Datejust 31 178248-0048— lug 16mm

The lug width of the Rolex Datejust 31 178248-0048 is 16 millimetres. This measurement represents the distance between the case lugs where the strap attaches, measured between the centres of the horizontal pins. Verifying this compatibility is essential before purchasing an aftermarket strap.

For the yellow gold 18 carat Datejust 31, an alligator strap represents the formal choice par excellence: the natural scales of the leather provide unrivalled elegance. Alternatively, vegetable-tanned calf offers superior versatility through its natural patina development over time, maintaining aesthetic coherence with the yellow gold case.

Strap replacement requires specific tools: a spring bar tool to remove the elastic pins from the case lugs. Position the watch on a soft surface, gently lift one spring bar at a time, extract the pin, remove the worn strap, and insert the new one by aligning the attachment holes with precision. Alternatively, authorised repairers and bespoke ateliers such as Casati Milano provide this service professionally.

Yes, any strap with a 16mm lug width is compatible with the Datejust 31 178248-0048.
