Strap for Datejust 31 Rolesor Everose Domed Diamond / Oyster / Chocolate Roman

The Rolex Datejust 31 reference 178341-0010 has a lug width of 16mm. This measurement should be taken internally between the two lugs using a digital calliper placed directly against the case, ensuring accuracy before purchasing an aftermarket strap.

For the Datejust 31 178341-0010 in Rolesor Everose, the most suitable materials are belly alligator in cognac or bordeaux, vegetable-tanned calf leather in Chevre grain, and shell cordovan. These materials complement the warm tones of the Everose gold and pair well with both light and dark dials. A deployant clasp in steel or rose gold is recommended to preserve the longevity of a leather strap.

To remove the original strap from the Datejust 31 178341-0010, a dedicated springbar tool or a fine flathead screwdriver is required. The lugs on this model accept springbars with a diameter of 1.8mm. It is advisable to work on a soft surface to avoid scratching the case, and to avoid applying lateral force to the lugs when removing the springbars.

Yes. Any strap with a 16mm lug width and straight or slightly curved ends is compatible with the Datejust 31 178341-0010. A dedicated selection of 16mm straps in various materials and finishes is available on milanostraps.it. For an optimal fit, it is advisable to specify the lug curvature when placing a bespoke order at the Casati Milano atelier.

The lifespan of a leather strap depends on the material, frequency of use, and maintenance. A quality alligator strap with vegetable tanning, worn daily, has an average lifespan of 2 to 4 years. Shell cordovan, due to its structural density, can last over 5 years with regular care. Using a deployant clasp significantly reduces wear at the buckle area, extending the overall life of the strap.
