Datejust 36 116233-0168— lug 20mm

The Rolex Datejust 36 reference 116233-0168 has a lug width of 20mm. This measurement is taken with a digital calliper positioned between the inner walls of the lugs at the point where the strap attaches to the case. 20mm is the most widespread standard in fine watchmaking, ensuring maximum availability of compatible straps, both OEM and aftermarket.

For the two-tone yellow gold and steel version of the Datejust 36, a vegetable-tanned alligator strap with a glossy finish is the most coherent choice given the watch's formal character. The rounded scale grain echoes the fluted bezel visually. Alternatively, glossy box calf leather offers restrained elegance, while shell cordovan develops a unique patina over time. A deployant clasp is preferable to a tang buckle for even load distribution and extended strap life.

The strap on the Rolex Datejust 36 is secured to the lugs via standard 20mm spring bars. To remove it, use a dedicated spring bar tool or a flat-head screwdriver with a scratch-protection tip. Compress the spring bar inside the lug, extract the strap, and reverse the process to fit the new one. It is advisable to have this done by a watchmaker or specialist atelier to avoid scratching the gold lug surfaces.

Yes. The Rolex Datejust 36 uses standard 20mm spring bars, making it fully compatible with any aftermarket strap produced to the correct tolerances. Milanostraps.it offers a curated selection of handcrafted 20mm straps made specifically for this model, with materials and finishes chosen to complement the two-tone case. The Casati Milano atelier also produces bespoke straps with direct leather selection.

The lifespan of a leather strap depends on the material, care and frequency of use. A quality vegetable-tanned alligator strap, worn daily and kept away from excessive perspiration and water, typically lasts between three and five years while retaining good structural integrity. Shell cordovan has a comparable lifespan but develops a patina that makes it aesthetically more interesting over time. Using a deployant clasp reduces mechanical wear at the lugs and the closure point, significantly extending the strap's life.
