Strap for Lady-Datejust 28 Stainless Steel Domed / Jubilee / Dark Grey Roman

The Rolex Lady-Datejust reference 279160-0011 features a 28mm Oyster case with 14mm lug width. This measurement is specific to the 28mm Lady-Datejust and is not interchangeable with 18mm or 20mm straps. Any replacement strap must be designed precisely for a 14mm lug width to ensure correct fitment and aesthetic alignment.

For the Lady-Datejust 279160-0011 in Oystersteel with a smooth bezel, the most suitable options are Louisiana or hornback alligator leather for its three-dimensional grain, shell cordovan for its compact, almost metallic patina, and vegetable-tanned calf leather for its noble ageing characteristics. The choice depends on the intended context and colour palette. A deployant clasp in steel provides visual symmetry with the case and reduces mechanical stress on the leather at the fold.

Replacing the strap on the Lady-Datejust 279160-0011 requires a springbar tool — a double-tipped instrument designed to compress the spring bars that secure the strap to the case lugs. The operation should be carried out carefully to avoid scratching the Oystersteel case. It is advisable to work on a soft surface and, if in doubt, to entrust the task to a watchmaker or the Casati Milano atelier.

Yes, artisanal aftermarket straps compatible with the Lady-Datejust 279160-0011 are available, provided they are made with a 14mm lug width. Milano Straps offers a dedicated selection of 14mm straps in various materials — alligator, calf, shell cordovan, NATO and rubber — crafted by hand and available either ready to ship online or as bespoke commissions through the Casati Milano atelier.

The lifespan of a leather strap on the Lady-Datejust 279160-0011 depends on the material and conditions of use. A vegetable-tanned calf or shell cordovan strap, with routine care — avoiding prolonged contact with water and perspiration and applying leather conditioner periodically — can last between two and five years whilst developing an attractive patina. Alligator leather, being denser and more resilient, tends to offer greater longevity. Milano Straps provides an 18-month guarantee against manufacturing defects.
