FAQ
What is the lug width of the Rolex Datejust 31 reference 178341-0045?
The Rolex Datejust 31 ref. 178341-0045 features a lug width of 16mm. This measurement is consistent across the entire Datejust 31 range and should be verified with a digital calliper before purchasing any aftermarket strap.
What is the best strap for the Rolex Datejust 31 178341-0045?
For the Datejust 31 in Rolesor Everose, a vegetable-tanned alligator strap in cognac or deep burgundy tones offers the closest aesthetic harmony with the case materials. Box calf leather and shell cordovan are strong alternatives for a more contemporary or individual look. The 16mm lug width requires straps specifically produced for this size.
How do you change the strap on a Rolex Datejust 31 ref. 178341-0045?
Strap replacement requires a double-ended spring bar tool to release the spring bars from the 16mm lugs. Work on a soft surface to protect the Rolesor case and bezel. If in doubt, entrust the operation to a watchmaker or specialist atelier to avoid scratching the case.
Are there aftermarket straps compatible with the Rolex Datejust 31 178341-0045?
Yes. Several artisan manufacturers produce straps with a 16mm lug width compatible with the Datejust 31. Milano Straps offers a curated selection of 16mm straps in leather, rubber and textile, with a fully bespoke option available through Casati Milano atelier.
How long does a leather strap last on a Rolex Datejust 31?
The lifespan of a leather strap depends on the material, frequency of wear and maintenance. A quality vegetable-tanned alligator strap, rotated with at least one other strap and kept away from moisture, can last between 3 and 7 years while retaining its patina and structure. Shell cordovan tends to last even longer due to its dense fibre composition. Milano Straps covers manufacturing defects for 18 months.
