FAQ
What is the lug width of the Rolex Datejust 31 ref. 278271-0006?
The Rolex Datejust 31 ref. 278271-0006 has a lug width of 16mm. This measurement refers to the internal distance between the two lugs of the case and must be confirmed before purchasing any aftermarket strap. It is a consistent specification across the entire Datejust 31 family, regardless of dial variant or case material combination.
What is the best strap for the Rolex Datejust 31 278271-0006?
For the two-tone Everose-Oystersteel case of the Datejust 31, an alligator strap in vegetable-tanned leather in cognac or dark brown is the most coherent choice: it enhances the rose gold reflections and develops a natural patina over time. Shell cordovan in black or box-calf calf leather are excellent high-durability alternatives for those who prefer a more understated aesthetic. In all cases, the 16mm lug width is the essential technical parameter for compatibility.
How do you change the strap on a Rolex Datejust 31?
Changing the strap on a Datejust 31 requires a flat-blade screwdriver or a 1.5mm springbar tool, inserted into the designated lug slots to compress the springbars. It is advisable to work on a soft surface to protect the case and to ensure that the new springbars have the correct diameter and length for the 16mm lugs. If in doubt, it is best to consult a watchmaker or the Casati Milano atelier.
Are there aftermarket straps compatible with the Rolex Datejust 31 278271-0006?
Yes. Compatible aftermarket straps must conform to the 16mm lug width and fit standard springbars. Milano Straps offers a curated selection of handcrafted straps in alligator, calf leather, shell cordovan and rubber, specifically sized for the 16mm lugs of the Datejust 31. The quality of materials and artisanal construction ensure a fit and aesthetic that are comparable — and often superior — to factory straps.
How long does a leather strap last on the Rolex Datejust 31?
The lifespan of a leather strap depends on the material, care, and daily use. A quality vegetable-tanned alligator strap, with periodic conditioning and rotation between multiple straps, typically lasts between 3 and 6 years. Shell cordovan, owing to the exceptional density of its fibres, can exceed 5 to 8 years. Box-calf straps fall in the 2–4 year range. All Milano Straps products are covered by an 18-month warranty against manufacturing defects.
