Frequently asked questions

What is the lug width of the Rolex Datejust 36 126201-0044?

The lug width of the Rolex Datejust 36 126201-0044 is 20 millimetres. This measurement is determined by the geometry of the case lugs and represents the distance between the upper and lower attachment points. To verify this correctly, place a ruler on the inner surface of the lug without compressing the metal.

Which strap material is most suitable for the bicolour Datejust 36 126201-0044?

Alligator represents the most versatile choice: its natural texture of regular scales dialogues perfectly with the combination of steel and rose gold. Shell cordovan offers formal elegance with a patina that evolves over time, whilst vegetable-tanned calf guarantees sustainability and tactile softness. FKM rubber is ideal for sporty contexts, whilst NATO straps provide a casual-chic aesthetic.

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

Strap replacement requires a specific tool (spring bar tool). Position the watch on a soft surface, identify the elastic pin (spring bar) that supports the strap, compress it slightly towards the centre of the case and slide the strap out. Insert the new strap ensuring the pin locks fully into the lugs. Avoid excessive pressure to prevent scratching the case.

Is an aftermarket strap compatible with the Datejust 36 126201-0044?

Yes, any strap with a 20mm lug width is compatible with the Datejust 36 126201-0044. High-quality artisanal aftermarket straps (such as those made by Casati Milano) offer aesthetic and material customisation that often exceeds original Rolex proposals, whilst maintaining full mechanical compatibility.

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

The longevity of a leather strap depends on use, material and care. Quality artisanal alligator, with proper maintenance, can last 5-8 years. Vegetable-tanned leather tends to age visibly after 3-5 years. Factors such as humidity, perspiration, sun exposure and frequent washing reduce longevity. Eighteen-month warranties against manufacturing defects are standard in the artisanal sector.
