Datejust 36 126203-0037— lug 20mm

The lug width of the Rolex Datejust 36 ref. 126203-0037 is 20 mm. This measurement is standardised across the entire Datejust 36 family. The straight lug profile requires straps with straight ends to ensure a precise fit with no lateral play.

For the two-tone Datejust 36 in yellow gold and Oystersteel, the most coherent choices are vegetable-tanned alligator in cognac or midnight blue, shell cordovan for its dense and noble surface, and smooth calfskin for a more understated pairing. A deployant clasp in steel or yellow gold completes the combination whilst respecting the original aesthetic.

To replace the strap on the Datejust 36, use a double-ended springbar tool to release the spring bars from the 20 mm lugs. Work on a soft surface to protect the Oystersteel case and yellow gold bezel. Casati Milano also offers an in-atelier fitting service by appointment.

Yes, the aftermarket offers a wide selection of 20 mm straps compatible with the Datejust 36 ref. 126203-0037. The handcrafted straps available on milanostraps.it are made with straight ends precisely calibrated for Rolex lugs, available in alligator, calfskin, shell cordovan and rubber, with various buckle and deployant clasp options.

The lifespan of a leather strap depends on the material and frequency of use. A quality vegetable-tanned alligator strap, with minimal maintenance and rotated with other straps, can last between three and five years whilst developing an elegant patina. Cordovan and calfskin offer comparable longevity. Casati Milano straps carry an 18-month warranty against manufacturing defects.
