The Lady-Datejust 279383rbr-0005, seen from the bench

The Rolex Lady-Datejust 28 Rolesor Yellow Diamond 279383rbr-0005 combines 28mm Rolesor yellow case—Rolex's proprietary blend of OYSTERSTEEL and 18k yellow gold—with a diamond-set dial and the caliber 2236 movement. The Chronergy escapement and Syloxi silicon oscillator deliver over 55 hours of power reserve and COSC chronometer precision of -2/+2 seconds per day. The 14mm lug width accommodates straight-end straps, essential for this model's tapered lug geometry.

Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279383rbr-0005?

The Rolex Lady-Datejust 279383rbr-0005 has a lug width of 14mm. This measurement refers to the internal distance between the two lugs at the point where the strap or bracelet attaches. It is the critical specification to confirm before purchasing any aftermarket strap compatible with this reference.

What is the best strap for the Rolex Lady-Datejust 279383rbr-0005?

For the Lady-Datejust 279383rbr-0005 in yellow Rolesor with a diamond-set dial, a polished alligator strap is the most aesthetically and materially coherent choice. The regular grain of Mississippiensis or Niloticus alligator complements the geometric pattern of the gems on the bezel. Vegetable-tanned calf leather is a practical everyday alternative, while nylon NATO and vulcanised rubber suit more casual or active settings.

How do you change the strap on the Rolex Lady-Datejust 279383rbr-0005?

Replacing the strap on the Lady-Datejust 279383rbr-0005 requires a fine-tipped or fork-style spring bar tool compatible with standard Rolex 14mm spring bars. It is advisable to work on a soft surface to avoid scratching the case and Rolesor lugs. If you are not experienced with strap changes, it is best to have the work carried out by a watchmaker or by an atelier such as Casati Milano, which performs this service by appointment.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279383rbr-0005?

Yes. The Rolex Lady-Datejust 279383rbr-0005 accepts any aftermarket strap with a straight 14mm end. Milanostraps.it offers a curated selection of handcrafted compatible straps in a range of materials — alligator, calf leather, shell cordovan, NATO and rubber — produced by the Casati Milano atelier or available for immediate online purchase.

How long does a leather strap last on a Rolex Lady-Datejust 279383rbr-0005?

The lifespan of a leather strap depends on material quality and daily use. A premium alligator or vegetable-tanned calf leather strap, with proper care — avoiding prolonged exposure to water and perspiration and rotating between multiple straps — can last between three and five years while retaining a respectable appearance. Casati Milano guarantees its straps for 18 months against manufacturing defects.
