Datejust 36 126201-0017— lug 20mm

The lug width of the Rolex Datejust 36 reference 126201-0017 is 20mm. This measurement is critical: the strap must fit perfectly into the lateral lugs of the case without play or excessive pressure. When ordering an aftermarket strap, always verify that it is manufactured at exactly 20mm.

For the 126201-0017 bimetallic version, we recommend alligator in saddlebrown or French calf in natural shades. These materials harmonise with the warmth of Everose without creating chromatic conflict with the steel. Shell cordovan in burgundy is the premium option for those seeking a leather that develops patina over time. For summer wear, a NATO in anthracite grey or navy blue maintains elegance whilst reducing heat absorption.

The Datejust 36 features threaded lugs on both sides of the case, requiring a precision tool (spring bar remover or punch pin) for removal. It is not recommended to proceed independently without experience: the risk of scratching the case or losing the pins is significant. Consult a trusted watchmaker or Casati Milano, which offers strap change service in the atelier.

Yes, any strap manufactured at 20mm is compatible with the 126201-0017. Choosing an artisanal Italian strap from Milano Straps allows you to personalise the watch whilst maintaining high construction quality and production warranty. Casati Milano offers both ready-made online models and bespoke service by appointment.

A high-quality leather strap (alligator, calf, shell cordovan) with traditional tanning lasts 2-3 years with daily wear and proper care. Longevity depends on usage, ambient humidity and frequency of water exposure. Vegetable-tanned leathers develop patina but require periodic conditioning. With a quality deployante and regular conditioning habits, the strap can last considerably longer. Casati Milano provides straps with an 18-month warranty against manufacturing defects.
