Frequently asked questions

What is the lug width of the Rolex Cellini 50525?

The Rolex Cellini 50525 features a lug width of 20mm, measured centre to centre between the spring bars. This dimension is optimal for maintaining the elegant proportions of the 39mm case. When ordering a strap, always verify it is specifically sized for 20mm to ensure precise fit and visual harmony.

Which strap is recommended for the Cellini 50525?

We recommend alligator in cognac-brown or shell cordovan subjected to vegetable tanning. Natural alligator develops patina over time, creating a fascinating dialogue with the rose gold case. Burgundy shell cordovan evolves into extraordinary plum tonalities. For those seeking formalism, cream vitello conveys impeccable sartorial rigour.

How do you change the strap on a Rolex Cellini 50525?

The strap is changed by extracting the two lateral spring bars that secure it to the case. Use a dedicated spring bar tool to compress the internal component slightly and slide out the worn strap. Insert the new strap by aligning the holes with the lugs, then push the bars back until they click into place. Always verify the strap is exactly 20mm to avoid mechanical play.

Is an aftermarket strap compatible with the Cellini 50525?

Yes, provided it is specifically dimensioned for 20mm lug width. High-quality aftermarket straps—whether alligator, cordovan, or vegetable-tanned vitello—integrate perfectly with the case. Compatibility depends solely on correct width: a 20mm strap enters the original Rolex lugs without effort.

How long does a natural leather strap last on a Cellini?

A leather strap subjected to vegetable tanning, worn daily, maintains structural integrity for 5-8 years. Longevity depends on usage, climate, and maintenance. The strap edge inevitably experiences wear, though this forms part of the patina. Casati Milano guarantees 18 months against manufacturing defects; with ordinary care, the strap evolves elegantly over time.
