Frequently asked questions

What is the lug width of the Rolex Day-Date 36 118208-0112?

The lug width of the Rolex Day-Date 36 118208-0112 is 20 millimetres. This is the internal distance between the lugs of the case, the precise space where the strap must sit. Accurate measurement is essential to ensure perfect fit and secure mounting without compromising the case proportions.

Which strap is most suitable for the Rolex Day-Date 36 in yellow gold?

For a Day-Date 36 118208-0112 in yellow gold, alligator is the most appropriate formal choice: the fine, uniform grain, natural patina, and flexibility enhance the case elegance. Alternatively, calf leather with vegetable tanning offers rich texture and deep patina development over time, whilst shell cordovan provides superior structural density and longevity. For informal contexts, a rubber strap with texture offers versatility without sacrificing elegance.

How do you change the strap on a Rolex Day-Date 36?

Changing the strap on a 118208-0112 requires a specialist tool for removing the spring bars from the case lugs. It is recommended to consult an authorised service or artisanal strap specialist such as Casati Milano. The operation must be conducted with precision to avoid case damage and ensure proper seating of the new 20mm strap. Casati Milano offers this service by appointment, guiding the entire process via WhatsApp.

Is an aftermarket strap compatible with the Day-Date 36 118208-0112?

Yes, any strap with a 20mm lug width is compatible with the 118208-0112, provided it meets equivalent quality standards. Milanostraps.it straps for the 20mm size offer guaranteed compatibility, maintaining case proportions and construction quality. Avoid inferior quality straps, which could compromise the watch's aesthetics and security.

How long does a leather strap last on a Rolex Day-Date 36 worn daily?

Durability depends on material and usage: quality artisanal alligator typically lasts 3–4 years with daily wear; shell cordovan, owing to its structural density, easily exceeds 5 years; calf with vegetable tanning averages 3–4 years. Wear is not a defect but a characteristic: the patina that develops testifies to time's passage. Casati Milano straps include an 18-month warranty covering manufacturing defects, independent of the leather's aesthetic lifespan.
