Strap for Datejust 31 Stainless Steel / Yellow Gold / Fluted / Black MOP / Oyster

The Rolex Datejust 31 278273-0023 features a 16-millimetre lug width. This measurement is specific to Datejust 31 models in steel and yellow gold (Rolesor) and ensures constructive compatibility with the 31mm case and fixed lugs of the original bracelet.

For a Datejust 31 278273-0023 with mother-of-pearl dial, an alligator strap in cognac tones or vegetable-tanned leather in warm shades (beige, tobacco) are ideal. Both materials evolve over time, developing patina whilst maintaining aesthetic coherence with the yellow gold bimetallic case.

The strap is replaced by removing the spring bars from the case lugs. Position the watch on a soft support, insert a spring bar tool into the lateral slot and push gently inward whilst extracting the visible end. Align the new strap holes with the lug position and allow the spring bar to reposition automatically.

Yes, provided the lug width is 16 millimetres. High-quality artisanal aftermarket straps are fully compatible with the Datejust 31 and allow aesthetic variation without compromising functionality. We recommend verifying the lug width physically before ordering.

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3–5 years under daily wear. Longevity depends on sun exposure, environmental humidity and cleaning frequency. Vegetable-tanned leather ages visibly, developing patina: this is not a defect, but evidence of authentic wear.
