Strap for Datejust 36 Stainless Steel Diamond / Oyster / Black Arabic

The lug width of the Rolex Datejust 36 116244-0042 is 20 millimetres. This is the internal width of the opening where the strap is inserted into the watch case. You can verify this measurement by using a digital calliper or consulting the official Rolex documentation. It is essential to select a strap with the correct lug width to ensure proper fit without risk of damage to the case.

The best strap choice depends on your use case and aesthetic preferences. Black alligator remains the aristocratic choice for formal occasions, thanks to its fine and homogeneous grain. Vegetable-tanned leather offers a natural texture and ages beautifully. Shell cordovan represents a sporty yet refined option. All these materials, crafted with a 20mm lug width, pair perfectly with the white gold and stainless steel two-tone finish of your Datejust 36.

The strap on a Rolex Datejust 36 is changed using a specialized spring-bar removal tool. Place the watch on a soft surface, locate the small holes in the lugs, gently insert the tool to compress the spring-bars, and remove the worn strap. Insert the new strap, ensuring the lug width is 20mm, and allow the spring-bars to click back into place. If you are not experienced with this procedure, we recommend seeking professional assistance to avoid damaging your watch.

Yes, it is possible to use a quality aftermarket strap on a Rolex Datejust 36, provided it features a 20mm lug width. However, it is essential to select a strap of superior quality, crafted from noble materials such as alligator, vegetable-tanned calf leather, or shell cordovan. Low-cost synthetic or inferior leather straps can compromise the aesthetic of your watch and damage the case. Casati Milano specialises in custom 20mm straps in artisanal leather, guaranteeing superior quality and bespoke craftsmanship tailored to your wrist.

The longevity of a leather strap depends on material quality, intensity of use, and maintenance. A high-quality alligator or calf leather strap, worn daily, typically lasts 3–5 years before showing significant signs of wear. With regular maintenance (dusting, protection from humidity), durability can be extended. Shell cordovan is renowned for extraordinary longevity, lasting 7–10 years or longer. Straps crafted by Casati Milano include an 18-month warranty against manufacturing defects and can be refreshed through relining or replacement services.
