Frequently asked questions

What is the lug width of the Rolex Datejust 31 278341RBR-0032?

The Rolex Datejust 31 278341RBR-0032 has a lug width of 16mm. This measurement is specific to the 31mm case size and differs from the 36mm and 41mm Datejust variants, which use 20mm lugs. Any replacement strap must match this dimension precisely to ensure a secure and play-free fit.

What is the best strap for the Rolex Datejust 31 278341RBR-0032?

For an Everose Rolesor case with a diamond-set bezel, an alligator strap in bordeaux or cognac is the most aesthetically coherent choice: it complements the rose gold without competing with the bezel. Alternatively, vegetable-tanned calf leather or shell cordovan in dark tones offer versatile everyday wear with artisanal character. Lug width: 16mm.

How do you change the strap on a Rolex Datejust 31 278341RBR-0032?

The strap is removed using a spring bar tool to extract the two spring bars seated in the 16mm lugs. No Rolex-specific tools are required for standard aftermarket straps. It is advisable to work on a soft surface to avoid scratching the Everose Rolesor case and to verify correct spring bar tension before wearing the watch.

Are there aftermarket straps compatible with the Rolex Datejust 31 278341RBR-0032?

Yes. The Datejust 31 278341RBR-0032 accepts any strap with a 16mm attachment and standard spring bars. Milano Straps artisanal straps in alligator, calf leather, shell cordovan and other materials are made specifically for this lug width and are directly compatible without any case modification.

How long does a leather strap last on a Rolex Datejust 31?

The lifespan of a leather strap depends on the material, frequency of use and care. A quality artisanal alligator strap, properly stored and rotated with other straps, can last between 3 and 5 years. Vegetable-tanned calf leather develops a patina over time but is more sensitive to moisture. Shell cordovan is the most durable among traditional leathers. Milano Straps offers an 18-month warranty against manufacturing defects.
