Strap for Datejust 36 Rolesor Everose Domed / Jubilee / Silver Computer

The lug width (strap width) of the Rolex Datejust 36 reference 116201-0061 is 20 millimetres. This measurement is essential when sourcing compatible replacement straps. It is measured with a digital calliper between the two attachment points (lugs) where the strap connects to the case. For the Datejust 36, a tolerance of ±0.5mm is acceptable; beyond these limits the strap will be either loose or undersized.

For this two-tone reference in rose gold and stainless steel, four primary options are advised: American alligator (distinctive grain pattern and luminous reflectivity); calf leather with vegetable tanning (develops a noble patina over time); shell cordovan (maximum density and longevity); technical rubber or NATO fabric for informal contexts. Cognac-coloured alligator and black calf create the most harmonious visual balance with the bimetallic case.

Changing the strap on a Datejust 36 requires precision. Position the watch on a soft cushion and locate the spring bars (small metal rods) that secure the strap to the lugs. Use a dedicated spring bar removal tool to depress the spring and slide the bar out of the lug hole. Repeat on the opposite side. Insert the new strap by aligning its attachment hole with the spring bar, then press the bar into the opposite lug until you hear a click indicating secure closure.

Yes, provided the strap is manufactured for a 20mm lug width and the internal attachment points are engineered to the same tolerances as the Rolex original. Specialised strap makers such as Casati Milano produce components built to precise specifications, guaranteeing absolute compatibility without excessive play or friction against the case lugs.

Longevity depends on material type, tanning method and intensity of use. High-quality alligator with vegetable tanning lasts 4-6 years under daily wear conditions; shell cordovan may exceed 7-8 years due to superior density. Technical rubber lasts 3-4 years before deterioration. Limiting factors include humidity, perspiration, direct sunlight exposure and cleaning frequency. Casati Milano provides an 18-month warranty against manufacturing defects, independent of natural wear.
