Datejust 36 116201-0081— lug 20mm

The Rolex Datejust 36 reference 116201-0081 features a 20-millimetre lug width, which is the precise distance between the two upper lateral lugs of the case. It is essential to verify this measurement before purchasing an aftermarket strap, as an incorrect lug width could damage the lugs or appear aesthetically incongruous.

For the 116201-0081 model, the ideal strap is Mississippi alligator or Nile crocodile, whose regular finish and characteristic grain enhance the nobility of the 18-carat rose gold. Excellent alternatives include shell cordovan for those seeking a natural patina over time, black polished calf for formal occasions, and vegetable-tanned leather for a vintage-contemporary aesthetic. The choice depends on intended use and personal colour preferences.

Strap replacement requires a spring bar tool, a specialised instrument with two flat ends allowing compression of the elastic pin of the old strap. Position the tool under the pin from one side, press gently until the pin springs free from its seat, then extract the old strap. Insert the new strap by aligning its pins with the case slots, pressing until fully seated. Avoid abrupt movements that could scratch the case. If uncertain, consult an authorised service centre.

Yes. Artisanal leather straps barrel-dyed and handmade with a 20mm lug width are fully compatible with the Datejust 36 and, when crafted by experienced artisans, deliver quality exceeding many catalogue products. Milanostraps.it offers a collection of 20mm-width straps constructed from alligator, shell cordovan and vegetable-tanned leather, each engineered for dimensional precision and longevity. For bespoke personalised service, the Casati Milano atelier allows selection of leather directly, monitoring of craftsmanship, and delivery with an 18-month production defect warranty.

Longevity varies according to material, construction quality and usage conditions. An alligator or shell cordovan strap, if crafted using artisanal techniques and subject to regular maintenance, can endure 5–10 years of daily use. Vegetable-tanned leather typically develops characteristic patina and may last 3–7 years before requiring replacement due to wear. Prolonged exposure to humidity, perspiration and ultraviolet light significantly reduces lifespan; to preserve the strap, rotate usage amongst several straps, dry the strap after humidity exposure, and periodically apply specialist leather balm.
