FAQ

What is the exact lug width of the Patek Philippe Complications 5326G-001?

The lug width of the Patek Philippe Complications 5326G-001 is 20 mm. This measurement should be verified with a digital calliper positioned perpendicular to the lug shoulders. It is critical for ordering compatible straps online, as an incorrect measurement risks misalignment of the buckle or inability to fit within the lugs.

Which strap material is recommended for the 5326G-001?

For the 5326G-001 in 18K white gold, we recommend alligator (fine grain and scaled texture), calf leather with vegetable tanning (which ages harmoniously with the metal), or shell cordovan for those seeking supreme tactile density. Alligator maintains a formal language, whilst naturally tanned calf creates a patina that evolves in harmony with the gold.

How do I change the strap on a Patek Philippe Complications watch?

Strap replacement requires specialised tools (spring bar or small hammer and pin). We recommend against performing this operation without experience, as the white gold case is sensitive to scratches. The Casati Milano service performs this operation in-house, with quality control and a guarantee on the mounting.

Can I use an aftermarket strap compatible with the 5326G-001?

Yes, provided it strictly adheres to the 20 mm measurement according to ISO 1623 standard (±0.2 mm tolerance). Milanostraps.it artisanal straps are calibrated to this standard and guaranteed for 18 months against manufacturing defects. Always verify compatibility with your authorised dealer before purchase.

How long does a natural leather strap last on a watch worn daily?

A high-quality leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 3-5 years with daily wear, depending on perspiration, humidity, and sun exposure. The patina that forms is an aesthetic characteristic, not a defect. We recommend rotating between multiple straps to extend the life of each, and periodic maintenance with specialist leather creams.
