Strap for Datejust 31 Stainless Steel/ Rose Gold / Fluted / White - Roman / Oyster

The lug width of the Rolex Datejust 31 ref. 278271-0001 is 16 millimetres. This dimension is specific to the 31mm Datejust models and is determined by the proportion between the case diameter and the thickness of the lugs. To verify the compatibility of an aftermarket strap, measure the internal distance between the two lugs using a digital calliper: it must be exactly 16mm.

For the Datejust 31 278271-0001, straps in alligator, vegetable-tanned calf or shell cordovan are recommended. Alligator offers formal elegance with its characteristic longitudinal grain and enhances the Rolesor Everose two-tone aesthetic. Vegetable-tanned calf is more versatile and develops a beautiful patina over time. Shell cordovan is the premium choice for those seeking an exceptionally dense leather that gains lustre and character with age. All these materials are available from Milano Straps in various colour options.

To change the strap on the Datejust 31, you will need a spring bar removal tool or to consult a qualified watchmaker. Place the watch on a soft cushion to protect it from scratches. Locate the small elastic pins connecting the strap to the lugs, insert the tool into the lateral groove to compress the pin, and slide off the old strap. Repeat for the other side. Proceed in reverse to position the new strap with 16mm lug width, ensuring the pins lock securely into the lugs.

Yes, the Rolex Datejust 31 278271-0001 is fully compatible with aftermarket straps featuring 16mm lug width. Straps crafted by specialist artisans often offer superior quality to original Rolex straps, with carefully selected leathers, refined finishing and bespoke workmanship. Milano Straps offers a curated selection of high-quality artisanal straps in various materials, colours and styles. It is important to ensure that the lug width is exactly 16mm to guarantee proper fit on the watch lugs.

A quality leather strap, such as those crafted by Casati Milano, typically lasts between 3 and 7 years depending on frequency of wear, leather quality, tanning method and maintenance. A well-made vegetable-tanned calf can last 5-7 years if the watch is not worn daily. Shell cordovan, being denser leather, is even more durable. Alligator offers intermediate longevity. All artisanal straps from Milano Straps include an 18-month warranty against manufacturing defects. Longevity increases significantly if the strap is properly dried after moisture contact and stored away from direct sunlight when not worn.
