Patek Philippe
Grand Complications 5016P-012— lug 20mm

The lug width (distance between the lugs) of the Patek Philippe Grand Complications ref. 5016P-012 is 20 mm. This measurement must be verified precisely using a digital caliper before purchasing a strap. A strap with an incorrect lug width will not anchor securely to the lugs and will result in unacceptable lateral play on a watch of this magnitude.

For the Grand Complications 5016P-012 in platinum, the ideal strap is in superior-grade alligator (Alligator mississippiensis with fine grain), or in calf with vegetable tanning or shell cordovan. Dark brown or black alligator enhances the neutral luminosity of platinum and ensures an elegant visual transition. For formal occasions, charcoal black is unmatched; for warmer styling, honey-brown with natural patina echoes the tones of aged platinum. A platinum or white gold deployant clasp completes the choice, facilitating adjustment without stress on the leather.

The strap is changed by removing the spring bars that anchor it to the lugs. You will use a specialized watchmaking tool, preferably a springbar removal plier, to gently compress the spring bars and extract the old strap. Next, insert the new strap by aligning the spring bars with the lugs and allowing them to snap into position. For a Patek Philippe of this importance, we recommend entrusting the operation to a certified watchmaker to avoid damage to the platinum lugs or the new strap.

Yes, it is possible to purchase aftermarket straps compatible with a 20 mm lug width. However, for a Patek Philippe Grand Complications in platinum it is essential to choose straps crafted from noble materials (alligator, shell cordovan, vegetable-tanned calf) and from specialized artisans. milanostraps.it offers a selection of 20 mm artisanal straps; Casati Milano, a Milan-based atelier, also allows you to personally select the leather and customise the project according to your preferences with an 18-month warranty against manufacturing defects.

The lifespan of a leather strap depends on the material, usage, and maintenance. Superior-grade alligator can last 5–8 years with daily wear; shell cordovan 6–10 years thanks to its elevated structural density; vegetable-tanned calf 3–5 years as it is more delicate. Factors such as prolonged sunlight exposure, moisture, and perspiration accelerate ageing. Proper drying after use and occasional cleaning with a soft cloth significantly extend the strap's lifespan.
