Cellini 50505-0008— lug 20mm

The lug width of the Rolex Cellini 50505-0008 is 20.00 mm. This measurement represents the distance between the case lugs where the strap attaches. Precise measurement of this parameter is essential when selecting an aftermarket strap to ensure perfect fit without play or difficulty in wearing.

For the Cellini 50505-0008 in rose gold, vegetable-tanned alligator remains the supreme choice. The fine grain texture, natural patina, and controlled lustre respect the case's minimalist essence without competing visually. Shell cordovan represents the ideal alternative for daily wear, offering superior durability and lustre that softens with use. Vegetable-tanned calf leather provides versatility of pairing and predictable ageing.

Strap replacement requires a specialised tool (spring bar tool) to release the elastic pins that fix the strap to the case lugs. At Casati Milano, the change is performed in the atelier under supervision to prevent case scratches. If you prefer independence, our team provides step-by-step instructions and necessary tooling. We always recommend working on a padded surface with adequate lighting.

Yes, provided the strap has been manufactured with a 20.00 mm lug width. High-quality aftermarket straps (such as those from Casati Milano) are fully compatible and often offer customisation options impossible with original straps. It is important to verify that the lug is cut to precise measurement and that the shoulders are slightly rounded to adapt to the case geometry.

Leather strap durability depends on wear intensity, climatic conditions, and tanning quality. Alligator or vegetable-tanned shell cordovan resists 18–36 months of daily wear, whilst standard calf achieves 12–24 months. Leather absorbs moisture and sweat, accelerating fibre oxidation. Casati Milano provides an 18-month warranty against manufacturing defects; contact wear is predictable and not covered. We recommend rotating with alternative straps to extend the life of each.
