Yes, numerous artisan manufacturers produce aftermarket straps for 16mm lug width that are fully compatible with the Datejust 31 178274-0018. It is essential to verify that the declared width is exactly 16mm, that the included spring bars have the correct diameter for Rolex lugs, and that the taper of the strap is proportionate to the 31mm case diameter.

The lifespan of a leather strap on a Rolex Datejust 31 depends on the quality of the tanning process and daily usage conditions. A high-quality alligator or shell cordovan strap, with regular use but kept away from prolonged moisture exposure, typically lasts between 2 and 4 years before wear affects its appearance. Vegetable-tanned calf leather tends to have a shorter lifespan but develops a personal patina that many enthusiasts find appealing.
