The Lady-Datejust 279163-0008, seen from the bench

The Rolex Lady-Datejust 28 Rolesor Yellow 279163-0008 combines a 28mm yellow Rolesor case—stainless steel and 18K yellow gold—with the iconic design introduced in 1957. It features a fluted bezel, date window at 3 o'clock, and Twinlock crown, powered by the Rolex 2236 automatic chronometer movement with approximately 55 hours power reserve. The 14mm lug width requires a specifically tailored strap, as generic aftermarket options are unavailable at this size.

Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279163-0008?

The Rolex Lady-Datejust 279163-0008 features a 28mm case with a lug width of 14mm. This measurement is specific to the 28mm Lady-Datejust format and falls outside the most common aftermarket strap widths. To verify it independently, use a digital calliper placed on the inside of the lugs at the point where the strap sits.

What is the best strap for the Rolex Lady-Datejust 279163-0008?

For the Lady-Datejust 279163-0008 in steel and yellow gold, the most suitable straps are alligator with belly grain for formal occasions, vegetable-tanned calf leather for daily wear with natural patina development, or shell cordovan for a compact, luminous surface. A deployant clasp in polished steel or yellow gold is the most coherent closure choice for the Rolesor aesthetic of this reference.

How do you change the strap on a Rolex Lady-Datejust 279163-0008?

Replacing the strap on the Lady-Datejust 279163-0008 requires a double-ended spring bar tool to remove the spring bars housed within the lugs. It is essential to use a tool with protected tips to avoid scratching the Rolesor case. Place the watch on a soft cushion and work under adequate lighting. If in doubt, a watchmaker or the Casati Milano atelier can carry out the operation without risk.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279163-0008?

Yes, aftermarket straps specifically made for the 14mm lug width of the Lady-Datejust 279163-0008 do exist. Milanostraps.it offers a curated selection of 14mm straps in various materials and finishes, crafted to fit the lugs of this model precisely. Always verify that the attachment width is exactly 14mm and that the strap ends are shaped to follow the curvature of the Rolex case.

How long does a leather strap last on a Rolex Lady-Datejust 279163-0008?

The lifespan of a leather strap depends on the material, frequency of use and care. A quality alligator strap worn daily maintains structural and aesthetic integrity for 2–4 years. Vegetable-tanned calf has a similar lifespan with the added benefit of developing patina over time. Shell cordovan is generally more durable and longer-lasting. Avoiding prolonged contact with water, perspiration and perfumes significantly extends the strap's life. Casati Milano offers an 18-month guarantee against manufacturing defects.
