FAQ

What is the lug width of the Rolex Cellini 50515-0009?

The Rolex Cellini 50515-0009 features a lug width of 20 millimetres. This measurement is model-specific and essential for selecting a compatible strap. The correct measurement is taken internally between the two metal pins projecting from the case.

What strap is most suitable for the Rolex Cellini 50515-0009?

For the Cellini 50515-0009, straps crafted from black or dark brown alligator represent the ideal choice, offering understated elegance and aesthetic compatibility with the rose gold case.

The choice depends on usage context and personal preferences regarding patina development over time.

How do I change the strap on the Rolex Cellini 50515-0009?

Strap replacement involves removing the two pins (or bars) that connect the strap to the case lugs. It is advisable to entrust this task to a professional watchmaker to prevent damage to the case. Casati Milano can provide guidance on correct installation of the new 20mm strap.

Can I use an aftermarket compatible strap with the Rolex Cellini 50515-0009?

Yes, it is entirely possible to use high-quality aftermarket straps with the Cellini 50515-0009, provided they feature an exactly 20-millimetre lug width.

How long does a leather strap last on the Rolex Cellini 50515-0009?

The lifespan of a leather strap for the Cellini 50515-0009 depends on material quality, frequency of wear, and maintenance.
