Strap for Lady-Datejust 28 Everose Fluted / Jubilee / MOP

The lug width of the Rolex Lady-Datejust 279175-0018 is 14mm. This measurement is taken between the two lower lugs of the case, at the exact point where the strap attaches. It is a non-standard size: replacement straps must be specifically manufactured for a 14mm lug width.

For the Lady-Datejust 279175-0018 in 18ct Everose gold, a vegetable-tanned alligator strap is the benchmark pairing: the scale texture complements the bracelet finishing and the natural tanning process ensures longevity and an even patina development. Alternatively, polished box-calf leather or shell cordovan are refined choices for those seeking understated elegance or collector-grade character.

Replacing the strap on a Rolex Lady-Datejust requires a spring bar tool or a dedicated pin to remove the spring bars from the 14mm lugs. It is advisable to work on an anti-scratch mat and use plastic or brass-tipped tools to avoid marking the Everose gold lugs. If in doubt, consult a watchmaker or the Casati Milano atelier.

Yes. Aftermarket straps with a 14mm lug width compatible with the Lady-Datejust 279175-0018 are available in leather, vulcanised rubber, and nylon NATO configurations. Compatibility depends solely on the lug width (14mm) and the attachment curvature: some manufacturers offer curved-end options specifically designed for the Rolex Lady-Datejust family.

The lifespan of a leather strap depends on the quality of the hide, the tanning method, and daily usage. A high-quality vegetable-tanned alligator strap, properly maintained with conditioning cream and dried after exposure to moisture, can last between three and seven years with regular wear. Shell cordovan tends to last longer due to the density of its fibres. Casati Milano offers an 18-month warranty against manufacturing defects.
