Strap for Datejust 31 Everose Fluted / President / MOP Roman

The lug width of the Rolex Datejust 31 178275f-0026 is 16mm. This measurement should be taken using a calliper positioned between the two lugs of the case, parallel to the strap seat. Adhering precisely to this dimension is essential to ensure a correct fit without lateral play.

For the Datejust 31 in Everose gold, the most suitable straps are in alligator belly in cognac or burgundy tones — which complement the warmth of the Everose alloy — or in shell cordovan, which develops a distinctive personal patina over time. For everyday use, a vegetable-tanned calf leather strap with a grain finish offers durability and versatility. The buckle or deployant clasp should be in 16mm rose gold to maintain chromatic continuity with the case.

To replace the strap on the Datejust 31 178275f-0026, a springbar tool designed for closed lugs is required. Insert the tip of the tool into the lateral slot of the lug, compress the spring bar inward and slide the strap free. Care should be taken to avoid scratching the Everose gold case: it is advisable to protect the surfaces with masking tape before proceeding.

Yes, a wide range of aftermarket straps are compatible with the Datejust 31 178275f-0026, provided they respect the 16mm lug width and feature straight or slightly curved ends suited to the Everose case profile. Milano Straps offers handcrafted straps in leather, alligator, shell cordovan and rubber, made to measure for this model, with rose gold buckles available for a coherent chromatic match.

The lifespan of a leather strap depends on the quality of the materials and frequency of use. A high-quality handcrafted alligator or shell cordovan strap, vegetable-tanned and hand-finished, can last between 3 and 6 years with regular use, developing a distinctive patina over time. Prolonged exposure to water and perspiration accelerates deterioration: it is advisable to avoid wearing the strap in rain and to rotate between multiple straps to extend their life.
