Day-Date 36 118205f-0056— lug 20mm

The lug width of the Rolex Day-Date 36 118205f-0056 is 20 mm. This is the exact distance between the lugs where the strap is inserted. It is essential to verify this measurement before purchasing an aftermarket strap, as even slight deviations (19 mm or 21 mm) compromise fit and security.

The traditional strap for the Day-Date 36 is alligator, which combines understated elegance with the natural scale texture. However, shell cordovan offers superior ageing patina, whilst vegetable-tanned leather represents an ethical alternative. For casual wear, a striped NATO or FKM rubber with gold-tone lugs maintain visual harmony with the Everose Gold case.

Strap replacement requires a specialised tool (spring bar tool) to compress the lug springs slightly and extract them from the case. On valuable timepieces like the Day-Date 36, it is advisable to entrust the operation to an expert or use the Casati Milano service, where you will personalise your strap in the atelier following every production phase.

A quality leather strap (alligator, cordovan, calf) typically lasts 3–5 years with daily wear, depending on maintenance and climate conditions. Vegetable-tanned leather ages more visibly but retains structure longer. Milanostraps.it provides an 18-month guarantee on manufacturing defects; to extend durability, we recommend periodic cleaning and storage in dry environments.
