The Datejust 31 178271-0072, seen from the bench

The Rolex Datejust 31 ref. 178271-0072 combines a bicolor Rolesor Everose case—stainless steel paired with 18k rose gold—with a mother-of-pearl dial set with diamonds. Powered by the Rolex 2235 automatic movement beating at 28,800 bph with approximately 48 hours power reserve, it is COSC certified. The 31mm case is water-resistant to 100 meters and features a fluted rose gold bezel and sapphire crystal with anti-reflective coating. The 16mm lug width is specific to this diameter and requires precise measurement for compatible aftermarket straps.

Frequently asked questions

What is the lug width of the Rolex Datejust 31 ref. 178271-0072?

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.

What is the best strap for the Rolex Datejust 31 178271-0072?

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.

How do I change the strap on a Rolex Datejust 31?

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.

Are there aftermarket straps compatible with the Rolex Datejust 31 178271-0072?

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.

How long does a leather strap last on a Rolex Datejust 31?

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.
