Datejust 31 178383-0022— lug 16mm

The Rolex Datejust 31 ref. 178383-0022 features a lug width of 16mm, measured between the two lower lugs of the case at the strap attachment point (6 o'clock position). This measurement determines compatibility with any aftermarket strap.

For the two-tone yellow gold and steel configuration of the ref. 178383-0022, the most suitable materials are vegetable-tanned alligator (cognac, tobacco or bordeaux tones) and smooth polished calfskin. Shell cordovan offers a contemporary alternative with a natural patina. A deployant clasp in gold or steel is recommended to preserve the strap over time.

Replacing the strap on the Datejust 31 requires a springbar tool to remove the springbars securing the strap to the lugs. It is advisable to work on a soft cushion to avoid scratching the case. Alternatively, any qualified watchmaker can carry out the operation in a matter of minutes without risk to the watch.

Yes, numerous artisan manufacturers produce aftermarket straps with a 16mm lug width compatible with the Datejust 31. Milano Straps offers a selection of 16mm straps in leather, alligator and rubber, with steel buckles or deployant clasps, designed to fit the integrated lugs of the Datejust 31.

Longevity depends on the material and care: a quality alligator strap, properly maintained and not excessively exposed to water or perspiration, retains its structural and aesthetic integrity for 3 to 5 years with daily wear. Vegetable-tanned leather develops a patina over time that enhances its character. A deployant clasp significantly reduces mechanical stress on the strap, extending its useful life.
