Strap for Rolex Datejust 36 116231

The Rolex Datejust 36 ref. 116231 features a lug width of 20 millimetres. This dimension is specific to the model and is determined by the distance between the case lugs. A compatible strap must precisely respect this 20mm tolerance to ensure comfort and safety. An incorrect measurement results in purchasing an unsuitable strap.

For the 116231 Rolesor Everose two-tone, alligator is the most sophisticated choice, thanks to its uniform texture and patina that improves over time. Calf leather with vegetable tanning is versatile and resists creasing well. For those seeking contemporary styling, shell cordovan offers quasi-metallic properties and intrinsic lustre. Technical rubber is the solution for sporty contexts, whilst a NATO with leather base combines versatility and elegance.

Strap changing is accomplished using a specialised tool (spring bar tool) that allows the lateral pins of the case to spring in and retract. Rolex recommends avoiding improvised tools and having the operation performed by a professional watchmaker to prevent case damage. Casati Milano provides a dedicated service for installation of their straps, ensuring precision and traceability of the work.

Yes, an aftermarket strap is compatible provided the lug width is exactly 20mm. Rolex does not prohibit the use of third-party straps; indeed it expressly authorises them. The quality of the strap is decisive: noble materials (alligator, shell cordovan, vegetable-tanned calf) ensure durability and an ageing patina that narrates worn time.

The lifespan of a leather strap depends on intensity of use, climatic conditions and care applied. A high-quality alligator strap can last 5–7 years of daily wear before requiring replacement. Calf leather with vegetable tanning offers slightly superior resilience due to more robust fibre structure. Prolonged exposure to moisture and direct sunlight accelerates ageing; storage in a dry, cool environment with periodic application of specific balms significantly extends the strap's operational life.
