Strap for Datejust 36 Stainless Steel Diamond/ Oyster / Bronze Wave

The Rolex Datejust 36 reference 116244-0037 features a 20-millimetre lug width. This measurement represents the distance between the lugs (attachment points) on the case. It is essential to verify that your strap is manufactured specifically for this tolerance, as it is not compatible with 18mm or 19mm straps. To check the measurement on your watch, remove the current strap and use a calliper to measure the distance between the centres of the two lugs.

For a two-tone Datejust 36 with steel and white gold, we recommend honey-toned alligator with vegetable tanning, which develops natural patina over time and enhances the two-tone case without competing with it. Shell cordovan offers a compact texture and elevated aesthetic solidity. Tuscan calf represents a contemporary alternative that ages beautifully. For informal wear, a NATO strap in cotton maintains correct proportions. Rubber straps provide practicality in aquatic environments. The choice depends on your intended use and frequency of strap rotation.

Changing the strap on a Datejust 36 requires specific tools: a spring bar removal tool and a magnifying lens. Locate the small holes on the case next to the lugs, carefully insert the tool to compress the inner lug, then extract the old strap. Position the new strap (ensuring it has a 20mm lug width) and press until you feel the lug click into the case grooves. If you are inexperienced, we recommend having a qualified watchmaker or specialised atelier such as Casati Milano perform the operation.

Yes, it is possible to use quality aftermarket straps on a Rolex Datejust 36 116244-0037, provided they are manufactured for 20mm lug width and made with noble materials (alligator, shell cordovan, premium calf). Choosing an artisanal strap also guarantees superior durability compared to budget straps and allows customisations not available in original Rolex straps. Many collectors prefer to rotate different straps on the same watch to vary daily aesthetics without compromising quality.

The lifespan of a leather strap depends on the material and usage patterns. A quality alligator or shell cordovan strap, with vegetable tanning and daily wear on a wrist with moderate humidity, typically lasts between 4 and 8 years. Artisan Tuscan calf resists 3-5 years with consistent care. Natural wear is accelerated by very humid climates, prolonged direct sun exposure, and salty perspiration. A Casati Milano strap includes an 18-month manufacturing defect warranty and recommended maintenance: periodic cleaning, treatment with natural balm every 6-12 months, and careful drying after water contact.
