Lady-Datejust 279384rbr-0010— lug 14mm

The Rolex Lady-Datejust 279384rbr-0010 features a 28mm case with a lug width of 14mm. This measurement is specific to the 28mm Lady-Datejust variant and should be confirmed with a calliper before ordering an aftermarket strap.

For a white gold case with a diamond-set bezel, Nile alligator in vegetable-tanned leather with a polished finish is the most technically coherent choice. Box calf leather or shell cordovan offer excellent alternatives, combining character with longevity. A deployant clasp in white gold or brushed steel completes any leather pairing.

Strap replacement requires a spring bar tool or a blunt 1mm pin to release the 14mm spring bars from the lugs. Rest the case on a soft cushion and work carefully to avoid scratching the white gold surfaces. If in doubt, entrust the operation to a watchmaker or visit the Casati Milano atelier.

Yes. Any strap with a 14mm attachment and standard spring bars is technically compatible. Milano Straps offers handcrafted leather, rubber and textile straps specifically proportioned for the 28mm case of this reference.

Longevity depends on the material and daily care. A Nile alligator strap in vegetable-tanned leather, kept away from water and perfume, retains its structural and aesthetic integrity for 3–5 years with regular wear. Shell cordovan tends to exceed 5 years, developing a progressive patina over time. Casati Milano provides an 18-month warranty against manufacturing defects.
