Strap for Datejust 31 Everose Domed / President / Pink Diamond

The Rolex Datejust 31 reference 178245f-0010 has a lug width of 16mm. This is a specific measurement that does not align with the most common strap widths (18mm or 20mm), so it is essential to use straps manufactured precisely to 16mm to ensure a correct fit without straining the Everose gold lugs.

For an Everose gold case, a polished alligator belly strap in burgundy, cognac, or dark chocolate provides the most coherent aesthetic pairing. Vegetable-tanned calf leather suits formal and professional settings, while vulcanised rubber is appropriate for active wear. A deployant clasp is recommended to distribute pressure evenly and extend the strap's service life.

To replace the strap on the Datejust 31, the spring bars connecting the strap to the case lugs must be released using a bifurcated spring bar tool inserted into the lug slot. The operation should be carried out on a soft surface to protect the polished surfaces of the rose gold case from scratching. If in doubt, it is advisable to entrust the task to a watchmaker or specialist atelier.

Yes. High-quality handcrafted aftermarket straps made specifically for the 16mm lug width of the Datejust 31 are available. Milanostraps.it offers models in alligator, calf leather, shell cordovan, and rubber, all built to the correct 16mm specification. The quality of craftsmanship and leather selection are the primary factors determining aesthetic result and longevity.

Longevity depends on leather type, frequency of wear, and maintenance. A quality alligator strap worn in rotation and kept away from moisture can maintain structural and aesthetic integrity for 2 to 4 years. Shell cordovan, owing to its dense fibre structure, tends to last longer whilst developing a distinctive patina. Vegetable-tanned calf leather responds well to conditioning with neutral cream. Prolonged exposure to water should be avoided with any leather strap.
