Strap for Cosmograph Daytona Everose / Cerachrom / Pink / Oysterflex

The Rolex Daytona 116515LN-0013 has a lug width of 20mm, measured between the inner edges of the two case lugs. This is the standard measurement for the 40mm Daytona family and determines compatibility with any 20mm aftermarket strap.

For the rose gold version with black ceramic bezel, a vegetable-tanned alligator strap in dark brown or burgundy offers the most coherent aesthetic pairing. Box calf leather suits a sportier wear, whilst vulcanised rubber is recommended for aquatic use. The final choice depends on the wearing context and the owner's chromatic preference.

The strap is removed by compressing the spring bars that secure it to the case lugs, using a dedicated spring bar tool with a bifurcated tip. The tool compresses the internal spring, releasing the bar from the lug. Care must be taken to avoid scratching the rose gold lugs; it is advisable to entrust the operation to a watchmaker or a specialist atelier such as Casati Milano.

Yes. Any strap with a 20mm lug width is compatible with the Daytona 116515LN-0013. The aftermarket offers options in alligator, calf leather, shell cordovan, nylon NATO and vulcanised rubber. Milano Straps provides a curated selection of handcrafted 20mm compatible straps, also available in a fully bespoke version through Casati Milano.

The lifespan of a leather strap depends on leather quality, frequency of wear and exposure to moisture and perspiration. A high-quality vegetable-tanned alligator strap, worn on rotation, typically lasts 2 to 4 years before the patina and wear on the buckle hole necessitate replacement. The use of a deployant clasp reduces mechanical stress, extending the strap's service life.
