Strap for Lady-Datejust 28 Rolesor Rose Diamond / Jubilee / Sundust Diamond

The Rolex Lady-Datejust 279381rbr-0019 features a 28mm Oyster case with 14mm lug width. This specification is particular to the Lady-Datejust 28 and is not interchangeable with straps designed for larger Rolex models. To measure accurately, use a digital calliper positioned between the two lugs at their narrowest point, closest to the case.

For the Lady-Datejust 279381rbr-0019 in Everose Rolesor, an alligator strap in vegetable-tanned leather — in burgundy or tobacco brown — complements the warm tone of Everose gold. Polished black box calf leather is the most versatile formal choice. For daily or active wear, a vulcanised rubber strap with a deployant clasp provides secure fit and water resistance without compromising aesthetics.

To replace the strap on the Lady-Datejust 279381rbr-0019, remove the spring bars from the 14mm lugs using a flat-head screwdriver or a dedicated springbar tool. Work on a soft surface to protect the dial and the polished case surfaces. If uncertain, entrust the operation to a qualified watchmaker or a specialist atelier such as Casati Milano.

Yes. The Lady-Datejust 279381rbr-0019 accepts any handcrafted strap made to a 14mm lug width with standard 1.5mm spring bars. Milanostraps.it offers a curated range of 14mm straps in alligator, calf leather and rubber, all crafted to fit the Oyster case precisely. A well-made aftermarket strap is fully comparable to the original in terms of fit and comfort.

Longevity depends on leather quality, tanning method and frequency of use. A vegetable-tanned alligator strap, properly cared for and rotated with at least one other strap, can maintain structural and aesthetic integrity for 3 to 5 years. Prolonged exposure to water, perspiration and perfume accelerates deterioration. It is advisable to remove the strap before physical activity. Casati Milano's craftsmanship guarantee covers manufacturing defects for 18 months.
