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

The Rolex Lady-Datejust 279384rbr-0004 has a lug width of 14 mm. This dimension is specific to the 28 mm version of the Lady-Datejust family and is not shared with the Datejust 31 or 36 models, which use wider lug attachments. Always verify with a calliper that any aftermarket strap matches this measurement before fitting.

For the 279384rbr-0004 with its ruby-set bezel and white gold case, an alligator strap with curved ends is the most coherent aesthetic choice. Alternatively, vegetable-tanned calf leather or shell cordovan develop a genuine patina over time. A deployant clasp in white gold or PVD silver completes the pairing whilst maintaining chromatic consistency with the case.

Strap replacement requires a dedicated springbar tool with a 1.0–1.2 mm tip. Carefully disengage the spring bars connecting the strap to the lugs, taking care not to scratch the white gold case. For a first replacement — particularly on a gem-set piece — it is advisable to consult a watchmaker or a specialist atelier such as Casati Milano.

Yes. Compatible aftermarket straps must conform to the 14 mm lug width and feature curved ends to follow the profile of the Oyster case. Milano Straps offers a curated selection of handcrafted straps in alligator, calf leather and other materials specifically made for this attachment size.

Longevity depends on the material and frequency of wear. A quality alligator strap with vegetable tanning can last between three and seven years with standard maintenance. Calf leather typically has a shorter lifespan of two to four years. Avoiding prolonged exposure to water, perfume and perspiration significantly extends the life of any leather strap. Milano Straps provides an 18-month manufacturing guarantee on all Casati Milano straps.
