Day-Date 36 118208-0353— lug 20mm

The lug width (strap width) of the Rolex Day-Date 36 118208-0353 is 20 millimetres. This technical specification is determined by the width of the yellow gold case and the geometry of the screwed lugs. It is essential to verify this measurement before selecting an aftermarket strap to ensure perfect compatibility and correct aesthetic proportions.

For the Day-Date 36 reference 118208-0353 in yellow gold, an alligator strap in dark brown (Mahogany or Tobacco) represents the classic choice, as it emphasises the warm tone of the metal. Alternatively, vegetable-tanned calf leather or shell cordovan offers natural patina that develops over time. For a more informal option, a canvas NATO strap in sand tone maintains formal dignity while offering a relaxed aesthetic.

The lugs of the Day-Date 36 118208-0353 are screw-attached. To change the strap, you must unscrew the lug screws using an appropriate micrometring screwdriver, remove the previous strap, and position the new one, ensuring the lug width is 20 millimetres. It is advisable to have this operation performed by a specialist watchmaker to avoid damage to the screws or case.

Yes, you can fit quality aftermarket straps, provided the lug width is 20 millimetres and the construction thickness does not exceed 5 mm to maintain aesthetic proportion. Casati Milano produces artisanal straps in alligator, calf and rubber specifically compatible with this reference, with an 18-month warranty.

The lifespan of a natural leather strap depends on frequency of use, sun exposure and humidity. Under normal conditions, a quality alligator or calf strap lasts 3–5 years before requiring replacement. Vegetable-tanned leather ages naturally, developing patina, whilst surface-dyed leathers may darken. Casati Milano offers an 18-month warranty against manufacturing defects.
