Strap for Datejust 31 Rose Gold / Fluted / Rose / Oyster

The lug width of the Rolex Datejust 31 reference 278275-0036 is 16mm. This measurement should be taken internally between the two lugs using a digital calliper, in contact with the case. Any standard 16mm aftermarket strap is compatible with this reference.

For a Datejust 31 in Everose gold, a vegetable-tanned alligator strap in bordeaux or burnished tobacco tones is the most coherent pairing. Smooth calfskin is a practical alternative for daily wear, while a NATO nylon strap offers a deliberate stylistic contrast for casual settings. The final choice depends on intended use and the dial variant.

To replace the strap on a Rolex Datejust 31, use a flat-blade screwdriver or a springbar tool to remove the spring bars securing the strap to the lugs. The process is straightforward but requires care to avoid scratching the gold lugs. It is advisable to work on a soft cloth and, if in doubt, consult a watchmaker or the Casati Milano bespoke service.

The lifespan of a leather strap depends on the material, maintenance, and frequency of use. A quality vegetable-tanned alligator strap, kept away from water and excessive perspiration, can last between two and five years with regular wear. Calfskin typically has a shorter lifespan but offers greater versatility. Periodic cleaning and the application of a leather conditioner will significantly extend the strap's life.
