Frequently asked questions
What is the lug width of the Rolex Datejust 31 178271-0032?
The lug width of the Rolex Datejust 31 178271-0032 is 16mm. This measurement should be taken with a digital calliper at the inner distance between the lugs at the point of attachment to the case. It is specific to the Datejust 31 and is not shared with other diameters within the same family.
What is the best strap for the Rolex Datejust 31 178271-0032?
For the Datejust 31 178271-0032 with its Everose gold bezel and mother-of-pearl dial, a vegetable-tanned alligator strap in cognac, bordeaux or tobacco tones is the most aesthetically coherent choice. The leather develops a natural patina over time and its scale texture complements the iridescent surface of the mother-of-pearl dial. A deployant clasp in rose gold or steel completes the pairing with elegance.
How do you change the strap on a Rolex Datejust 31?
To replace the strap on a Rolex Datejust 31, you will need a flat-tipped spring bar tool or a watchmaker's screwdriver. The spring bars are compressed laterally to release the strap from the lugs. Care must be taken not to scratch the steel case or the rose gold lugs. If in doubt, it is advisable to consult a watchmaker or the Casati Milano atelier.
Are there aftermarket straps compatible with the Rolex Datejust 31 178271-0032?

How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on the quality of the hide, the tanning method and daily use. A vegetable-tanned alligator strap of artisanal quality, with proper care — avoiding prolonged exposure to perspiration and water, and conditioning the leather periodically — will last between 2 and 5 years with regular wear. Milano Straps straps are covered by an 18-month guarantee against manufacturing defects.
