Datejust 31 178288-0028— lug 16mm

The lug width of the Rolex Datejust 31 178288-0028 is 16mm. This measurement refers to the internal distance between the lugs — the precise point where the strap is inserted. To verify this on your own piece, use a digital calliper positioned internally between the lugs.

For a yellow gold 18-carat case such as the Datejust 31 178288-0028, the most suitable materials are glossy alligator in warm tones (tobacco, cognac, burgundy) and shell cordovan, which develops a distinguished patina over time. Vegetable-tanned calf leather is the most versatile option for everyday wear. Warm tones are recommended to maintain chromatic coherence with the metal.

The strap on the Datejust 31 178288-0028 is removed using a spring bar tool, which compresses the spring bars housed between the lugs. Care must be taken not to scratch the yellow gold case. If you are not experienced with this procedure, it is advisable to entrust the operation to a watchmaker or to the Casati Milano atelier.
