Strap for Datejust 31 Rolesor Everose Domed Diamond / Jubilee / Pink Computer

The Rolex Datejust 31 ref. 178341-0047 has a lug width of 16mm. This measurement corresponds to the internal distance between the two lugs at the point where the strap attaches to the case. It can be verified using a digital calliper placed perpendicularly between the lugs, in contact with their inner surfaces.

For the Datejust 31 in Rolesor Everose, an alligator strap with Mississippi grain in cognac, burgundy or chocolate tones enhances the two-tone contrast of the case. Vegetable-tanned calf leather is the most versatile choice for daily wear, whilst shell cordovan develops a patina over time that complements the Everose gold bezel. A deployant clasp in steel with rose gold inserts provides the most coherent closure for this reference.

To replace the strap on the Datejust 31, a dual-tip springbar tool is required to release the spring bars housed in the 16mm lugs. Remove one end of the bar first, slide out the strap, then reverse the process to fit the new one. It is advisable to work on a soft surface to avoid scratching the case, and to have spare spring bars of the correct diameter for Rolex lugs to hand.

Yes. The Datejust 31 178341-0047 uses standard 16mm spring bars, making it compatible with any aftermarket strap built to that lug width. Milano Straps offers a selection of handcrafted 16mm straps in various materials and taper widths, finished with hand-stitched linings and burnished edges to ensure a precise fit and a quality on par with the original.

The lifespan of a leather strap depends on the material, care and frequency of use. A vegetable-tanned calf strap with daily wear typically lasts 18 to 24 months before showing structural wear at the keeper or fold area. Alligator, due to its dense fibre structure, generally lasts 3 to 5 years with periodic conditioning using a neutral cream. Shell cordovan often exceeds 5 years, developing a patina that improves its appearance over time. Avoiding prolonged contact with water and perspiration significantly extends the life of any leather strap.
