Lady-Datejust 279171-0022— lug 14mm

The Rolex Lady-Datejust 279171-0022 features a 28mm case with a lug width of 14mm, measured internally between the two lugs perpendicular to the strap axis. This measurement should be taken with a digital calliper to ensure compatibility with any aftermarket strap.

Given the Everose and Oystersteel bimaterial case, a vegetable-tanned alligator strap with Hornback or Mississippiensis grain is the most aesthetically coherent choice. Box-calf leather offers a more formal look, whilst shell cordovan develops a distinctive patina over time. The required lug width is 14mm.

The strap is removed using a spring bar tool to release the spring bars connecting the strap to the case lugs. Whilst this can be done at home with the proper tools, it is advisable to entrust the operation to a watchmaker or specialist atelier to avoid scratching the Everose gold lugs. Standard 1.5mm diameter spring bars are compatible with this case.

Yes. Several artisan manufacturers produce straps with a 14mm attachment compatible with the Lady-Datejust 279171-0022. Milano Straps offers a curated selection of 14mm straps in leather, rubber, and textile specifically sized for this case. It is essential to ensure that the aftermarket strap does not damage the Everose gold lugs: straps with coated or high-quality stainless steel spring bars are recommended.

Longevity depends on the leather type and usage. A quality vegetable-tanned alligator strap, maintained regularly (conditioning cream every 3–4 months, avoiding prolonged exposure to water and perspiration), can last between 3 and 7 years whilst retaining good structural integrity. Shell cordovan generally has a longer service life due to its dense fibrous structure. Avoiding use during physical activity significantly extends the strap's lifespan.
