Strap for Lady-Datejust 28 Everose Fluted / President / Olive Green Diamond

The Rolex Lady-Datejust ref. 279175-0009 has a lug width of 14 mm. This measurement is taken with a calliper between the two lugs of the case, at the strap attachment point. It is specific to the 28 mm Lady-Datejust models of this generation and should not be confused with the 13 mm found on certain vintage references or the 15 mm of other variants.

For an Everose gold case measuring 28 mm, an alligator strap in bordeaux or cognac provides the most coherent chromatic and formal pairing. Shell cordovan in a neutral tone offers a more contemporary reading. For everyday wear, vegetable-tanned calf leather ensures comfort and characterful ageing. The buckle or deployant clasp should match the Everose gold tone of the case.

Strap replacement requires a spring bar tool. Standard spring bars with a 1.5 mm diameter are compatible with the 14 mm lugs of the Lady-Datejust. It is advisable to work on a soft surface to avoid scratching the Everose gold case. If in doubt, the operation can be entrusted to a watchmaker or the Casati Milano atelier.

Yes. Aftermarket straps with a 14 mm lug width are compatible with the ref. 279175-0009, provided the ends are correctly shaped to fit the curvature of the 28 mm Rolex lugs. Milano Straps offers a dedicated selection of handcrafted 14 mm straps, available as bespoke orders or ready-to-ship online, in various leathers and finishes.

The lifespan of a leather strap depends on the quality of the hide, daily care, and frequency of use. A high-quality alligator or shell cordovan strap, properly maintained — avoiding prolonged contact with water and perspiration, and occasionally applying a neutral conditioner — can last between 3 and 7 years while retaining a distinguished appearance. Vegetable-tanned calf leather straps tend to have a slightly shorter lifespan but develop a patina that is highly prized among enthusiasts.
