Datejust 31 278341rbr-0019— lug 16mm

The Rolex Datejust 31 ref. 278341rbr-0019 has a lug width of 16mm. This is the standard measurement for the entire Datejust 31 family, distinct from the 36mm version (20mm) and the Lady-Datejust 28mm (13mm). To verify the measurement, use a digital calliper positioned between the two lugs close to the case.

For the Datejust 31 in Rolesor Everose, an alligator strap with vegetable tanning is the most coherent choice: the belly grain complements the polished case finish and diamond-set details. Shell cordovan is the alternative for those seeking a developing patina over time. For daily or sport use, vulcanised rubber in rosé maintains chromatic coherence with the Everose gold.

The strap on the Datejust 31 is removed using a springbar tool, inserting the tip into the slot between the strap and the lug to compress the springbars. The operation takes approximately two minutes and does not require professional equipment, though it is advisable to work on a soft surface to avoid scratching the Rolesor Everose case.

Yes. Any strap with a 16mm attachment width is compatible with the Datejust 31 ref. 278341rbr-0019. Milano Straps handcrafted straps are produced with shaped ends to ensure a perfect fit against the curved lugs of the Datejust, with no gaps or visible spacing.

Longevity depends on the material and usage. An alligator strap with vegetable tanning, properly kept away from water and perspiration, lasts between 3 and 5 years with daily wear. Shell cordovan, being denser and more compact, can exceed 5 years while developing a patina that enhances its appearance. Milano Straps guarantees all its straps for 18 months against manufacturing defects.
