Strap for Datejust 31 Stainless Steel/ Rose Gold / Domed / MOP / Jubilee

The lug width of the Rolex Datejust 31 278241-0026 is 16mm. This measurement is taken between the two internal shoulders of the case, at the point where the strap connects. A 16mm lug width is specific to 31mm Datejust models and accommodates straps with a main body width between 14 and 18mm depending on construction and material.

For the 278241-0026 in Everose gold (Rolex rose gold) and steel with a mother-of-pearl dial, we recommend polished alligator in black or chocolate brown for formal occasions, or vegetable-tanned leather in taupe or grey for sophisticated modernity. Alligator delivers historical formality, whilst vegetable-tanned leather develops authentic patina over time. For sporty contexts, dark grey rubber maintains elegance without compromise.

The strap on a Datejust 31 is changed by removing the lug pins (spring bars) with a dedicated spring bar tool. Insert the thin end of the tool into the small lateral hole beneath the lug to compress the internal spring, then extract the pin. Once freed, the strap disconnects from the case. To install the new strap, position the new pins in the case shoulders and press gently until you hear a click. If unfamiliar, consult a certified Rolex watchmaker.

Yes, any 16mm strap is compatible with the Datejust 31 ref. 278241-0026, provided the lug width is designed for that specific measurement. Quality artisanal aftermarket straps made from alligator, shell cordovan or vegetable-tanned leather offer aesthetics and durability equal to or superior to original Rolex straps, with the advantage of full personalisation and often at a lower cost.

The lifespan of a leather strap depends on usage, material and build quality. A quality artisanal alligator strap can last 5–7 years of daily wear. Vegetable-tanned leather typically lasts 3–5 years. Shell cordovan, thanks to its natural density, can exceed 10 years. Primary wear occurs at the flex point on the wrist and in contact zones with the buckle hardware. Regular maintenance and storage in dry environments significantly extend strap life.
