Datejust 36 116234-0078— lug 20mm

The lug width of the Rolex Datejust 36 116234-0078 is 20 millimetres. This is the distance between the pins connecting the strap to the case lugs. For perfect compatibility, your aftermarket strap must respect this measurement with a tolerance below 0.3 millimetres. Inaccurate measurement results in a strap that is either too loose or too rigid.

The best strap depends on your usage. For formal occasions, alligator with fine grain in anthracite, burgundy or cream white tones. For everyday elegance with developing patina, French vegetable-tanned calf leather. For water resistance and durability, Japanese shell cordovan. For contemporary versatility, brushed suede or technical rubber. All these materials harmonise beautifully with the white mother-of-pearl dial and two-tone case.

Strap replacement requires a specialised tool (spring bar extractor) and careful handling to avoid damaging the case. Position your watch on a protected surface, identify the fixing pin on the case lug, apply lateral pressure with the tool until the pin retracts, then remove the old strap. Align the new strap with the lug holes, insert the pin and verify it is fully secured. If inexperienced, consult a certified watchmaker or Casati Milano.

Yes, any strap with a 20mm lug width is compatible. It is essential to choose a high-quality strap crafted from noble materials and artisanal construction, ensuring you do not compromise the aesthetics or value of your watch. Casati Milano straps are crafted from premium leathers (alligator, calf, shell cordovan) with hand-stitching, guaranteeing perfect compatibility and superior durability.

Durability depends on material type, frequency of use and storage conditions. A quality alligator or calf strap lasts approximately 3-5 years with daily wear. Shell cordovan, owing to its density, reaches 5-7 years. Prolonged exposure to moisture, direct heat and UV rays reduces lifespan. Casati Milano straps include an 18-month warranty against manufacturing defects and consultancy support for maintenance and lifespan extension.
