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

The Rolex Datejust 31 ref. 278241-0001 has a lug width of 16mm. This measurement is taken internally between the two case lugs using a digital calliper, positioned against the case rather than the spring bars. For the best aesthetic result, straps with curved or semi-curved ends are recommended, as these are specifically shaped to match the Datejust lug profile.

For the Datejust 31 in Rolesor Everose, an alligator strap in vegetable-tanned leather with an Everose gold deployant clasp is the most coherent choice for this timepiece. The belly alligator grain complements the fluted bezel, whilst tones such as burgundy, natural cognac or midnight blue enhance the warm notes of Everose gold. For more casual wear, box-grain calf leather or a slim vulcanised rubber strap are sound alternatives.

The Datejust 31 strap is secured to the case with standard 1.5mm spring bars. To replace the strap, use a fine-tipped spring bar tool, inserting it into the slot on the inner side of the lug to compress the spring bar and release the strap. No specialist tools or watchmaker assistance are required, though it is advisable to work on a soft surface to protect the case finishing.

Yes, the aftermarket offers a wide range of straps compatible with the Datejust 31 at a 16mm lug width. The Milano Straps selection includes alligator, calf leather, shell cordovan and rubber models specifically crafted for the Datejust lug profile. It is important to verify that the chosen strap features curved or semi-curved ends to ensure proper fit against the case and a result in keeping with manufacture standards.

The lifespan of a leather strap depends on the material, tanning process and frequency of use. A high-quality vegetable-tanned alligator strap, properly maintained with a neutral leather conditioner and rotated with other straps, can last between three and six years whilst retaining a lively patina and structural integrity. Prolonged contact with water, perspiration and perfume accelerates deterioration: it is always advisable to remove a leather strap during sport or in humid environments.
