Strap for Day-Date 36 White Gold Fluted / Oyster / MOP

The lug width of the Rolex Day-Date 36 reference 118239-0115 is 20 mm. This measurement should be taken internally between the two lugs using a digital calliper, in contact with the case. It is essential to use straps with straight ends, consistent with the lug geometry of this specific model.

For a Day-Date 36 in white gold, alligator belly or hornback leather is the most coherent choice from a stylistic standpoint, owing to its regular grain and suppleness. Alternatively, shell cordovan offers a compact, poreless surface that develops a rich patina over time. A deployant clasp is recommended to ensure even fit and minimise wear on the lugs.

Replacing the strap on a Rolex Day-Date 36 requires a spring bar tool to release the spring bars securing the strap to the lugs. It is advisable to work on a soft surface to prevent scratches on the white gold case. If in doubt, it is preferable to consult a watchmaker or the Casati Milano atelier to avoid any damage to the lugs.

Yes, numerous aftermarket straps are compatible with the Rolex Day-Date 36 118239-0115, provided they feature a 20 mm lug width and straight ends. Milano Straps offers a selection of handcrafted straps in alligator, cordovan and vegetable-tanned leather, available bespoke or online, with buckle or deployant clasp options.

The lifespan of a leather strap depends on the quality of the hide, frequency of use and exposure to perspiration and moisture. A high-quality alligator or cordovan strap, with moderate daily wear, retains its structural and aesthetic integrity for 3 to 5 years. Rotating between multiple straps and avoiding prolonged contact with water will significantly extend the life of the piece.
