FAQ
What is the lug width of the Rolex Datejust 31 reference 178343-0025?
The Rolex Datejust 31 ref. 178343-0025 has a lug width of 16mm. This measurement refers to the internal distance between the two lower lugs at the point where the strap attaches to the case. It is specific to this model family and should be verified with a digital calliper before purchasing any aftermarket strap.
What is the best strap for the Rolex Datejust 31 178343-0025?
For the Datejust 31 178343-0025 in Yellow Rolesor, the most appropriate options are: alligator in dark brown or midnight blue for formal pairings, naturally tanned calfskin for those seeking an organic patina over time, and shell cordovan in burgundy or cognac for a compact, durable texture. A deployant clasp in steel or gold PVD ensures visual symmetry with the two-tone case.
How do you change the strap on a Rolex Datejust 31?
To replace the strap on a Datejust 31, a fine-tipped spring bar tool is required. Insert the tool into the lug hole to compress the spring bar and release the strap. With 16mm lugs, it is essential to use spring bars of the correct diameter for the Rolex case. Care must be taken to avoid scratching the case during the operation; if in doubt, it is advisable to contact a watchmaker or the Casati Milano atelier.
Are there aftermarket straps compatible with the Rolex Datejust 31 178343-0025?
Yes. Milanostraps.it offers a selection of handcrafted aftermarket straps with a 16mm attachment, compatible with the Rolex Datejust 31 ref. 178343-0025. The straps are made to measure or selected from standard sizes, with stitching and finishing appropriate to the level of the timepiece.

How long does a leather strap last on a Rolex Datejust 31?
Longevity depends on the material and daily use. A quality alligator strap, kept away from water and excessive perspiration, maintains structural and aesthetic integrity for 3 to 5 years. Naturally tanned calfskin offers a similar lifespan, with the added benefit of developing a personal patina over time. Shell cordovan is the most resistant to repeated flexing and can last over 5 years. Casati Milano offers an 18-month warranty against manufacturing defects on all straps crafted in the atelier.
