Strap for Day-Date 36 Everose Domed / President / Chocolate Diamonds Rubies

The lug width (ansa measurement) of the Rolex Day-Date 36 118205f-0104 is precisely 20 millimetres. This measurement represents the distance between the two internal lugs of the case where the strap is anchored. It is essential to verify this dimension before purchasing an aftermarket strap, as an incorrect lug width (18mm or 22mm) will not fit properly and may cause dangerous movement or mechanical incompatibility.

For the rose gold Day-Date 36, alligator leather represents the most elegant choice due to its naturally fine grain, which dialogues perfectly with the luminosity of rose gold. Alternatively, fine-grained calf leather in dark brown or black offers daily versatility and naturally accelerated patina development. Shell cordovan is a sophisticated choice for those who prioritise density and temporal resistance. Vegetable-tanned leather ensures harmonious ageing with the case gold.

To change the strap, position the watch with the dial facing upward and locate the lateral lugs. Using a springbar tool (flat lever implement), gently lift the springbar (the small internal spring at the lug) and slide the old strap outward. Repeat the operation on the opposite lug. To mount the new strap, align the end with the springbar, press the springbar tool lever to create space, and slide the strap into position. Ensure both sides are securely anchored before wearing the watch.

Yes, any strap with a 20 millimetre lug width is mechanically compatible with the Day-Date 36 118205f-0104. However, we recommend selecting high-quality straps, preferably in noble materials such as alligator, calf or shell cordovan, as a luxury watch deserves a strap of equal standing. Bespoke handcrafted straps guarantee superior aesthetic finish and durability over time compared to mass-produced alternatives.

A high-quality leather strap made from noble materials such as alligator, calf or shell cordovan typically lasts between 3 to 5 years with regular daily use. Longevity depends on factors such as frequency of wear, exposure to moisture, perspiration and sunlight. A vegetable-tanned leather strap develops natural patina over time, becoming visually more interesting. Casati Milano guarantees 18 months against manufacturing defects and recommends keeping the strap dry and stored in a cool environment during periods of non-use.
