FAQ
What is the lug width of the Rolex Datejust 31 reference 278381rbr-0003?
The Rolex Datejust 31 ref. 278381rbr-0003 has a lug width of 16mm. This measurement should be taken with a digital calliper between the lugs at the spring bar hole to ensure a correct and precise strap fitting.
What is the best strap for the Rolex Datejust 31 278381rbr-0003?
For the Everose Rolesor version with a diamond-set bezel, a vegetable-tanned alligator strap is the most coherent aesthetic choice: the natural scale grain complements the brilliance of the stones without competing with them. Shades of burgundy, cognac, or gloss black pair accurately with the Everose 18ct gold case components.
How do you change the strap on a Rolex Datejust 31?
Strap replacement requires a fine-tipped spring bar tool to remove the spring bars from the 16mm lugs. The operation should be carried out carefully to avoid scratching the polished Everose gold lug finish. Casati Milano also offers in-atelier fitting by appointment.
Are there aftermarket straps compatible with the Rolex Datejust 31 ref. 278381rbr-0003?
Yes: any strap with a 16mm attachment and curved-end profile is technically compatible. Milano Straps offers handcrafted straps in alligator, calf leather, shell cordovan, and rubber, specifically made for the 16mm lug width, with finishes suited to the Rolesor Everose bi-metal case.
How long does a leather strap last on a Rolex Datejust 31?
Longevity depends on material and usage: a well-maintained vegetable-tanned alligator strap typically lasts 3 to 6 years with regular wear. Shell cordovan develops a natural patina over time and can exceed 5 years. Factors that shorten strap life include prolonged exposure to water, perspiration, and perfume. Milano Straps provides an 18-month warranty against manufacturing defects.
