Strap for Datejust 31 Rolesor Everose Domed Diamond / Jubilee / Pink

The lug width of the Rolex Datejust 31 178341-0023 is 16 millimetres. This measurement represents the internal space between the spring bar pins that attach the strap to the case lugs. Always verify this dimension before purchasing an aftermarket strap, as an incorrect width will result in impossible or unstable fitting.

For the Datejust 31 178341-0023, we recommend alligator leather or vegetable-tanned calf, which complement the Everose gold beautifully. Alligator offers superior durability and water resistance; vegetable-tanned calf develops a natural patina over time. Alternatively, rubber or technical fabric straps provide a more contemporary and sporty character.

To change the strap on your Datejust 31 178341-0023, you need a spring bar tool. Insert the tool under the spring bar pin, gently push downward to release the internal spring, then remove the pin. Repeat on the opposite lug. Align the new strap's holes with the case lugs and insert the pins until you hear a click. If uncertain, consult a professional watchmaker.

Yes, any bespoke or manufactured strap with a 16mm lug width is compatible with the Datejust 31 178341-0023. Always verify that the strap's spring bar pins match the standard diameter (approximately 1.5–1.6mm). Milano Straps bespoke designs are crafted to Rolex technical specifications and install without modification.

The lifespan of a leather strap depends on daily wear and maintenance practices. A quality alligator or calf strap, worn regularly, typically lasts 3–5 years before significant wear becomes visible. Vegetable-tanned leather can last longer if properly maintained—periodic cleaning and protection from moisture and direct sunlight are essential. Milano Straps bespoke designs carry an 18-month warranty against manufacturing defects.
