Strap for Datejust 31 White Gold Fluted / President / Silver Diamonds & Sapphires

The Rolex Datejust 31 ref. 178279-0080 has a lug width of 16mm. This measurement corresponds to the internal distance between the case lugs and determines the exact strap width required. It is specific to the 31mm Datejust format, distinct from the 20mm lugs of the Datejust 41 and the 19mm lugs of the Datejust 36.

For the white gold case of the 178279-0080, a vegetable-tanned alligator strap is the most aesthetically coherent choice: the regular belly grain echoes the structure of the Fluted bezel. Shell cordovan develops a deep patina over time, while box calf leather in navy blue or burgundy offers maximum versatility for daily wear. The ideal closing hardware is an 18-carat white gold buckle or deployant clasp.

To replace the strap on the Datejust 31, a dedicated spring bar tool is required. The Datejust 31 uses spring bars that are removed from the side of the lug. Place the case on a soft cushion, release the outer spring bar first, then the inner one, and fit the new 16mm strap ensuring both spring bars click firmly into place. If in doubt, a watchmaker or the Casati Milano atelier can carry out the swap in a matter of minutes.

Yes. Any strap with a 16mm attachment is technically compatible with the Rolex Datejust 31 178279-0080. Milano Straps offers a curated range of handcrafted straps in alligator, calf leather, shell cordovan and rubber, made specifically for 16mm lugs, with customisable stitching, colours and finishes. High-quality aftermarket straps use vegetable-tanned leathers and saddlery threads, delivering superior aesthetics compared to factory straps.

The lifespan of a leather strap depends primarily on the quality of the hide, the tanning method and frequency of use. A high-grade vegetable-tanned alligator strap, worn in rotation with other watches, can last between 3 and 7 years while maintaining its structural and aesthetic integrity. Shell cordovan, owing to its dense fibre structure, is the most durable option. Standard calf leather typically lasts 1 to 3 years, while vulcanised rubber is virtually unaffected by moisture and intensive use. Milano Straps provides an 18-month warranty against manufacturing defects.
