Datejust 31 178271-0072— lug 16mm

The Rolex Datejust 31 ref. 178271-0072 has a lug width of 16mm. This measurement is specific to the 31mm case diameter and is essential when selecting any replacement strap, whether an original Rolex bracelet (Jubilee or Oyster) or an aftermarket handcrafted strap.

For the Datejust 31 in Rolesor Everose, a glossy alligator strap in burgundy, chocolate or midnight blue enhances the rose gold case. Alternatively, vegetable-tanned calf leather or shell cordovan develop a natural patina and offer exceptional longevity. The ideal choice depends on the intended use: formal, everyday or casual-sport.

Changing the strap requires a fine-tipped spring bar tool inserted into the slot between the lug and the strap end to release the spring bars. Work on a soft watch mat to protect the case from scratches. For aftermarket straps with curved ends tailored to this case, the fitting process is identical but requires correctly profiled ends for the 16mm lug.

Yes. Milano Straps manufactures and retails handcrafted aftermarket straps with a 16mm lug width compatible with this reference. Available materials include alligator, vegetable-tanned calf leather, shell cordovan and rubber, with buckle or deployant clasp options. Bespoke commissions are handled by Casati Milano atelier for a fully personalised fit and aesthetic.

The lifespan of a leather strap depends on the material and daily care. A quality alligator strap with vegetable tanning, kept away from prolonged moisture and treated periodically with leather conditioner, can last between 3 and 7 years with regular wear. Shell cordovan, owing to its dense and waxy structure, typically offers superior durability. Milano Straps provides an 18-month warranty against manufacturing defects on all straps.
