Datejust 36 116201-0094— lug 20mm

The Rolex Datejust 36 116201-0094 features a lug width of 20mm. This is the distance between the case attachment pins. A compatible strap must be precisely 20mm wide to fit correctly into the lugs without play or friction.

The choice depends on intended use and aesthetic preference. For formal occasions, we recommend vegetable-tanned alligator (pronounced grain) or shell cordovan (natural patina development). For everyday versatility, Hermès calfskin or Tuscan vegetable-tanned leather. For a sport-formal hybrid, structured rubber or Tropic. Pair the material with the Everose-steel two-tone case and select a deployant clasp for secure fit.

Strap replacement requires a spring bar tool. Position the flat end of the tool into the small groove beneath the lug pin, push inward to release the spring pin, and gently extract the pin. Repeat on the opposite lug. Align the new strap with the pins and reinsert the pin from the inside until you hear a click. Verify the fit by gently pulling the strap.

Yes, provided the lug width is exactly 20mm and the strap is made from quality materials (full-grain leather, not composite). Atelier Casati Milano manufactures bespoke straps tailored for this reference, adhering to Haute Couture standards. Lower-quality generic straps are not recommended for timepieces of this caliber, as they risk diminishing both aesthetic appeal and resale value.

A vegetable-tanned leather strap typically lasts 3–5 years with daily wear, depending on wear frequency, environmental conditions (humidity, heat), and leather quality. Shell cordovan ages exceptionally well, developing attractive patina for 5–8 years. Alligator, if properly maintained, exceeds 5 years. Lug pin friction accelerates wear; Casati Milano straps include an 18-month warranty against manufacturing defects.
