Strap for Datejust 36 Rolesor Everose Domed / Jubilee / White Roman

The lug width of the Rolex Datejust 36 116201-0074 is 20 millimetres. This measurement represents the precise distance between the two pins that support the strap on the case. It is essential to verify this specification before acquiring a replacement strap, as an incorrect tolerance would generate lateral play and compromise the aesthetic integrity of the watch.

For the Datejust 36 116201-0074, materials that maintain the formal dignity of the model are recommended: dark brown alligator (which creates continuity with the Everose gold finishes), vegetable-tanned calf (which develops natural patina over time), or shell cordovan in cognac colour (which enhances the reflective properties of the mixed gold-steel case). The choice depends on usage context and personal preference regarding patina development and maintenance.

Changing the strap on the Datejust 36 requires the use of a spring bar tool (a blade-like instrument) to compress the elastic pins that support the strap on the case. Position the tool gently in the lateral grooves of the case, compress the pin to free one end of the strap, then proceed similarly on the other side. To avoid scratches on the case or damage to components, it is advisable to perform the operation on a flat surface, preferably at a specialised atelier such as Casati Milano.

A quality aftermarket strap is perfectly compatible with the Datejust 36 116201-0074, provided it respects the 20-millimetre lug width. It is important to select materials and finishes (alligator, calf, shell cordovan) that maintain aesthetic coherence with the Everose gold and stainless steel case. Casati Milano produces artisanal straps in 20mm specifically designed for this model.

The lifespan of a leather strap depends on the selected material, frequency of use, and environmental conditions. A well-maintained alligator or shell cordovan strap can last 5–8 years of daily wear, whilst vegetable-tanned calf tends to show more visible signs of wear (patina, distressing) within 3–5 years. Casati Milano's 18-month warranty covers manufacturing defects; natural wear and patina are expected phenomena that characterise positive ageing of natural leather.
