The Lady-Datejust 279383rbr-0024, seen from the bench

The Lady-Datejust 28 Rolesor Yellow Diamond is a refined expression of Rolex's iconic women's watch line, introduced in 1957. Reference 279383rbr-0024 features a 28.00 mm yellow Rolesor case—combining Oystersteel and 18-carat yellow gold—with a brilliant-cut diamond-set bezel. It houses the Rolex Caliber 2236, a manufacture movement with a Syloxi silicon balance wheel, COSC-certified chronometer, and ±2 seconds/day tolerance after internal Rolex testing. The Oyster case guarantees water resistance to 100 meters. Lug width is 14 mm, specific to this model and not interchangeable with other Datejust variants.

Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279383rbr-0024?

The Rolex Lady-Datejust 279383rbr-0024 features a lug width of 14 mm. This measurement must be verified with a calliper between the two lugs on the same side before purchasing an aftermarket strap, as it is not interchangeable with other Datejust variants such as the 26 mm, 31 mm, or 36 mm references.

What is the best strap for the Rolex Lady-Datejust 279383rbr-0024?

For the 279383rbr-0024 in yellow Rolesor with a diamond-set bezel, the most suitable straps are belly alligator in black or cognac, which enhance the contrast with the gold and complement the case texture. Vegetable-tanned calf leather offers a distinguished ageing quality, while shell cordovan develops a remarkable patina over time. All straps must have a 14 mm attachment compatible with the curvature of the Rolex Oyster lug.

How do you change the strap on a Rolex Lady-Datejust 279383rbr-0024?

To replace the strap on the Lady-Datejust 279383rbr-0024, you will need a spring bar tool with a 0.9 mm or 1.2 mm tip. Insert the tool into the lateral hole of the lug, compress the spring bar, and slide the strap free. It is advisable to work on a soft surface to avoid scratching the Rolesor case. If in doubt, consult a qualified watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279383rbr-0024?

Yes, there are numerous aftermarket straps compatible with the Rolex Lady-Datejust 279383rbr-0024, provided they feature a 14 mm attachment and, ideally, curved ends to match the Oyster lug profile. Milanostraps.it offers a curated selection of handcrafted 14 mm straps in premium leathers, directly compatible with this reference without any case modification.

How long does a leather strap last on a Rolex Lady-Datejust?

The longevity of a leather strap depends on the hide, the craftsmanship, and daily wear conditions. A vegetable-tanned alligator strap, properly cared for and kept away from prolonged exposure to water and perspiration, can last between 3 and 6 years while developing a distinguished patina. Shell cordovan tends to be more resilient over time due to its dense fibre structure. Casati Milano provides an 18-month guarantee on manufacturing defects for all bespoke straps.
