Strap for Lady-Datejust 28 Yellow Gold Diamond / President / Lavender Diamond

The lug width of the Rolex Lady-Datejust 279138RBR-0027 is 14mm. This measurement is specific to the 28mm case size and is not interchangeable with the 31mm or 36mm variants of the Datejust family. Always verify this dimension before purchasing an aftermarket strap.

For the Lady-Datejust 279138RBR-0027 in 18ct yellow gold with a diamond pavé dial, an alligator strap with belly grain is the most coherent choice given the watch's formal register. Alternatively, a vegetable-tanned box-calf leather strap offers refined daily elegance with a patina that improves over time. A yellow gold or gold PVD buckle or deployant clasp ensures metallic continuity with the case.

To replace the strap on the Lady-Datejust 279138RBR-0027, use a fine-tipped spring bar tool to release the spring bars securing the strap to the 14mm lugs. Take care not to scratch the 18ct yellow gold case. If you are unfamiliar with the procedure, it is advisable to consult a watchmaker or visit the Casati Milano atelier.
