Frequently asked questions

What is the lug width of the Rolex Datejust 36 126283RBR-0004?

The Rolex Datejust 36 126283RBR-0004 features integrated lugs with a width of 20 millimetres. This measurement represents the distance between the two spring bars onto which the strap is fitted and determines compatibility with any aftermarket strap. Accurate measurement of this distance is essential to avoid straps that are too tight or excessively wide, which could cause fitting issues and potential damage to the case.

Which strap material is most suitable for the two-tone Datejust 36 in gold and steel?

For the two-tone Datejust 36 126283RBR-0004, alligator leather represents the most traditional and refined choice, particularly in dark brown or black tones. Vegetable-tanned calf leather offers an elegant and sustainable alternative, ideal for daily versatility. For those seeking maximum quality and longevity, Japanese shell cordovan delivers extraordinary colour depth and ageing characteristics. Rubber or silicone straps also remain valid for sports contexts without compromising the two-tone elegance.

How do you correctly replace the strap on a Rolex Datejust 36?

Strap replacement requires specific tools: a spring bar removal tool or a fine, delicate implement to compress the elastic pins. Position the watch securely, gently compress one spring bar to release pressure on the pin, then extract the old strap. Insert the new strap by aligning one lug first, then compress the opposite spring bar to engage the second pin. If you lack the tools or experience, it is advisable to consult a professional watchmaker to prevent damage to the case.

Which aftermarket straps are compatible with the 20mm lug width of the Datejust 36?

Any aftermarket strap with a 20-millimetre lug width is compatible with the Datejust 36 126283RBR-0004. milanostraps.it offers an extensive selection of 20mm straps in various materials: alligator, calf, shell cordovan, NATO fabric and rubber. It is advisable to opt for a deployante clasp to improve comfort and reduce wear, particularly important on luxury watches such as Rolex.

How long does a leather strap last on a watch worn daily?

The lifespan of a leather strap depends on multiple factors: frequency of use, exposure to sweat, humidity and leather type. High-quality alligator or calf leather, worn daily with ordinary care, typically lasts 2–4 years before replacement becomes necessary due to natural wear. Shell cordovan tends to last longer due to its inherent structure. Proper maintenance—avoiding prolonged water immersion, drying quickly after perspiration, applying leather-specific conditioners—significantly extends longevity. Straps handcrafted by Casati Milano benefit from an 18-month warranty against manufacturing defects.
