The Lady-Datejust 279175-0023, seen from the bench

The Rolex Lady-Datejust 28 ref. 279175-0023 features an 18-karat Everose gold case with a 28mm diameter and houses the Rolex calibre 2236 movement, a COSC-certified chronometer with approximately 55 hours power reserve. The Syloxi balance wheel in silicon ensures superior frequency stability, while the Twinlock crown guarantees water resistance. The 14mm lug width is a specific design parameter for the Lady segment, requiring proportioned straps to preserve dial harmony and proper fit without exceeding 0.3mm tolerance variation.

Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279175-0023?

The Rolex Lady-Datejust 279175-0023 has a lug width of 14mm. This measurement is taken with a digital calliper placed inside the lug holes and is the key parameter for selecting a compatible strap. All 14mm straps on milanostraps.it are manufactured with end-pieces calibrated to this tolerance.

What is the best strap for the Rolex Lady-Datejust 279175-0023 in Everose gold?

On an 18kt Everose gold case, the most suitable materials are hornback alligator leather, vegetable-tanned calf leather, and shell cordovan. Alligator enhances the texture of the case, vegetable-tanned calf develops a personalised patina over time, and shell cordovan offers compactness and moisture resistance. A butterfly deployant clasp in Everose gold completes the pairing with chromatic continuity.

How do you change the strap on the Rolex Lady-Datejust 279175-0023?

To replace the strap on the Lady-Datejust 279175-0023, the spring bars connecting the strap to the case lugs must be removed. A forked spring bar tool is used to lever at the lug notch, taking care not to scratch the Everose gold. Standard spring bars are 1.5mm in diameter. It is advisable to rest the watch on a soft cloth and, if in doubt, entrust the operation to a watchmaker or the Casati Milano atelier.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279175-0023?

Yes. The Lady-Datejust 279175-0023 accepts any strap with a 14mm attachment and standard 1.5mm spring bars. milanostraps.it offers a selection of handcrafted straps with curved end-pieces calibrated to Rolex Lady lugs, available in various materials — leather, rubber, nylon — with finishes compatible with the 18kt Everose gold case.

How long does a leather strap last on the Rolex Lady-Datejust 279175-0023?

The lifespan of a leather strap depends on the material, maintenance, and daily use. A vegetable-tanned calf strap, with regular care (nourishing cream every 2–3 months, kept away from water), can last between 2 and 4 years. Shell cordovan and alligator, due to their structural density, generally last longer. milanostraps.it guarantees its straps for 18 months against manufacturing defects.
