Strap for Lady-Datejust 28 Stainless Steel Fluted / Grey - Roman / Oyster

The Rolex Lady-Datejust 279174-0014 has a lug width of 14mm. This is a non-standard size, narrower than the typical 20mm found on men's Datejust models. To verify the measurement on your own piece, use a digital calliper to measure the gap between the lugs at the strap attachment point.

Given the Oystersteel and white gold case of the 279174-0014, a polished alligator strap — Porosus or Mississippiensis — is the most aesthetically consistent choice. Vegetable-tanned calf leather offers a more casual everyday option that develops a personal patina over time. For sporting use, vulcanised rubber provides durability and comfort.

The strap on the Lady-Datejust is removed using a springbar tool. Insert the tool into the small lug hole, compress the spring, and slide the strap free. The operation is fully reversible and does not require a watchmaker, though care should be taken to avoid scratching the white gold lugs.

Yes. Any strap with a 14mm lug width and standard springbars is technically compatible with the Lady-Datejust 279174-0014. Milanostraps.it offers a curated selection of handcrafted 14mm straps, available bespoke or ready to order online, in materials suited to the white gold and steel case of this reference.

The lifespan of a leather strap depends on the material, frequency of use, and conditions. A high-quality alligator strap used daily and kept away from moisture typically lasts 2 to 4 years. Vegetable-tanned calf develops a patina over a similar period. Casati Milano straps carry an 18-month warranty against manufacturing defects.
