Strap for Datejust 36 Stainless Steel / Domed / White Roman / Jubilee

The lug width of the Rolex Datejust 36 reference 126200-0007 is 20mm. This measurement is taken with a calliper placed between the lugs at their narrowest point, and is the correct figure to use when purchasing a compatible aftermarket strap.

For the Datejust 36 in Oystersteel, a vegetable-tanned alligator belly strap is the most coherent choice given the watch's formal character. Smooth calfskin suits everyday wear, whilst shell cordovan offers an aristocratic restraint. For sporting or summer use, vulcanised rubber or a heavy nylon NATO are sound functional alternatives.

To replace the strap on the Datejust 36, use a proper springbar tool to remove the spring bars securing the strap to the lugs. Work on a soft cushion to protect the Oystersteel case from scratches. If in doubt, entrust the operation to a watchmaker or visit the Casati Milano atelier.

Yes, the aftermarket offers a wide selection of 20mm straps compatible with the Rolex Datejust 36 126200-0007. Milano Straps handcrafted straps are made with ends tailored to the geometry of Oyster lugs.

The lifespan of a leather strap depends on the quality of the hide, frequency of wear, and daily care. A high-quality alligator or shell cordovan strap, regularly treated with natural waxes and stored away from moisture and direct sunlight, can last between three and seven years with regular use. Using a deployant clasp significantly reduces stress on the leather during fastening, thereby extending the strap's useful life.
