Strap for Day-Date 36 Everose Gold - Fluted / Brown Ombré - Roman / President

The lug width (or strap width) of the Rolex Day-Date 36 128345RBR-0075 is 20 millimetres, measured between the two spring bars that connect the case to the strap. This measurement is the construction standard for the Day-Date in 36mm format and determines which aftermarket straps are compatible with your watch.

For the Day-Date 36 in rose gold, alligator leather remains the most refined choice: its natural grain creates formal elegance and the lightweight skin ensures comfort during extended wear. Shell cordovan develops a patina over time that dialogues beautifully with rose gold. For those preferring vegetable tanning, naturally tanned calf develops magnificently and achieves golden hues.

The strap is changed by gently removing the spring bars (using a pin bar tool or spring bar tool) connecting the strap to the case lugs. Extract the first pin, slide off the old strap, and insert the new one, ensuring the spring bars are repositioned firmly until they click into place. If unfamiliar with the process, have a professional handle the swap.

All straps with a 20mm lug width are compatible with the 128345RBR-0075. Recommended materials include: alligator, shell cordovan, vegetable-tanned calf, and sports rubber. Online and at Casati Milano, an extensive selection of artisanal 20mm straps is available.

A quality leather strap (alligator, cordovan, vegetable-tanned calf) typically lasts 3-5 years with moderate daily wear. Longevity depends on exposure to moisture, perspiration, and UV rays. A vegetable-tanned strap can last 5-7 years and develops a desirable patina. With proper care and storage in dry conditions, longevity increases significantly.
