Datejust 31 278248-0014— lug 16mm

The lug width of the Rolex Datejust 31 278248-0014 is 16mm. This measurement refers to the internal distance between the case lugs at the point of strap attachment. It is recommended to verify this on your specific piece using a digital calliper for precision.

For the Datejust 31 in yellow gold, an alligator leather strap with a matte finish and deployant clasp is the most coherent choice given the watch's construction quality. Shell cordovan is an excellent alternative, offering a refined surface and distinctive patina over time. For everyday wear, vegetable-tanned calf leather provides an optimal balance between elegance and durability.

The strap on the Datejust 31 is secured via 16mm spring bars. To replace it, use a spring bar tool — either a fork-tip or push-pin type — to compress the spring bars and release the strap from the lugs. It is advisable to work on a soft surface to avoid scratching the yellow gold case.

Yes, high-quality aftermarket straps are available for the Datejust 31 with a 16mm lug width. Milano Straps offers a curated selection of handcrafted straps made specifically for this lug size, available in various materials and finishes, with or without a deployant clasp, suitable for both formal and everyday use.

The lifespan of a leather strap depends on the material and level of care. A quality alligator strap, with regular but non-intensive use, retains its structural and aesthetic integrity for 2 to 4 years. Shell cordovan, due to its dense fibre structure, tends to last longer whilst developing a distinctive patina. Frequent exposure to water and perspiration accelerates deterioration; in such cases, alternating with a rubber or NATO strap is advisable.
