Strap for Datejust 31 Rose Gold / Domed / Rose - Roman / Oyster

The Rolex Datejust 31 reference 278245-0033 features a lug width of 16mm. This measurement is specific to the 31mm case size and must be verified before purchasing any aftermarket or replacement strap.

For the Datejust 31 in rose gold, a vegetable-tanned alligator strap is the most coherent choice for the watch's formal register. Warm tones such as bordeaux, tobacco or cognac complement the Everose gold beautifully. Smooth calfskin offers a more understated profile, while shell cordovan provides superior durability and a patina that improves with age.

Replacing the strap on the Datejust 31 requires a compatible 16mm spring bar and a fine-tipped springbar tool. Remove the spring bars from the lugs carefully to avoid scratching the rose gold surfaces. It is advisable to work on a soft pad and, if in doubt, to consult a watchmaker or the Casati Milano atelier.

The lifespan of a leather strap depends on the quality of the hide and conditions of use. A high-quality alligator or shell cordovan strap, properly maintained and not regularly exposed to water or perspiration, can last between three and six years while retaining its structure and appearance. Casati Milano straps carry an 18-month warranty against manufacturing defects.
