Strap for Datejust 36 Rolesor Yellow Diamond / Jubilee / Silver

The lug width of the Rolex Datejust 36 116243-0061 is 20 millimetres. This dimension represents the distance between the case attachment pins and must be matched precisely to ensure the strap sits flush without wobbling or misalignment. You can verify this measurement using a digital calliper, measuring from the centre of one pin to the centre of the opposite attachment pin.

For this yellow gold and stainless steel bicolour, we recommend straps in crocodile alligator (with consistent grain and natural finish) or vegetable-tanned calf leather (which develops patina over time). Alligator amplifies the lustre of yellow gold and catches light like dial details. Pure aniline calf offers colour transparency and understated elegance. Warm browns (cognac, tobacco, mahogany), smoke greys, polished blacks and burgundy are the most harmonious colours with this material configuration.

The Datejust 36 lug attachment pins are controlled by internal springs: use a spring bar tool to compress the spring mechanism, insert the pin into the lower hole at one end, allow the spring to click back into place, then repeat at the opposite end to fully extract the pin. Proceed in reverse to install your new strap. If unfamiliar with the procedure, consult a certified watchmaker to avoid case damage.

Yes, any strap manufactured for 20mm lug width is compatible, regardless of maker. However, quality varies considerably: established brands such as Hirsch, Barenia, Everest and specialised artisans guarantee secure pin retention, stitch integrity and controlled ageing. Avoid universal compromise straps spanning multiple widths—these sacrifice stability and compromise pin behaviour. Casati Milano manufactures 20mm straps calibrated for the Datejust with construction specifications identical to Rolex standards.

A quality leather strap (crocodile alligatore, vegetable-tanned calf, shell cordovan) typically lasts 3–5 years with moderate daily wear, or 5–8 years if rotated with other straps. Longevity depends on exposure to moisture, perspiration, salt spray and UV radiation. Vegetable-tanned leather naturally develops patina and hardens over time, extending useful lifespan. We recommend alternating straps, applying leather conditioner every six months and storing in a dry environment. A deteriorated strap can be restored by a specialist craftsman; Casati Milano offers this restoration service.
