Strap for Datejust 36 Rolesor Yellow Domed / Oyster / Silver Floral

The lug width of the Rolex Datejust 36 116203-0146 is precisely 20 millimetres. This measurement represents the internal distance between the watch lug shoulders where the strap inserts. To verify it yourself, use a digital calliper positioned between the spring bar pins. Our artisanal straps are manufactured to a tolerance of ±0.1 mm, ensuring a perfect fit.

For the Datejust 36 116203-0146, we recommend three primary options: alligator with vegetable tanning (tobacco brown or black), calf leather with accelerated ageing (cognac or burgundy), or FKM rubber for summer wear. Alligator emphasises the gold component of the case, whilst calf develops a patina that enhances the two-tone's luminosity over time. Rubber offers a contemporary contrast, ideal for seasonal rotations.

The procedure requires a dedicated tool called a spring bar remover (essentially a small forked screwdriver). Insert the tool into the lateral grooves of the spring bar, applying gentle inward pressure until the bar retracts. Once compressed, extract the horizontal pin and remove the existing strap. Align the new strap's holes with the lugs and reinsert the spring bar, ensuring it seats completely before wearing the watch.

Yes, provided it respects the 20 mm lug width specification. Casati Milano's artisanal straps are manufactured to stringent tolerances (±0.1 mm) specifically for Rolex compatibility. Avoid generic straps that may cause slippage or lug damage. We always recommend verifying technical specifications before purchase and contacting us for consultation if uncertain.

A premium leather strap, vegetable-tanned with artisanal construction, typically lasts 4–6 years with moderate daily wear. Longevity depends on frequency of use, sun exposure, ambient humidity, and maintenance care. Alligator straps generally outlast standard calf leather. We recommend avoiding prolonged water contact and periodically conditioning the leather with specialist balms to preserve flexibility and colour. Casati Milano's guarantee covers 18 months against manufacturing defects.
