Strap for Datejust 36 Stainless Steel - Domed / Green / Jubilee

The lug width of the Rolex Datejust 36 reference 126200-0023 is 20 mm. This technical specification defines the distance between the pins connecting the strap to the case and determines the compatibility of any aftermarket strap. Measuring the lug width correctly is essential before purchasing a replacement strap—an incorrect measurement results in incompatible strap purchases.

The best material depends on usage and aesthetic preference. Alligator offers natural symmetric texture that mirrors the cylindrical case geometry. Vegetable-tanned calf develops a golden patina over time. Shell cordovan provides superior density and natural lustre. Rubber is ideal for wet environments. A medium brown calf or alligator strap remains the classic choice that does not age poorly.

Strap replacement requires a specific tool for pin removal (spring bar removal tool). Position the watch with dial facing downward, locate the lower lug, insert the tool into the small hole beside the pin and push gently to release the pin. Repeat for the upper lug. Insert the new strap and secure the pins. If inexperienced, consult a watchmaker: Casati Milano offers installation service with 18-month warranty against manufacturing defects.

Yes, provided the lug width is exactly 20 mm. Artisanal straps of superior quality in alligator, calf or shell cordovan are fully compatible and often offer colour and vegetable-tanning options that Rolex does not produce. The important factor is verifying technical specifications before purchase and ensuring the strap has been manufactured by experienced artisans to guarantee construction precision.

Leather strap durability depends on tanning method, usage and maintenance. A high-quality vegetable-tanned calf strap lasts 3–5 years with daily wear. Shell cordovan, owing to superior density, can last 5–8 years. A well-maintained alligator strap achieves 4–6 years. Maintenance includes avoiding prolonged water immersion, drying the strap quickly after perspiration and occasionally applying a protective balm. Rubber straps last longer, with resistance extending to 7–10 years.
