Strap for Day-Date 36 Yellow Gold Domed President Mother of Pearl Diamonds

The Rolex Day-Date 36 reference 118208-0061 features a 36 mm case with a lug width of 20 mm. This measurement is taken with a millimetre calliper positioned between the two lugs at the narrowest point where the strap meets the case. Any 20 mm strap with straight or slightly tapered ends will be compatible with this reference.

For the Day-Date 36 in 18-carat yellow gold, the most fitting choice is a vegetable-tanned alligator strap in cognac, honey brown, or bottle green. The natural scale texture creates a dialogue of noble materials with the gold case, whilst vegetable tanning develops a patina over time that enhances rather than degrades the strap. Shell cordovan and smooth box-calf leather are refined alternatives whose compact grain complements the polished finishing of the case.

The strap on the Rolex Day-Date 36 is secured to the case via spring bars with a diameter of approximately 1.8 mm. To replace the strap, a fork-type spring bar tool is required to compress and release the spring bars from the lug holes. Care must be taken to avoid scratching the gold lugs: place a soft cloth beneath the case during the operation, and consider entrusting the task to a specialist watchmaker or strap atelier if unfamiliar with the process.

Yes. The Day-Date 36 accepts any standard aftermarket strap in 20 mm width. Milanostraps.it offers a curated selection of handcrafted straps in alligator, calf leather, shell cordovan, and rubber, all specifically suited to the 20 mm lug width of this model. Casati Milano additionally provides a bespoke service including in-atelier leather selection and choice of buckle or deployant clasp in various metals, including gold vermeil to match the yellow gold case.

The lifespan of a leather strap depends on the material, tanning method, and daily usage. A high-quality vegetable-tanned alligator strap, maintained with regular conditioning cream and rotated with other straps, can last between three and seven years whilst retaining its aesthetic and structural integrity. Shell cordovan, owing to its dense fibrous structure, tends to last longer and develops an increasingly attractive patina. Smooth calf leather has a shorter average lifespan when regularly exposed to perspiration and moisture.
