Datejust 36 126233-0038— lug 20mm

The lug width is 20 millimetres. This is the standard specification for all Datejust 36mm watches produced from 2020 onwards. To verify a strap's compatibility, measure the distance between the two lugs that protrude from the case: it must be exactly 20mm. A 18mm or 22mm strap will not be compatible and will leave visible, unsightly gaps.

The choice of strap depends on usage and aesthetic preference. Alligator is the maximalist solution, with natural texture and the ability to develop a rich patina over time. Vegetable-tanned calf leather offers suppleness and longevity, ideal for formal contexts. Technical rubber is perfect for daily wear and moisture-resistant. For the two-tone yellow gold and steel case, we recommend straps in warm tones (havana, cognac) or formal colours (black, slate grey).

Strap replacement requires a specialized tool (spring bar tool) to remove the elastic pins from the case lugs. Position your Rolex on a stable surface, insert the tool into the slot beneath the first pin, apply gentle outward pressure until the pin releases from the lug holes, and remove the strap. Reverse the procedure to install the new strap. If you are inexperienced, entrust the job to a qualified watchmaker to avoid damage to the case.

Yes, the Datejust 36 accepts any quality strap with a 20mm lug width. Bespoke straps crafted by specialised ateliers (such as Casati Milano) guarantee superior fit and durability compared to mass-produced alternatives. Always verify that the width is exactly 20mm to avoid incompatibility.

A high-quality leather strap (alligator, vegetable-tanned calf) lasts an average of 3 to 5 years with daily wear, provided it receives regular maintenance. Longevity depends on exposure to moisture, perspiration and mechanical wear. Artisanal straps crafted by specialised ateliers tend to last longer thanks to material quality and sartorial construction. A technical rubber strap has a similar lifespan but resists environmental stress and moisture better.
