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

The lug width of the Rolex Datejust 31 ref. 278341rbr-0009 is 16mm. This measurement refers to the internal distance between the two lugs at the point where the strap attaches to the case and is the correct specification to request when sourcing any compatible aftermarket strap.

For the Datejust 31 in Rolesor Everose, a vegetable-tanned alligator strap in bordeaux, tobacco brown or midnight blue is the most coherent choice given the model's positioning. Alternatively, a grained calf leather or vulcanised rubber strap offers versatility for less formal settings. A deployant clasp in rose gold or steel completes the pairing whilst protecting the strap from excessive wear.

To replace the strap on the Datejust 31, a fine-tipped spring bar tool is required. The two spring bars securing the strap to the case lugs are removed carefully to avoid scratching the rose gold or steel surfaces. It is advisable to have this operation carried out by a watchmaker or specialist atelier such as Casati Milano to preserve the integrity of the lugs.

Yes. The Rolex Datejust 31 ref. 278341rbr-0009 accepts any aftermarket strap with a 16mm lug width and standard spring bars. milanostraps.it offers a curated selection of handcrafted straps in alligator, calf leather, shell cordovan and rubber, specifically calibrated to this size, with bespoke customisation available through the Casati Milano atelier.

The lifespan of a leather strap depends on the quality of the hide, the tanning method and daily usage. A high-quality vegetable-tanned alligator strap, with proper care, typically lasts between 2 and 4 years with regular wear. Shell cordovan, owing to its dense fibrous structure, tends to outlast most other leathers. Prolonged exposure to water, perspiration and heat accelerates deterioration; rotating between straps and avoiding contact with liquids is strongly recommended.
