Strap for Datejust 36 Stainless Steel - Diamond / Green - Palm - Diamond / Jubilee

The lug width (distance between lugs) of the Rolex Datejust 36 126284RBR-0047 measures 20 millimetres. This dimension is the fixed internal distance between the two lugs of the case. It is a manufacturing standard for this reference that allows compatibility with aftermarket straps fitted with 20mm spring bars.

For the Datejust 36 in white gold and stainless steel, alligator leather with vegetable tanning is the most harmonious choice: the naturally linear grain does not compete visually with white gold, and the patina develops chromatic unity over time. Shell cordovan offers superior tactile density with subtle light reflections. Vegetable-tanned calfskin provides chromatic versatility—cognac brown for formality, greige for contemporary styling.

This requires a specific tool: a spring bar tool or pin punch. Place the watch on a stable surface with the lug side facing upward. Gently insert the pin punch into the spring bar hole and push the bar inward to release the spring mechanism. Extract the spring bar from the lug and install the new strap by reversing the procedure. If unfamiliar with this operation, professional guidance from a qualified watchmaker is advisable to prevent case scratching.

Yes. The 20mm lug width is a robust industry standard that grants access to an extensive ecosystem of artisan straps. Aftermarket 20mm straps are 100% mechanically compatible with the spring bar attachment system. Specialised craft producers—such as custom straps from Casati Milano—can match or exceed official Rolex straps in aesthetic finish and longevity.

An alligator strap with vegetable tanning, subjected to standard care (moderate humidity, avoiding prolonged saltwater exposure), has an estimated lifespan of 3–4 years under daily wear. Variables such as perspiration, temperature fluctuation and frequency of use accelerate ageing. Casati Milano provides an 18-month warranty against manufacturing defects. A strap is not a permanent component like the case: periodic replacement should be considered routine maintenance of the watch.
