FAQ

What is the lug width of the Rolex Datejust 31 178248-0080?

The Rolex Datejust 31 178248-0080 has a lug width of 16mm. This measurement is specific to the 31mm case diameter variant and requires straps cut or manufactured to this precise width. Before purchasing a replacement strap, it is advisable to verify the measurement using a digital calliper, measuring the internal gap between the lugs.

What is the best strap for the Rolex Datejust 31 178248-0080?

For the 18-carat yellow gold version, a belly-cut alligator strap is the most consistent choice with the case's luxury register. Cognac, tobacco, or midnight blue tones pair effectively with the classic dials of this model. Vegetable-tanned calf leather offers a more understated alternative with great character, developing a personal patina over time. A yellow gold deployant clasp completes the pairing with material coherence.

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

To replace the strap on the Datejust 31, the spring bars connecting the strap to the case lugs must be removed. The operation requires a fine-tipped or lever-style spring bar tool, inserted into the small notch on the side of each lug. It is recommended to work on a soft surface to protect the gold case. If in doubt, it is preferable to consult a watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Rolex Datejust 31 178248-0080?

Yes, high-quality aftermarket straps compatible with the Rolex Datejust 31 178248-0080 are available, provided they conform to the 16mm lug width and feature standard spring bars. Milano Straps offers a selection of handcrafted straps in various leathers and materials, manufactured with finishes and thicknesses suited to the 31mm yellow gold case. Each strap is produced using selected materials and artisanal quality control.

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

The lifespan of a leather strap depends on the material, frequency of use, and care applied. A quality alligator strap, worn regularly, will maintain its aesthetic and structural properties for 2 to 4 years. Vegetable-tanned calf leather, while less resistant to moisture, develops a distinguished patina and lasts similarly when treated with appropriate products. Milano Straps offers an 18-month guarantee against manufacturing defects on all handcrafted straps.
