Strap for Datejust 31 White Gold Fluted / President / Pink MOP Roman

The Rolex Datejust 31 reference 178279-0058 has a lug width of 16mm. This measurement is standard across the entire Datejust 31mm family and requires straps specifically cut to this width. Using a strap of a different size would compromise the alignment with the case and the functionality of the buckle.

For a white gold case such as that of the Datejust 31 178279-0058, vegetable-tanned alligator leather represents the most coherent pairing: the natural grain of the scales complements the precious case without visual overload. Shell cordovan offers a compact surface and superior longevity as an alternative. For more dynamic daily use, smooth calf leather or vulcanised rubber are functionally sound options.

Replacing the strap on a Datejust 31 requires a spring bar tool — a forked instrument that compresses the ends of the spring bar housed within the lug. Care must be taken not to scratch the white gold case during the operation: it is advisable to protect the lugs with PTFE tape or to entrust the task to a watchmaker. The replacement strap must have a 16mm attachment to ensure correct fitting.

Yes. Aftermarket straps with a 16mm attachment are fully compatible with the Datejust 31, provided they are built with standard 1.5mm diameter spring bars and the strap end is trimmed to follow the curve of the Rolex lug. Milanostraps.it offers a selection of handcrafted 16mm straps specifically worked to match this case profile.

Longevity depends on the type of leather, frequency of use, and routine care. A quality alligator strap, kept away from prolonged moisture and periodically conditioned with leather cream, maintains structural and aesthetic integrity for 3 to 6 years with daily wear. Shell cordovan, due to the density of its fibres, tends to last considerably longer. Frequent exposure to perspiration or water significantly reduces the service life of any leather strap.
