The Lady-Datejust 279173-0019, seen from the bench

The Lady-Datejust 28 Rolesor Yellow ref. 279173-0019 is a timepiece designed from its origin for the female wrist. The 28mm case combines Oystersteel and 18K yellow gold in Rolex's patented Rolesor configuration, with yellow gold on the lugs, bezel, and crown for structural balance. Inside, the Rolex caliber 2236 movement features a Syloxi silicon oscillator for temperature and magnetic resistance, COSC chronometer certified with approximately 55 hours of power reserve. The date window at 3 o'clock operates via Quickset mechanism. The 14mm lug width defines a dedicated strap ecosystem distinct from standard sizes, requiring specialized manufacturers for compatibility.

Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279173-0019?

The Rolex Lady-Datejust 279173-0019 has a lug width of 14mm. This is a size specific to the 28mm Lady-Datejust models and requires straps manufactured to this exact width, which are not interchangeable with the more common 16mm or 18mm sizes.

What is the best strap for the Rolex Lady-Datejust 279173-0019?

For the Lady-Datejust 279173-0019 in Yellow Rolesor, an alligator strap with vegetable tanning is the most aesthetically coherent choice. The belly grain in bordeaux or deep cognac enhances the yellow gold without overwhelming the 28mm case. Smooth calf leather and shell cordovan are valid alternatives for a more contemporary profile.

How do I change the strap on a Rolex Lady-Datejust 279173-0019?

Strap replacement requires a double-pronged spring bar tool. Insert the tool into the gap between the lug and the strap end, compress the spring bar and slide out the bar on both sides. It is recommended to work on a soft surface to protect the Rolesor case from accidental scratches.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279173-0019?

Yes. Several artisan manufacturers produce 14mm aftermarket straps compatible with the Lady-Datejust 279173-0019. Milano Straps offers a selection of leather, rubber and other materials specifically sized for the 14mm lug, with a bespoke option available at the Casati Milano atelier.

How long does a leather strap last on a Rolex Lady-Datejust 279173-0019?

Longevity depends on the material and frequency of wear. A quality vegetable-tanned alligator strap, worn regularly, maintains its structural and aesthetic integrity for 3 to 5 years with minimal care. Calf leather typically lasts 2 to 3 years. Perspiration and water contact are the primary causes of wear; leather straps should not be worn during sport or in humid environments.
