Frequently asked questions

What is the lug width of the Rolex Datejust 36 116231-0066?

The Rolex Datejust 36 116231-0066 features a lug width (ansa width) of 20mm. This measurement represents the distance between the two metal lugs on the case and determines compatibility with aftermarket straps. It is essential to verify this dimension when purchasing a replacement strap, as an incorrect measurement compromises both aesthetic and functional mounting integrity.

What is the best strap for the Rolex Datejust 36 116231-0066 in two-tone?

For a Datejust 36 in rose gold and stainless steel configuration, recommended materials include: alligator in cognac or dark brown tones, shell cordovan in aged red-chestnut, vegetable-tanned calf leather in natural finish, or technical rubber (FKM) in black or grey for summer wear. Avoid synthetic materials and polished leather, which do not align with the formal severity of the watch. A deployante clasp is preferable to a simple pin buckle for optimal comfort and fit.

How do you change the strap on a Rolex Datejust 36?

Strap replacement requires a specialised tool (springbar tool) to compress the internal spring of the lug and extract the pin. Never use improvised tools, as these risk scratching the case. If you lack experience, it is advisable to entrust the operation to a professional watchmaker or to Casati Milano, our appointment-based bespoke atelier, which ensures correct handling and installation.

Which aftermarket straps are compatible with the Rolex Datejust 36 116231-0066?

All 20mm straps are compatible with the Datejust 36 116231-0066, provided they respect the certified lug width and exhibit construction quality standards appropriate to the watch. We recommend full-grain leather straps (alligator, cordovan, calf), featuring contrasting stitching and metal hardware in stainless steel or gold. At milanostraps.it, you can select from numerous artisanal options specifically engineered for this lug width.

What is the average lifespan of a leather strap for the Datejust 36?

A high-quality leather strap (alligator, cordovan, calf) typically lasts 4 to 6 years with daily wear, owing to the density and resistance of the material. Longevity depends on frequency of use, climatic conditions, and maintenance practices. Prolonged exposure to humidity, excessive heat, and perspiration accelerate ageing. A well-maintained strap, occasionally treated with specialist creams, can exceed 7 years. Bespoke straps from Casati Milano are covered by an 18-month warranty against manufacturing defects.
