Strap for Lady-Datejust 28 Stainless Steel Domed / Oyster / Pink

The Rolex Lady-Datejust 279160-0002 has a lug width of 14 mm. This measurement, taken between the two lugs of the Oyster case in Oystersteel, is specific to this generation of 28 mm Lady-Datejust and is not interchangeable with the standard 20 mm straps used on men's Datejust references.

For a 28 mm Oystersteel case, the most suitable options are: glossy alligator belly (formal, evening wear), vegetable-tanned calf leather with a smooth finish (daily use), shell cordovan (long-lasting patina, intermediate register), and thin-profile vulcanised rubber (sport, summer). Ideal thickness is between 2.0 and 2.5 mm on the underside. A steel deployant clasp extends strap life by reducing stress on the stitching.

To replace the strap, use a fine-tipped or spring-loaded spring bar tool, inserted into the internal slot of each lug to compress the ends of the spring bar. The 14 mm spring bar releases, allowing strap removal. Work on a soft surface to protect the polished case surfaces. If you lack experience, a watchmaker or the Casati Milano atelier can perform the operation safely.

Yes. The aftermarket offers 14 mm straps compatible with the Lady-Datejust 279160-0002. Milano Straps provides a curated selection of handcrafted straps in various leathers and materials, supplied with replacement spring bars. It is essential to verify that the lug width is exactly 14 mm and that the taper thickness at the ends is compatible with the Rolex lug height (generally no more than 3.5 mm).

Longevity depends on material and usage. A vegetable-tanned calf strap worn daily typically lasts 18 to 24 months with proper care (leather conditioner, protection from water). Shell cordovan and quality alligator, owing to their denser fibre structure, can exceed three years. Using a deployant clasp significantly reduces mechanical stress on the strap's underside, extending its useful life.
