Patek Philippe
Gondolo 5111R-001— lug 20mm

The lug width of the Patek Philippe Gondolo 5111R-001 is 20 millimetres. This measurement determines the strap width at the point of attachment to the case lugs. To verify the compatibility of an aftermarket strap, measure the internal distance between the two lugs: it must be exactly 20 millimetres. This is the standard specification for medium-small diameter watches such as the Gondolo.

For the Gondolo 5111R-001 in 18-carat rose gold, straps in noble leather are recommended. Alligator represents the choice most aligned with Patek Philippe's heritage: the regular pattern of shields enhances the jewellery-like character of the case. Vegetable-tanned calf offers a sophisticated alternative, whilst shell cordovan guarantees superior resistance over time. Rubber or technical textile straps are not advisable, as they would create visual dissonance with the geometric elegance of the case.

Changing the strap on the Gondolo 5111R-001 requires the use of a springbar tool (an implement with two concave or hooked ends). Position the tool on one end of the springbar (the mobile metal bar that holds the strap), compress it towards the case centre and slide the strap outward. Repeat the operation on the other lug. When inserting the new strap, compress the springbar again and slide the strap into the opening. Work carefully to avoid damaging the rose gold case.

Any strap with a lug width of 20 millimetres is compatible with the Gondolo 5111R-001. Custom-made artisanal straps guarantee maximum compatibility and the ability to personalise colour, material (alligator, calf, shell cordovan) and clasp type (standard, rose gold deployante). Compatibility depends exclusively on the width measured at the point of attachment to the lugs.

The lifespan of a leather strap depends on the quality of the material and frequency of use. A high-quality alligator or calf, with vegetable tanning, typically lasts 5-7 years of moderate to occasional use. Shell cordovan, thanks to the crystalline structure of the fibre, can exceed 10 years. The natural oxidation of noble leather (patina) is a positive process that testifies to the watch's usage. Casati Milano artisanal straps include an 18-month warranty against manufacturing defects.
