Strap for Lady-Datejust 28 Rolesor Yellow Diamond / Oyster / Silver Diamond

The Rolex Lady-Datejust reference 279383rbr-0008 features a 28mm case with a lug width of 14mm. This measurement — best taken with a digital calliper positioned inside the lugs — is essential for selecting a compatible strap that fits precisely and sits correctly on the case.

For a Rolesor case in yellow gold and steel with a ruby-set bezel, a square-scale alligator strap in cognac or bordeaux is the most coherent aesthetic choice, complementing both the metal tones and the colour of the stones. Alternatively, vegetable-tanned calfskin develops a natural patina suited to daily wear, while shell cordovan offers a compact grain and excellent longevity. The correct lug width is 14mm.

Removing the original bracelet or strap requires a springbar tool to release the spring bars housed within the lugs without scratching the case. The 14mm lugs of the Lady-Datejust 279383rbr-0008 accept standard spring bars calibrated to the lug width. Work on a soft surface and, if inexperienced, entrust the operation to a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 14mm attachment is technically compatible with the Lady-Datejust 279383rbr-0008. Milano Straps offers a curated selection of handcrafted 14mm straps in leather, rubber and NATO nylon. Bespoke pieces by Casati Milano are built to millimetric specifications, tailored precisely to the geometry of the 28mm case.

The lifespan of a leather strap depends on material quality, tanning method and daily use. A high-grade alligator or shell cordovan strap, vegetable-tanned, can last between 3 and 7 years with proper care — periodic cleaning with appropriate products, rotation between multiple straps, and avoiding prolonged exposure to water and perspiration. Casati Milano straps carry an 18-month warranty against manufacturing defects.
