Strap for Datejust 31 Stainless Steel Fluted / Jubilee / Grey - Roman

The lug width of the Rolex Datejust 31 278274-0022 is 16mm. This measurement should be taken with a digital calliper between the inner edges of the case lugs at their narrowest point, to ensure correct compatibility with aftermarket straps.

For the Datejust 31 278274-0022, with its stainless steel and white gold case, a smooth-grain alligator strap is the most coherent choice given the model's formal character. Shell cordovan and vegetable-tanned calf leather are strong alternatives offering durability and a refined aesthetic. A deployant clasp is recommended to preserve the strap over time.

To replace the strap on the Datejust 31 278274-0022, use a fine-tipped spring bar tool. Insert the tip into the slot at the side of the lug, compress the spring bar and slide the strap free. Take care not to scratch the case. If in doubt, consult a watchmaker or the Casati Milano atelier.

The lifespan of a leather strap depends on material and care. A quality alligator strap worn regularly will typically last 2–4 years. Vegetable-tanned calf has a similar lifespan if kept dry. Shell cordovan often exceeds 5 years due to its dense fibre structure. Casati Milano provides an 18-month guarantee against manufacturing defects on all straps.
