Strap for Datejust 31 Rolesor Yellow Fluted / Oyster/ Black MOP

The lug width (distance between the lugs) of the Rolex Datejust 31 178273-0081 is 16 millimetres. This measurement is taken from inside to inside of the two pins that connect the case to the strap. This is a well-established size in the aftermarket watch strap industry, allowing compatibility with numerous high-quality artisanal and industrial straps.

For the Datejust 31 in Rolesor with mother-of-pearl dial, the finest matches are African alligator for pure elegance, vegetable-tanned leather for everyday versatility, or a silk-synthetic twill NATO for practicality without aesthetic compromise. Black alligator with a gold-plated deployant clasp creates maximum contrast, whilst a cognac-aged tone amplifies the yellow gold of the case.

Changing the strap on the Datejust 31 involves removing the connecting pins (spring bars) using a dedicated tool: a spring bar remover with refined tips. The procedure requires precision to avoid scratching the case: position the tool under the pin, apply gentle pressure and extract the pin from its seat. Then insert the pins into the new strap and reconnect them to the case. If uncertain, professional service is recommended.

Yes, any strap with a 16mm lug width is compatible with the Datejust 31 178273-0081. Aftermarket and artisanal straps offer customisation impossible with original Rolex offerings, allowing you to select materials (alligator, shell cordovan, vegetable-tanned leather) and bespoke finishes. Always verify that the lug width is exactly 16mm and that the pins used are appropriate.

A high-quality artisanal leather strap, made from alligator or vegetable-tanned leather, has an average lifespan of 3–5 years with moderate daily use, provided minimal maintenance is applied: avoid stagnant water, do not expose to excessive heat, occasionally clean with a damp cloth. Vegetable-tanned leather develops a natural patina that improves over time. With greater care and rotation between multiple straps, durability extends considerably.
