Strap for Cellini Time White Gold / Black / Alligator Brown

The lug width of the Rolex Cellini 50509-0022 is exactly 20 millimetres. This measurement represents the internal distance between the two lugs of the case and is essential for selecting a compatible strap. A strap of different width will not fit correctly to the lugs, compromising both the aesthetics and the functionality of the attachment.

For the Cellini 50509-0022, alligator represents the most traditional and coherent choice with the dress character of the watch. Its regular texture, the natural patina that develops over time, and its formal appearance enhance the essentiality of the white gold case. Alternatively, vegetable-tanned calf leather offers immediate comfort whilst maintaining high ceremony, whilst a quality NATO strap permits daily versatility.

To change the strap, position the watch on a soft surface and use a dedicated tool to extract the spring bars (perni) from the lugs. Depress the bar on one side, slide out the old strap and insert the new strap, ensuring that the bar is securely closed. It is advisable to consult a professional to avoid damage to the lugs or spring bars.

Yes, it is entirely possible to use a high-quality aftermarket strap compatible with the 20mm lug width. Ensure that the strap has the correct lug width and that the spring bars are appropriate (typically 1.4–1.5 mm diameter for high-end Rolex straps). Bespoke artisanal straps guarantee the best fit and longevity.

The lifespan of a leather strap depends on the material, usage and maintenance. High-quality alligator typically lasts 5–8 years with moderate use and regular care. Vegetable-tanned calf tends to last 3–5 years, developing a pleasant patina over time. Artisanal straps with warranty on manufacturing defects (such as those from Casati Milano) provide additional protection on build quality.
