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

The lug width of the Day-Date 36 is 20 millimetres. This is the internal distance between the two attachment points on the case where the strap is inserted. It is essential to measure this dimension accurately before ordering an aftermarket strap to ensure perfect compatibility and secure fit. All straps offered by Milanostraps for this size are calibrated precisely to 20mm.

Alligator is the traditional and most elegant choice, as its natural grain texture pairs perfectly with the finish of yellow gold. Shell cordovan is ideal for those who appreciate a more structured leather that develops a rich patina over time. Fine-grained calf leather is the most versatile and understated solution. For formal occasions, choose black or brown alligator; for daily wear, cognac calf or grey taupe; for summer, vulcanised rubber or natural silk.

Strap replacement is a straightforward operation requiring a dedicated tool (spring bar tool). Position the watch with the lugs facing you, gently insert the thin tip of the spring bar tool into the groove beneath the lug, push upward to release the spring bar pin, and slide off the old strap. Repeat the operation in reverse with the new strap, ensuring the pin is fully seated. If you prefer professional assistance, Casati Milano can replace the strap in the workshop during your visit to the atelier.

Yes, a high-quality aftermarket strap is fully compatible, provided it has the correct lug width (20mm) and is crafted from noble materials with artisanal construction. Milanostraps straps are specifically produced for this size, with attention to visual proportions and construction quality. A well-made aftermarket strap allows you to personalise your watch and adapt it to different contexts whilst maintaining its Rolex certification integrity.

Durability depends on the material and usage. A quality alligator or shell cordovan with vegetable tanning typically lasts 5-7 years with moderate daily use. Robust calf leather can reach 8-10 years. The critical factors are exposure to moisture, direct sunlight, and impacts. With proper care—gentle cleaning, drying after water exposure, storage away from direct light—you can extend strap life significantly. Casati Milano offers an 18-month warranty on manufacturing defects and can provide restoration services for worn straps.
