Strap for Datejust 31 Stainless Steel/ Rose Gold / Domed - Diamond / Silver - Diamond / Jubilee

The Rolex Datejust 31 ref. 278341rbr-0016 features a lug width of 16mm. This measurement is taken with a digital calliper between the two lugs at the point where they meet the case. It is specific to this 31mm reference and is not interchangeable with straps designed for the 28mm or 36mm versions of the Datejust family.

For an Everose Rolesor case with a diamond-set bezel, a semi-gloss Louisiana alligator strap in burgundy, cognac or black provides the most coherent aesthetic pairing. Shell cordovan is recommended for those seeking a more understated patina and superior longevity. Vegetable-tanned calf leather suits everyday wear, while vulcanised rubber is ideal for sport or marine environments. A deployant clasp in steel or 18k rose gold completes the fitting with secure and precise closure.

Strap replacement requires a dedicated spring bar tool compatible with the 1.5mm diameter spring bars used by Rolex. Insert the tip into the spring bar slot, compress laterally and carefully slide the strap free, taking care not to scratch the Rolesor Everose case. Given the mixed-metal finish, only properly padded tools should be used. If in doubt, the Casati Milano atelier offers professional assistance.

Yes. Aftermarket straps with a 16mm attachment and curved ends (radius 1.8–2mm) are fully compatible with the Datejust 31 278341rbr-0016. milanostraps.it offers a curated selection of handcrafted straps in alligator, shell cordovan, calf leather and rubber, made to measure for this lug width. The tail width typically ranges from 14mm to 16mm depending on aesthetic preference.

Longevity depends on leather quality, tanning method and frequency of wear. A vegetable-tanned alligator strap worn in regular rotation can retain its structure and colour for 3–5 years. Shell cordovan, owing to its dense fibre structure, may exceed 5 years while developing a desirable patina. Good-quality smooth calf leather typically lasts 2–3 years. Prolonged exposure to perspiration, water and direct sunlight should be avoided to extend strap life.
