Patek Philippe
Complications 5180/1G-010— lug 20mm

The lug width of the Patek Philippe Complications 5180/1G-010 is 20 millimetres. This measurement is the internal distance between the two lugs that support the strap on the white gold case. To verify it, remove the current strap and measure precisely between the two lugs: this is the exact dimension you need to seek in any replacement strap to guarantee mechanical compatibility and aesthetic harmony.

African alligator is the most natural choice for the Complications 5180/1G-010 paired with white gold: the regular scale texture and the patina that develops over time integrate perfectly with the case. Alternatively, artisanal French calf leather offers elegant softness, whilst shell cordovan on a white gold deployante clasp creates a contemporary effect. We advise against rubber, which does not provide the tactile richness that a skeletonised timepiece deserves.

Strap replacement requires care. Use a dedicated spring bar tool to gently compress the pins that secure the strap to the lugs. Always work from the outside inward, without excessive force to avoid scratching the white gold. If you are inexperienced, strap replacement can be performed by a professional watchmaker. Once the old strap is removed, measure the new lug width: it must be exactly 20 millimetres to fit correctly.

Yes, the Complications 5180/1G-010 is fully compatible with high-quality artisanal aftermarket straps, provided the lug width is strictly 20 millimetres. Manufacturers such as Casati Milano, which produces in Italy with certified leathers (alligator, calf, shell cordovan), guarantee a construction standard worthy of the timepiece. Always verify that the strap has lugs and a buckle in white gold or at least stainless steel, for consistency with the case.

A high-quality natural leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years with daily use, if properly maintained. Buckle wear (mechanical stress) and the natural ageing of leather are factors that will shorten service life. Artisanal straps such as those from Casati Milano are supplied with an 18-month warranty against manufacturing defects. To extend durability, avoid prolonged exposure to water, perspiration and direct heat sources; clean occasionally with a soft cloth and store in a cool, dry place.
