractor). Locate the small holes at the ends of the lugs, insert the tool tip to compress the internal spring and release the pin.

Yes, provided the strap is constructed specifically for 18mm lug width. Bespoke artisanal straps, such as those crafted by Casati Milano, are the ideal solution for obtaining personalised finish and material properties whilst respecting the exact specifications of the Patek Philippe case.

Longevity depends on material and usage patterns. High-quality alligator typically lasts 5-7 years with daily wear; vegetable-tanned calf varies from 3-5 years; shell cordovan can reach 7-10 years. Factors such as humidity, sun exposure and maintenance regularity influence lifespan. A bespoke strap with production defect warranty offers additional protection.
