Strap for Datejust 36 Stainless Steel Diamond / Jubilee / Pink

The lug width of the Rolex Datejust 36 116244-0050 is 20mm. This measurement refers to the distance between the two spring bar holes where the strap attaches to the case lugs. Accurate measurement is essential to ensure proper fit without play or binding. Even a 1mm error results in incompatibility.

For the bicolour Datejust 36 (white gold and steel), an alligator strap in black or brown is the traditional and most harmonious choice. Alligator offers a fine grain that enhances the watch's luxury appeal, whilst black amplifies the case's bicolour contrast. Vegetable-tanned calf is an elegant alternative that develops patina over time. For sporadic use, vulcanised rubber maintains the dressy aesthetic whilst offering functionality.

Strap change is performed by removing the two spring bars—the transverse pins securing the strap to the lugs. Using a spring bar tool or appropriate instrument, apply pressure from beneath to release the pin from its seat on one side, remove the old strap, and insert the new one by aligning the holes to the bar ends. The procedure requires care to avoid case damage. If inexperienced, consult a professional watchmaker.

Yes, the Datejust 36 116244-0050 is fully compatible with quality aftermarket straps, provided they respect the 20mm lug width. Specialist manufacturers such as Casati Milano produce artisanal 20mm straps in premium materials (alligator, calf, shell cordovan) maintaining high construction standards. Using aftermarket straps does not affect official Rolex warranty coverage.

Leather strap longevity depends on material and usage frequency. Quality alligator, worn daily, maintains integrity for 4-6 years. Vegetable-tanned calf typically lasts 3-5 years before significant wear, though develops an appreciated patina among collectors. Rubber durability mirrors calf (3-5 years). Humidity, perspiration and UV exposure accelerate ageing. Casati Milano provides 18-month warranty on manufacturing defects and can restore or replace worn straps.
