Strap for Datejust 36 Stainless Steel / Fluted / Slate - Roman / Oyster

The Rolex Datejust 36 ref. 126234-0046 has a lug width of 20mm. This measurement refers to the internal distance between the case lugs and is the key specification for selecting a compatible strap. The lugs require curved-end strap tips to fit correctly against the 36mm Oyster case profile.

For the two-tone white gold and steel Datejust 36, a lustrous hornback alligator strap represents the canonical pairing in fine watchmaking. Vegetable-tanned calf leather is ideal for those seeking a personal patina over time, whilst shell cordovan offers a dense, compact texture with near-specular reflections. A deployant clasp in steel or white gold completes any choice with security and ease of use.

Replacing the strap on the Datejust 36 requires a fine-tipped springbar tool with a 0.7–0.8mm point. The springbars are compressed by applying gentle leverage into the lug holes. Work on a soft surface to avoid scratching the case. If you lack experience, it is advisable to entrust the operation to a watchmaker or the Casati Milano atelier.

Yes. The aftermarket offers straps compatible with a 20mm lug width and curved ends specific to the Oyster case. Milanostraps.it offers a selection of handcrafted 20mm straps in leather, rubber and fabric compatible with the Datejust 36. Casati Milano also produces fully bespoke straps with personal leather selection in the Milanese atelier.

Longevity depends on the leather type and frequency of wear. A quality alligator strap, properly maintained, retains its structural integrity and appearance for 3–5 years of regular use. Vegetable-tanned calf develops patina but may show wear sooner. Shell cordovan, with its dense fibre structure, is among the most durable options. Casati Milano provides an 18-month guarantee against manufacturing defects.
