Strap for Datejust 36 Rolesor Everose Fluted / Oyster / MOP

The lug width of the Rolex Datejust 36 116231-0079 is 20 mm. This measurement corresponds to the physical distance between the case lugs (the small metal pins that anchor the strap). Always verify this measurement before purchasing an aftermarket strap: an 18 mm strap will not sit properly, whilst a 22 mm strap will be physically incompatible.

For a Datejust 36 116231-0079 with mother of pearl dial, the finest choice is alligator in Nile vertical grain (cognac or dark brown) or calf leather in vegetable tanning with natural finish. Both materials complement the luminescence of the MOP without overwhelming the delicate two-tone case design. Alligator offers refined texture and elegant chromatic contrast, whilst vegetable-tanned calf develops natural patina over time, creating a biographical relationship with the watch.

To change the strap, acquire a spring bar tool (a small lever-shaped instrument). Position the tool beneath the case lug and gently lift until the internal coil springs release. Remove the old strap and insert the new one by aligning the holes with the case pins, then reseat the pins until they click into position. If uncertain, entrust the task to a specialist watchmaker.

Yes, it is possible to use a quality artisanal aftermarket strap on the Datejust 36 116231-0079, provided the lug width is precisely 20 mm and the strap is crafted from noble materials with precise workmanship. Straps in alligator, shell cordovan, vegetable-tanned calf, or vulcanised rubber are all technically and aesthetically valid choices. Always select specialised suppliers who guarantee mechanical compatibility.

A noble leather strap (alligator, calf, cordovan) has an average lifespan of 3–5 years depending on usage and care. If worn daily and subjected to continuous exposure to moisture, perspiration and sunlight, the leather will lose elasticity sooner. Vegetable tanning develops a patina that nobly ages the material, whilst chrome-tanned leather tends to chip. Regular maintenance (cleaning, conditioning, rest) significantly extends strap life.
