The Lady-Datejust 279175-0001, seen from the bench

The Lady-Datejust 279175-0001 is a 28mm timepiece in Everose gold, Rolex's proprietary 18-karat rose gold alloy designed to resist oxidation and maintain its warm, amber-toned color. Powered by the caliber 2236, a manufacture movement developed specifically for Lady models, it features a Syloxi silicon oscillator, Chronergy hairspring, and approximately 55 hours of power reserve with COSC chronometer-certified parameters. The Oyster case combines satin and polished surfaces, with the date window at 3 o'clock fitted with a Cyclops lens; the lug width is 14mm, requiring precision-fitted aftermarket straps to avoid mounting issues or damage to the Everose lugs.

Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279175-0001?

The Rolex Lady-Datejust 279175-0001 has a lug width of 14mm. This measurement refers to the internal distance between the case lugs at the point where the strap is inserted, best taken with a digital calliper. It is specific to the 28mm Lady-Datejust case and is not interchangeable with the 20mm straps used on larger Datejust references.

What is the best strap for the Rolex Lady-Datejust 279175-0001 in rose gold?

For the 279175-0001 in Everose gold, the most suitable materials are alligator in cognac or bordeaux tones, shell cordovan in burgundy, and vegetable-tanned Box calf leather. All of these enhance the warm reflections of Everose gold. A deployante or pin buckle in rose gold at 14mm completes the pairing with full metal coherence.

How do you change the strap on a Rolex Lady-Datejust 279175-0001?

Strap replacement requires a suitable spring bar tool matched to the type of spring bars fitted — press-fit or threaded. Work on a soft cushion to protect the Everose gold case from scratches. Given the delicacy of the 18-carat rose gold lugs, it is advisable for first-time users to consult a watchmaker or to use an aftermarket strap supplied with correctly calibrated 14mm spring bars.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279175-0001?

Yes. Compatible aftermarket straps must have 14mm ends with spring bars suited to the Oyster lugs of the Lady-Datejust 28mm case. Milanostraps.it offers a selection of handcrafted 14mm straps in leather, rubber and technical materials, all made to the exact specification of this model. Casati Milano also provides bespoke commissions with direct material selection at the atelier.

How long does a leather strap last on a Rolex Lady-Datejust 279175-0001?

Longevity depends on material and usage. A quality alligator strap, with periodic conditioning, retains its structural and aesthetic integrity for 3 to 5 years with daily wear. Shell cordovan tends to last longer, developing a distinctive patina over time. Vegetable-tanned calf averages 2 to 3 years. Prolonged exposure to water, perspiration and perfume shortens lifespan considerably; rotating between two or more straps is advisable for a rose gold Lady-Datejust.
