Frequently asked questions

What is the lug width of the Rolex Datejust 36 126233-0023?

The Rolex Datejust 36 in the 126233-0023 variant features a lug width of 20 millimetres. This is the standard width for the 36-sized Datejust family, measured as the internal distance between the horizontal lugs on the case. This specification is essential to ensure compatibility with any aftermarket strap.

Which strap is best suited for the Rolex Datejust 36 126233-0023?

For the 126233-0023 with mother-of-pearl dial and Rolesor case (steel and yellow gold), alligator is the ideal pairing. The regular texture of the scutes and the patina that develops over time create harmony with the case's noble materials. Valid alternatives include vegetable-tanned calf in dark tones (chocolate brown or black) for aesthetic contrast, or natural rubber for casual daily wear.

How do you change the strap on a Rolex Datejust 36 126233-0023?

Strap replacement requires a specialised tool called a 'removal tool' to extract the pins holding the strap to the case lugs. Inserting the tool gently into the narrow space between lug and pin, one presses until the pin is freed from its internal spring. The old strap then comes away easily, and the new one is attached by reversing the procedure. Extreme care is advised to avoid scratching the yellow gold case.

Is an aftermarket strap compatible with the Datejust 36 126233-0023?

Yes, any strap with a 20-millimetre lug width is compatible with the 126233-0023. Artisanal straps crafted by ateliers such as Casati Milano are constructed to Rolex Datejust 36 specifications and guarantee precise fit to the original case lugs. Compatibility is guaranteed by the lug width specification, regardless of the strap manufacturer.

How long does a leather strap last on a Rolex Datejust 36 126233-0023?

The lifespan of a leather strap depends on material and usage patterns. Alligator in vegetable tanning, if subjected to periodic maintenance (light conditioning every 12–18 months), maintains functional integrity for 4–6 years. Vegetable-dyed calf exhibits a slightly shorter lifecycle, from 3 to 5 years depending on exposure to humidity and direct sunlight. Casati Milano provides an 18-month warranty against manufacturing defects, covering the initial settling period of the material.
