Strap for Datejust 31 Stainless Steel Domed Diamond / Jubilee / Pink - Diamond

The lug width of the Rolex Datejust 31 178344-0023 is 16 millimetres. This dimension is specific to the 31mm Datejust models and represents the distance between the two lugs at the extremities of the case where the strap is attached.

The best strap depends on intended use and personal preference. For formal and sophisticated use, alligator in natural or cognac tones represents the most elegant choice. For versatile everyday wear, vegetable-tanned calf leather offers comfort and natural patina development. For summer months, a rubber strap or woven NATO ensures practicality without aesthetic compromise.

Changing the Datejust 31 strap requires the use of specific tools (spring bar tool and replacement pins) and precision. We recommend consulting an authorised Rolex dealer or specialised expert. At our Casati Milano atelier, we perform this operation with the utmost care, preserving the integrity of the case.

Yes, it is possible to fit a high-quality aftermarket strap provided it is correctly sized for a 16mm lug width. An artisanal strap crafted with premium leathers and sartorial techniques elevates the watch's elegance further and enables customisations impossible with OEM straps.

A high-quality leather strap, made with vegetable tanning and properly maintained, lasts 3–5 years before requiring replacement. Longevity depends on use frequency, exposure to perspiration and humidity, and maintenance practices. Premium leathers such as alligator or shell cordovan age beautifully, developing a refined patina over time.
