The Heritage

The Datejust 36 represents the evolution of the model introduced by Rolex in 1945, the first self-winding wristwatch with date indication. It is powered by the automatic Caliber 3135 certified as a chronometer and features hour, minute, and second functions. The 36mm case features 20mm lugs and combines stainless steel and gold.

FAQ

What is the lug width of the Rolex Datejust 36 116203-0153?

The lug width of the Rolex Datejust 36 reference 116203-0153 is 20 millimetres. This measurement is taken between the interior edges of the lugs on the watch case. It is essential for ordering a compatible strap. An incorrect measurement results in an unusable strap.

Which strap do you recommend for the two-tone Datejust 36?

For the 116203-0153 two-tone case (yellow gold and steel), we recommend an alligator strap in chocolate brown or cognac tones with a yellow gold deployante clasp. This combination enhances the case contrast whilst maintaining chromatic coherence. Alternatively, vegetable-tanned calf develops a uniform patina and offers seasonal versatility.

How do you change the strap on a Rolex Datejust 36?

Strap replacement requires a dedicated spring bar tool to compress the elastic pins at the ends of the lugs and slide off the old strap. We do not recommend attempting this yourself: an imprecise movement risks scratching the case. Consult a certified watchmaker or our Casati Milano service.

Are aftermarket straps available that are compatible with the 116203-0153?

Yes. All straps with a 20mm lug width are compatible with the Datejust 36 116203-0153. Milanostraps.it offers a selection of alligator, calf, shell cordovan and technical rubber, crafted to luxury watch standards. Compatibility is guaranteed.

How long does a leather strap last on a Rolex Datejust?

A high-quality leather strap (alligator, calf or shell cordovan) typically lasts 3–5 years with daily wear, varying according to tanning method, sun exposure and ambient humidity. Vegetable-tanned leather ages better than chrome-tanned leather. A clasp or stitching revision can extend lifespan by a further 2–3 years.
