Frequently asked questions

What is the lug width of the Rolex Datejust 36 126201-0021?

The lug width of the Rolex Datejust 36 126201-0021 is 20 millimetres. This dimension is standard for modern generation 36mm Datejust models and is essential for selecting a compatible strap. The measurement must be taken with precision between the attachment holes using a digital calliper to ensure accuracy.

Which strap is recommended for the Datejust 36 126201-0021?

For the Datejust 36 126201-0021, straps in alligator, European calf leather, or shell cordovan are recommended, chosen according to personal style. Alligator enhances the dial's mother-of-pearl with its granular texture. Calf offers sober elegance and ages beautifully. Shell cordovan guarantees legendary durability and a brown tone that harmonises with rose gold. All must have a 20mm lug width and preferably a safety deployante clasp.

How do you change the strap on the Rolex Datejust 36 126201-0021?

Strap replacement requires a specific tool (spring bar tool) to compress the lateral attachment pins. Position the tool in the designated slots of the spring and push inward to release the pin from its seat. Repeat for both sides. Installation of the new strap follows the reverse procedure. It is advisable to consult a professional watchmaker if you are inexperienced, to avoid scratches or damage to the case.

Are aftermarket straps compatible with the Datejust 36 126201-0021?

Yes, any strap with a 20mm lug width is compatible with the Datejust 36 126201-0021. Artisanal straps of superior quality, such as those produced by Casati Milano, offer aesthetic and durability advantages over series straps. It is important to choose premium leathers and certified artisanal construction to ensure longevity and comfort.

How long does a leather strap last on the Rolex Datejust 36 126201-0021?

Durability depends on frequency of use, material, and maintenance. An alligator or shell cordovan strap, with regular care, lasts an average of 3-5 years of daily wear. European calf has similar longevity if protected from excessive moisture. The patina that develops over time is a desirable characteristic that confers uniqueness. Casati Milano guarantees 18 months on manufacturing defects, with possibility of restoration and replacement of normal wear.
