Strap for Day-Date 36 White Gold / Strap / Paved

The Rolex Day-Date 36 118139-0093 features a lug width of 20 millimetres. This is the precise distance between the attachment lugs on the case. It is essential to verify this measurement before ordering an aftermarket strap using a digital calliper, measuring from edge to edge on the lug attachment points. Even a minor error of a few millimetres will result in poor fit and aesthetic compromise.

The ideal strap depends on your daily use. Alligator is the natural aesthetic choice, with fine grain that enhances white gold without visual competition. Vegetable-tanned calf offers versatility and develops a patina over time. Shell cordovan provides chromatic contrast and distinctive texture richness. For intensive use, a high-quality rubber strap with white gold deployante ensures ergonomic comfort and durability. Through Casati Milano, you can personally select the leather at the atelier and follow the crafting process.

Changing the strap requires a spring bar tool to remove the spring bars that attach the strap to the case lugs. Position the watch face-down on a soft surface, insert the spring bar tool into the narrow slot between the strap and case, and gently push to release the spring bar. Remove the old strap and insert the new one by snapping the spring bar into the corresponding slots. If uncertain, consult an official Rolex service centre.

Yes, provided the strap is correctly sized for a 20 millimetre lug width. It is critical that the strap ends (the attachment points to the watch) are precise: even a 0.5 mm variation creates a visible gap between strap and case, compromising aesthetic harmony. Choose an artisan guaranteeing leather quality and precision, such as Casati Milano, which also offers a personalised white gold deployante if you desire an elegant and secure solution.

The lifespan of a leather strap depends on material quality, tanning method, and intensity of use. High-quality alligator with artisanal vegetable tanning can last 5-7 years of daily wear, developing a pleasing patina. French calf, being softer, averages 4-6 years. Shell cordovan, with proper care, can exceed 7 years. Critical factors include exposure to moisture, perspiration, and direct UV rays. A high-quality rubber strap with deployante can last 8-10 years. With Casati Milano you receive an 18-month warranty on manufacturing defects, and can renew your strap with confidence knowing that artisanal quality ensures superior longevity.
