The Lady-Datejust 279175-0007, seen from the bench

The Lady-Datejust 279175-0007 is a 28mm Everose gold watch featuring Rolex's proprietary 18-karat alloy combining gold, copper, and platinum. It houses the Rolex 2236 movement, a manufacture caliber with silicon Syloxi hairspring, COSC-certified to ±2 seconds per day, and a Perpetual rotor for automatic winding. The fluted bezel captures light with rhythmic reflections, while the solid rose gold caseback maintains material coherence. Water-resistant to 100 meters via a triplock crown system. The lug width measures 14mm, specifically proportioned for the 28mm case diameter, requiring compatible 14mm straps for proper visual alignment.

Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279175-0007?

The Rolex Lady-Datejust 279175-0007 has a lug width of 14mm. This measurement is specific to the 28mm case diameter and is the key parameter when selecting a compatible replacement strap. Measure with a digital calliper between the two lugs, flush against the case.

What is the best strap for the Rolex Lady-Datejust 279175-0007 in rose gold?

For the Everose gold case of the 279175-0007, the most suitable materials are polished alligator in warm tones (cognac, burgundy), natural shell cordovan, and vegetable-tanned calf leather. A rose gold ardillon buckle ensures metallic consistency; a miniature deployant clasp is preferred for daily wear to reduce stress on the leather.

How do you change the strap on a Rolex Lady-Datejust 279175-0007?

To replace the strap, remove the spring bars from the 14mm lugs using a dedicated springbar tool. Work on a soft surface to protect the rose gold case from scratches. Alternatively, the operation can be carried out by a watchmaker or at the Casati Milano atelier during a strap fitting appointment.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279175-0007?

Yes. The standard 14mm lug width allows the use of third-party handcrafted straps built to that measurement. Milano Straps offers a selection of handmade 14mm straps with precisely calibrated ends designed to fit the Lady-Datejust lugs with no play or misalignment.

How long does a leather strap last on a Rolex Lady-Datejust 279175-0007?

Longevity depends on leather quality and frequency of use. A first-quality alligator or shell cordovan strap, with minimal care (avoid prolonged moisture and direct perfume contact), retains its aesthetic and structural properties for 2–4 years of regular use. Milano Straps provides an 18-month warranty on manufacturing defects.
