Strap for Lady-Datejust 28 White Gold - Diamond / President / Paved - Roman

The Rolex Lady-Datejust 279139RBR-0014 features a 28 mm case with a lug width of 14 mm measured internally at the spring bar insertion point. This measurement should be verified with a calliper directly on the case, not on the fitted strap.

Given the white gold case and ruby-set bezel of the Lady-Datejust 279139RBR-0014, vegetable-tanned alligator is the most coherent pairing for formal occasions. Box-calf leather suits professional daily wear, whilst vulcanised rubber works well in casual or summer settings. In all cases, the 14 mm lug width requires dedicated artisan production.

Strap replacement is carried out by removing the spring bars connecting the strap to the case lugs. A fine-tipped spring bar tool is recommended to avoid scratching the white gold case. If in doubt, a watchmaker or the Casati Milano atelier can perform the operation safely.

Yes. The 14 mm lug width is non-standard for mass-market suppliers, but Milano Straps offers handcrafted aftermarket straps specifically for this reference, available in alligator, calf leather and rubber. Each strap is made with a curved profile to fit the Lady-Datejust lug geometry and can be paired with buckles or deployant clasps matching the case metal tone.

The lifespan of a leather strap depends on hide quality, tanning method and usage conditions. A high-grade vegetable-tanned alligator strap, kept away from moisture and maintained correctly, can retain its structural and aesthetic integrity for 3 to 5 years of daily wear. Calf leather typically has a shorter service life. Milano Straps provides an 18-month production defect warranty on all straps.
