Patek Philippe
Complications 5170R-001— lug 20mm

The lug width of the Patek Philippe Complications 5170R-001 is 20 mm. This measurement is taken from the inner wall of one lug to the other, at the midpoint of the case. Simply measure the space between the lugs with a digital calliper to verify the compatibility of any aftermarket strap.

For a chronograph of this calibre, alligator leather represents the most orthodox choice, particularly in light brown or dark brown shades. An alternative is vegetable-tanned calf leather, which develops a fascinating patina over time. For those prioritising durability, gummed calf with internal rubber lining provides increased resistance to moisture.

Strap replacement requires extraction of the lug pins using a specific removal tool with calibrated diameter. We recommend performing this operation with extreme care or entrusting the task to a qualified watchmaker to avoid damaging the components. The new strap must measure 20 mm in width for precise insertion.

Yes, any strap manufactured to the 20 mm lug width specification is compatible with the 5170R-001, provided that manufacturing tolerances are below 0.3 mm. Choose high-quality materials (alligator, vegetable-tanned calf) to ensure durability comparable to that of the watch itself.

A high-quality leather strap (alligator or vegetable-tanned calf) has an average lifespan of 4–6 years with moderate daily wear. Longevity depends on exposure to moisture, perspiration and ultraviolet light. A gummed calf strap offers greater resistance, reaching 7–8 years. Periodic maintenance with dedicated products significantly extends durability.
