The Heritage

The Datejust 36 represents the evolution of the model introduced by Rolex in 1945, the first self-winding wristwatch with a date indication. It is equipped with the automatic caliber 3135 with official chronometer certification, featuring hour, minute and second functions. The 36mm case is paired with 20mm lugs.

FAQ

What is the lug width of the Rolex Datejust 36 116243-0024?

The lug width of the Rolex Datejust 36 116243-0024 is 20 millimetres. This measurement represents the horizontal distance between the two lugs of the case, measured from inner edge to inner edge. It is essential not to confuse this dimension with the case diameter (36 mm): correct measurement ensures perfect strap compatibility.

Which strap is most appropriate for the Datejust 36 two-tone?

For the Datejust 36 in two-tone (yellow gold and stainless steel), alligator black with yellow gold deployante clasp represents the most formal choice, whilst vegetable-tanned maroon cordovan offers daily versatility. Shell cordovan is ideal for those seeking leather that develops patina over time. Cotton or linen NATO straps provide lightness during summer months, whilst maintaining the inherent elegance of the model.

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

Changing the strap on a Rolex Datejust 36 requires the use of a spring bar tool, a specialised instrument that allows you to compress the transverse section pins binding the strap to the lugs. This operation should be executed with care to avoid damaging the case: consult an authorised service centre or, for greater convenience, entrust the task to specialised workshops such as Casati Milano, which guarantee maximum precision.

Are there compatible aftermarket straps available for the 116243-0024?

Yes, numerous artisanal manufacturers offer 20 mm straps compatible with the Datejust 36. Quality varies significantly: choosing suppliers specialising in high-end leather work ensures perfect lug fit, refined finishes and longevity. On milanostraps.it you will find a curated selection of compatible straps, crafted according to elevated construction standards.

How long does a leather strap last on a watch like the Datejust 36?

A premium leather strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts between three and eight years, depending on frequency of use, exposure to moisture and sunlight, and maintenance care. A strap used occasionally and stored away from heat sources can remain in excellent condition for a decade. Casati Milano provides an 18-month warranty against manufacturing defects, allowing you to approach periodic replacement with confidence.
