FAQ

What is the lug width of the Rolex Datejust 31 278273-0013?

The Rolex Datejust 31 ref. 278273-0013 has a lug width of 16 mm. This measurement is taken from the inner distance between the two lugs of the 31 mm Oyster case and is the key specification for selecting a compatible aftermarket strap. It is always advisable to verify this with a calliper before purchasing.

What is the best strap for the Rolex Datejust 31 278273-0013?

For the Datejust 31 in yellow gold and steel Rolesor, the most suitable straps are alligator belly in cognac or tobacco brown, which complement the warmth of the yellow gold, or box calf leather for a more understated everyday look. Those seeking water resistance may opt for vulcanised rubber with a deployant clasp. All straps must have a 16 mm end width.

How do I change the strap on a Rolex Datejust 31 278273-0013?

To replace the strap on the Datejust 31, a dual-tip springbar tool is required to remove the springbars from the Oyster case lugs. Place the watch on a soft cloth, work carefully to avoid scratching the polished surfaces, and ensure the replacement springbars have the appropriate diameter for Rolex lug depth (typically 1.8 mm).

Are there aftermarket straps compatible with the Rolex Datejust 31 278273-0013?

Yes. Aftermarket straps compatible with the Datejust 31 ref. 278273-0013 must have a 16 mm lug width and a standard length suited to a female wrist (typically 105/65 mm). Milanostraps.it offers a curated selection of handcrafted straps in various leathers and materials, all made to this specific dimension, with bespoke customisation available through the Casati Milano atelier.

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

The lifespan of a leather strap depends on the quality of the tanning process, daily use and care. A high-quality alligator or calf strap with artisanal finishing can last between 2 and 5 years with regular wear. Prolonged exposure to perspiration, water and perfume accelerates wear. Milanostraps.it provides an 18-month guarantee against manufacturing defects on all its straps.
