Datejust 36 116200-0072— lug 20mm

The lug width of the Rolex Datejust 36 116200-0072 is 20 millimetres. This dimension, measured centre-to-centre between the case lugs, is the construction standard for the compact 36mm diameter. Any aftermarket strap must respect this specification to ensure compatibility and correct proportions. Always verify the measurement before purchase: do not confuse lug width with strap thickness.

The choice depends on usage and aesthetic preference. Alligator is the natural selection for sartorial elegance owing to its natural vein patterns and patina that improves with time. Shell Cordovan offers chromatic stratification and natural grip. Vegetable-tanned leather is ideal for those who appreciate traditional processing without aggressive chemicals. FKM rubber and NATO textile ensure waterproofing and zero maintenance for sporting contexts. Fine-grain calf leather in vegetable tanning balances immediate softness with longevity.

Strap replacement requires specific tools: a spring bar tool (special lever for the lugs). Position the Datejust on a soft surface, insert the tool tip into the small hole between the case and lug, compress the internal spring slightly to extract the pin. Repeat for the second lug. Install the new strap by reversing the process: insert the pin and allow the spring to snap shut. If inexperienced, consult a watchmaker: an error can scratch the case.

Yes, provided they respect the 20mm lug width. Quality aftermarket straps (alligator, shell cordovan, calf with vegetable tanning) offer greater versatility than the original Rolex strap, allowing you to change appearance without compromising authenticity or value. Avoid generic brands: poor-quality leather wears the lug pin and damages the case lugs. Casati Milano guarantees artisanal straps with construction specifications respectful of Rolex geometry.

Longevity depends on material and usage. Quality alligator (vegetable-tanned) resists 5–7 years of daily wear before material noticeably deteriorates. Shell Cordovan, more robust, can reach 8–10 years. Fine-grain calf lasts 3–4 years in intensive use. FKM rubber offers maximum lifespan (10+ years) but develops inevitable opaque patina. Consistent maintenance (cleaning, protective treatments in vegetable tanning) extends useful life. Casati Milano offers 18-month warranty on manufacturing defects.
