Strap for Datejust 36 Rolesor Yellow Diamond / Jubilee / White Diamond

The lug width of the Rolex Datejust 36 116243-0021 is 20 mm. This measurement represents the distance between the two rivets of the case lug and determines the strap compatibility. Any aftermarket strap must be exactly 20 mm wide at the lug attachment point to fit correctly on the two-tone gold-steel case.

Black semi-gloss calf leather with deployante clasp is the most versatile and classic pairing, as it mirrors the date window and contrasts elegantly with the gold lug. Hermès alligator in taupe brown emphasises the bicolour case. For daily wear, vegetable-tanned calf in honey develops a golden patina over time that optically synchronises with the case gold. The choice depends on usage context and personal preference for static or evolving material aesthetics.

Strap replacement requires two small precision screwdrivers to extract the lug pins. Position the watch on a soft cushion or anti-scratch surface. Open the case with the screwdriver perpendicular to the lug, pushing gently inward to remove the pin. Once the pin is removed, the strap detaches automatically. Repeat on the opposite lug. For reassembly, align the new strap with the lug holes and reinforce the pins maintaining forward pressure. Professional execution is recommended to prevent case scratching.

Yes, compatible aftermarket straps are suitable provided the lug width is exactly 20 mm. MilanoStraps manufactures bespoke leather, alligator and shell cordovan straps specifically engineered for this lug width. Casati Milano straps employ artisanal methodologies and include an 18-month warranty against manufacturing defects. The case's bicolour nature permits broad chromatic versatility: alligator, vegetable-tanned calf, and even woven silk integrate seamlessly without aesthetic compromise.

Leather strap longevity depends on material type and frequency of wear. Vegetable-tanned calf of artisanal quality, worn daily and subjected to regular maintenance (damp cloth cleaning, hydration with neutral creams), lasts between 5 and 8 years before replacement becomes necessary. Hermès alligator, being more scratch-resistant, may endure up to 10 years. Shell cordovan readily achieves 12 years. Wear is both aesthetic and structural: deterioration of the anchor bar, material thinning, elasticity loss. Regular maintenance significantly extends useful life. MilanoStraps offers restoration services for worn straps.
