Strap for Datejust 31 Everose Fluted / President / Pink Diamonds

The Rolex Datejust 31 ref. 178275f-0008 has a lug width of 16mm. This measurement should be taken with a digital calliper across the internal distance between the two lugs at the bottom of the case. It is a specific dimension: straps of 17mm or 18mm are not compatible and forcing them risks damaging the 18-carat Everose gold lugs.

For a Datejust 31 in Everose gold, a vegetable-tanned alligator strap — in cognac, burgundy or black — is the most coherent choice given the piece's positioning. A boxy calfskin strap is a more understated alternative. In sporting or summer contexts, vulcanised rubber ensures comfort and water resistance. A deployant clasp in rose gold completes any pairing with elegance and security.

The strap on a Rolex Datejust 31 is removed using a springbar tool inserted into the hole on the lug. Apply gentle leverage to compress the springbars and slide the strap free. No watchmaker intervention is required if the correct tool is used and the work is carried out on a soft surface to protect the Everose gold case from scratches.

Yes. Any strap with a 16mm attachment is technically compatible with the Datejust 31. The selection of handcrafted aftermarket straps available on milanostraps.it for 16mm lug width includes models in alligator, calfskin, shell cordovan and technical materials, all fitted with standard 1.8mm springbars compatible with Rolex lugs.

Longevity depends on the type of leather, the tanning method and conditions of use. A quality vegetable-tanned alligator strap, worn with care — avoiding prolonged contact with water, perspiration and perfume — typically lasts between 2 and 5 years whilst developing a fine patina. Shell cordovan, owing to its dense fibre structure, is among the most durable materials and can exceed 4 to 6 years. Lacquered or patent-finished straps have a shorter lifespan compared to oiled or waxed leathers.
