Strap for Lady-Datejust 28 Rolesor Rose Fluted / Oyster / Chocolate Diamond

The Rolex Lady-Datejust 279171-0004 has a lug width of 14mm. This measurement is specific to the 28mm Lady-Datejust family and differs from the 36mm or 41mm Datejust references. To verify it, use a digital calliper positioned between the two lugs parallel to the case.

For the Lady-Datejust 279171-0004 in Rolesor Everose, the most suitable materials are polished alligator in bordeaux or midnight blue — which complements the warmth of the rose gold — and vegetable-tanned calf leather for everyday wear with natural patina development. Shell cordovan is a characterful option for those seeking a compact, naturally lustrous surface. The strap attachment must be exactly 14mm wide.

To replace the strap on the Lady-Datejust 279171-0004, use a fine-tipped spring bar tool to release the spring bars between the lugs. Given the delicacy of the 18-carat rose gold lugs, it is strongly advisable to protect the case with adhesive tape during the operation or to entrust the task to a qualified watchmaker or the Casati Milano atelier.

Yes. Any strap with a 14mm attachment and standard spring bars is compatible with the Lady-Datejust 279171-0004. Milano Straps offers a specific selection of handcrafted 14mm straps in alligator, calf leather and shell cordovan, made with shaped ends designed to fit correctly within the Rolex lug geometry without play or tension.

Longevity depends on the material and conditions of use. A quality vegetable-tanned calf leather strap under moderate daily wear typically lasts 2–4 years before showing significant signs of deterioration. Alligator, when properly maintained, can exceed 5 years. Prolonged contact with water and perspiration should be avoided, and occasional application of a leather conditioner is recommended for vegetable-tanned leathers.
