Strap for Calatrava 7122 White Gold / White

The lug width of the Patek Philippe Calatrava 7122/200G-001 is 18 mm. Measured between the inner shoulders of the lugs, this dimension is exceptionally rare in contemporary horology and requires straps specifically manufactured to this specification.

Mississippi alligator leather is the most aesthetically coherent choice with 18-carat white gold: the geometric texture and patina that develops over time amplify the discreet luxury character. Valid alternatives include vegetable-tanned calf in cognac tones, which evolves chromatically, or an FKM rubber strap for sportier applications.

Strap replacement requires specialised tools for bayonet or screw-type lugs, depending on your case configuration. We recommend consulting an authorised Patek Philippe Service Centre or contacting Casati Milano for professional replacement that preserves case integrity. With milanostraps.it you can order your 18mm strap and receive detailed instructions.

Yes, aftermarket straps with an 18mm lug width are fully compatible with the 7122/200G-001. Quality depends exclusively on the manufacturer: Casati Milano crafts artisanal straps in fine leather (alligator, calf, shell cordovan) with manual finishing, delivering results worthy of a Patek Philippe.

A quality alligator or calf strap, worn daily with moderate use, maintains its aesthetic and functional integrity for 8–12 years. Leather ageing is part of a strap's beauty: the patina that forms is not a defect but evolution. Casati Milano guarantees 18 months against manufacturing defects and offers restoration and reconditioning services.
