Strap for Cellini Prince White Gold / Black

The lug width of the Rolex Cellini 5443/9-0002 is 20 millimetres, measured centre to centre between the two spring bars. This dimension requires straps specifically constructed for this size, as it is not a standard width like 18 or 22 millimetres.

Alligator is the most natural choice for the Cellini in white gold, thanks to its symmetrical grain and ability to age with character. Hammered calf also represents a contemporary alternative, as does shell cordovan for those seeking a dense and luminous leather. The choice depends on personal style and intended usage.

Changing the strap requires the use of specialised spring bar tools to avoid damaging the white gold case. Position the tool gently beneath the metal pin, lift the internal spring, remove the pin and replace the strap. When in doubt, consult a certified watchmaker or a specialised atelier such as Casati Milano.

Yes, provided the strap is constructed specifically for a 20-millimetre lug width and respects the proportions of the case (32 mm diameter). An artisanal strap of high quality, such as those offered by Milano Straps, guarantees both technical and aesthetic compatibility with the timepiece.

The lifespan of a leather strap depends on the material, climate and intensity of use. High-quality alligator can last 3-5 years under normal conditions, whilst hammered calf tends to have a slightly shorter lifespan (2-4 years). With proper maintenance and protection from excessive humidity, strap longevity increases significantly.
