Strap for Datejust 36 Stainless Steel / Diamond / Blue Jubilee / Oyster

The lug width of the Rolex Datejust 36 126284RBR-0004 is precisely 20 millimetres. This measurement is taken from the inner shoulder of one lug to the inner shoulder of the opposite lug. Strict adherence to 20 mm is essential to prevent gaps or misalignment of the strap on the case.

Alligator leather in vegetable tanning represents the supreme choice for this two-tone white gold and steel model. The fine grain and natural patina enhance the champagne dial. Valid alternatives include shell cordovan with burnished patina or gummed calf leather with concealed deployante clasp for those prioritising quick changes and practicality.

Strap replacement on the Datejust 36 126284RBR-0004 is accomplished by removing the two spring bars connecting the strap to the case lugs. Use a dedicated spring bar tool to gently push the pin and release it from its seat. Install the new 20 mm artisanal strap by threading the spring bars into it, then reinsert them into the lugs. Care must be taken to avoid scratching the white gold case.

No, it is imperative that the strap is specifically dimensioned at 20 mm. Generic or incorrectly sized straps (19 or 21 mm) will cause visual misalignment and mechanical stress on the lugs. Always opt for quality straps manufactured to this specific lug width, preferably artisanal pieces like those from Casati Milano.

A quality leather strap, such as those in artisanal alligator or shell cordovan, typically lasts 3–5 years with daily wear, depending on frequency of use and environmental conditions. Vegetable tanned leather naturally develops patina without compromising function. Casati Milano guarantees 18 months against manufacturing defects. Longevity depends on care: avoid prolonged exposure to salt water and excessive humidity.
