Strap for Datejust 31 Stainless Steel/ Rose Gold / Diamond / Rose - Diamond / Oyster

The Rolex Datejust 31 ref. 278381rbr-0023 has a lug width of 16mm. This measurement is specific to the 31mm variants of the Datejust family and differs from the 36mm (20mm) and 41mm (21mm) versions. To verify it, measure the internal space between the lugs at the case junction using a digital calliper.

For the Datejust 31 in Rolesor Everose, straps in vegetable-tanned alligator or Swift calfskin offer the most coherent pairing with the mother-of-pearl dial and diamond-set bezel. Shades of burgundy, cognac and midnight blue complement the warm tones of Everose gold. All straps must have a 16mm attachment width.

To replace the strap on the Datejust 31, you will need a spring bar tool or a fork-style strap changing tool. The 16mm spring bars must be removed carefully to avoid scratching the Everose gold lugs. It is advisable to work on a soft watchmaker's pad, and if in doubt, to entrust the operation to a qualified watchmaker or the Casati Milano atelier service.

Yes. The Datejust 31 ref. 278381rbr-0023 accepts any strap with a standard 16mm spring bar attachment. Milano Straps offers a selection of handcrafted straps in alligator, calfskin, shell cordovan and rubber specifically made for this lug width, with tapers and lengths calibrated for slimmer and medium wrists.

The lifespan of a leather strap depends on the quality of the tanning, frequency of use, and exposure to perspiration and moisture. A quality vegetable-tanned alligator strap, used with care and rotated with a second strap, can maintain its structural integrity for 3 to 5 years whilst developing an attractive patina. Calfskin straps generally last 2 to 3 years with daily wear.
