Strap for Datejust 36 Stainless Steel Domed / Oyster / Black

The lug width of the Rolex Datejust 36 ref. 116200-0059 is 20mm. This measurement refers to the internal opening between the lugs of the Oyster case in Oystersteel. For a correct fitment, a strap with curved ends is required to match the specific lug geometry of the Datejust 36.

For the Datejust 36 116200-0059 with a silver dial and fluted bezel, the most suitable straps are alligator with symmetrical grain (for a formal register consistent with the bezel), vegetable-tanned calf leather (for a developing artisanal patina over time), or shell cordovan (for grain rigidity and long-term durability). A 20mm curved-end format ensures a precise fit to the Oyster case.

To remove the original strap from the Datejust 36, a fine-tipped springbar tool is required. Insert the tip into the inner groove of the lug to compress the spring bars and release the strap. Care must be taken to avoid scratching the polished lugs. It is advisable to work on a soft surface and, if in doubt, consult a watchmaker or the Casati Milano atelier.

Yes, the aftermarket offers straps compatible with the Datejust 36 in 20mm with curved ends. It is essential to verify that the end piece profile matches the specific curvature of the Rolex Oyster lugs. Milanostraps.it offers a selection of handcrafted 20mm straps made with carefully selected materials, compatible with ref. 116200-0059.

The lifespan of a leather strap depends on the material and daily use. A quality alligator strap, properly tanned and worn on a dry wrist, typically lasts 3–5 years while retaining its structure. Vegetable-tanned calf develops a patina and can last as long if maintained with appropriate products. Shell cordovan, due to its dense fibre structure, is among the most resilient materials and can exceed 5 years of regular use. All Casati Milano straps include an 18-month warranty against manufacturing defects.
