FAQ
What is the lug width of the Rolex Datejust 31 178159-0014?
The Rolex Datejust 31 ref. 178159-0014 has a lug width of 16mm. This non-standard measurement requires straps specifically cut to 16mm to ensure a precise fit between the lugs and the strap, preventing mechanical play and premature wear.
What is the best strap for the Rolex Datejust 31 178159-0014?
For a white gold case of 31mm diameter, the most suitable straps are polished alligator (black or midnight blue for formal occasions) or shell cordovan for intensive daily wear. Vegetable-tanned calf leather in neutral tones is an excellent alternative for a less formal register. The lug width is 16mm.
How do you change the strap on the Rolex Datejust 31 178159-0014?
To replace the strap, a spring bar tool is required to remove the spring bars securing the strap to the case lugs. The procedure is straightforward but demands care to avoid scratching the white gold case. 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 178159-0014?
Yes. Milanostraps.it offers a selection of handcrafted aftermarket straps in 16mm lug width compatible with the Datejust 31 178159-0014. Straps are crafted to measure using selected leathers and are available in various finishes, with a full bespoke option through the Casati Milano atelier.
How long does a leather strap last on a Rolex Datejust 31?
Longevity depends on the material and usage conditions. A shell cordovan strap with vegetable tanning can last 5–10 years when cared for properly and kept away from prolonged moisture and perspiration. Premium alligator leather offers comparable durability. All Casati Milano straps carry an 18-month warranty against manufacturing defects.
