Datejust 31 178383-0007— lug 16mm

The lug width of the Rolex Datejust 31 178383-0007 is 16 mm. This measurement refers to the internal distance between the two case lugs at the strap attachment point and should be verified with a calliper before purchasing any replacement strap.

For the Datejust 31 178383-0007 in yellow gold Rolesor, vegetable-tanned alligator straps in honey, tobacco or burgundy tones complement the warm hues of the gold and the formal character of the watch. Box-calf leather is ideal for daily professional use, while vulcanised rubber is the most functional choice for sportier contexts.

To remove the original strap, a spring bar tool acting on the 16 mm spring bars lodged between the case lugs is required. Compress the spring bar, release one lug at a time, then insert the new strap by reversing the operation. It is advisable to work on a soft surface to avoid scratching the stainless steel and yellow gold case.

Yes. Any strap with a 16 mm attachment and standard spring bars is compatible with the Datejust 31 178383-0007. Milanostraps.it offers a curated selection of handcrafted leather, NATO and rubber straps catalogued specifically for 16 mm lug width, with customisation options available through the Casati Milano atelier.

A quality leather strap — alligator or vegetable-tanned calf — fitted to a Datejust 31 with regular use has an average lifespan of 18 to 36 months. Longevity depends on exposure to perspiration, humidity and cosmetic products. Periodic conditioning with a suitable leather cream and rotation with a second strap can significantly extend its useful life.
