Frequently asked questions

What is the lug width of the Rolex Day-Date 36 128345RBR-0064?

The lug width of the Rolex Day-Date 36 128345RBR-0064 is 20 millimetres. This measurement refers to the internal spacing between the two lugs (case attachment points) where the strap affixes. Precision to the millimetre is essential to ensure a proper fit and optimal stability of the strap on the case.

Which strap material is recommended for the Day-Date 36 in rose gold?

For the Day-Date 36 in rose gold (128345RBR-0064), alligator leather is the most appropriate choice: its naturally fine grain structure complements the luminosity of rose gold without creating visual competition. Vegetable-tanned calf leather, shell cordovan, and rubber sports straps are equally valid options depending on the context of use and personal preference.

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

Strap replacement requires specialist tools—a spring bar tool and microscopic screwdriver—to extract the small springs from the case lugs. We recommend entrusting this operation to a professional watchmaker or specialised atelier such as Casati Milano to avoid damage to the case or attachment mechanisms.

Can I fit a quality aftermarket strap to this model?

Yes, a quality aftermarket strap can be fitted provided it strictly adheres to the 20-millimetre lug width specification. An artisanal strap from specialised manufacturers often delivers finishing and materials superior to factory-issued straps, further elevating the aesthetic value of the watch.

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

Strap longevity depends on intensity of use, tanning method, and maintenance standards applied. A quality artisanal alligator or shell cordovan strap can endure 5-8 years with regular use and periodic care. Avoiding prolonged exposure to water, humidity, and UV radiation significantly extends lifespan.
