Strap for Day-Date 36 Yellow Gold Diamonds / President / Champagne Roman

The lug width of the Rolex Day-Date 36 reference 118348-0071 is 20 mm. This measurement is taken internally between the two case lugs at the point where the strap is inserted. All compatible straps must feature a 20 mm end with a curved profile to fit correctly against the yellow gold case.

For the Day-Date 36 in yellow gold, an alligator strap with vegetable tanning is the most coherent choice given the character of the watch: the natural grain texture develops a patina that enhances the precious metal. Shell cordovan offers a smooth surface with waxy reflections that are equally refined. For less formal occasions, a soft calf leather strap with contrast saddle stitching provides an elegant sartorial touch.

The strap on the Rolex Day-Date 36 is removed using a springbar tool — a forked-tip instrument that compresses the springbars housed within the lugs. The operation does not require opening the case and can be performed carefully by the owner or entrusted to a watchmaker. Given that the Day-Date lugs are crafted in solid gold, it is strongly advisable to use a protective cloth to avoid scratching the case.

Yes, the aftermarket offers a wide selection of straps compatible with the Rolex Day-Date 36 at a 20 mm lug width. Milano Straps provides handcrafted straps in alligator, calf leather, shell cordovan and rubber, all produced with a curved 20 mm end to ensure a proper fit against the Day-Date lugs. The artisan quality of these straps frequently surpasses that of standard accessories, with full customisation available.

The lifespan of a leather strap depends on material quality, frequency of use and care. A high-quality vegetable-tanned alligator strap, kept away from water and periodically treated with leather conditioner, can last between 3 and 5 years under regular use. Shell cordovan, owing to its dense fibrous structure, often lasts even longer. A standard calf leather strap typically has a useful life of 1 to 3 years. The Casati Milano warranty covers manufacturing defects for 18 months.
