Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279163-0023?

The Rolex Lady-Datejust 279163-0023 features a lug width of 14mm. This measurement is specific to the 28mm case variant and requires dedicated straps with tapered ends calibrated to this width.

What is the best strap for the Rolex Lady-Datejust 279163-0023?

For the Lady-Datejust 279163-0023 in Yellow Rolesor, an alligator Louisiane strap in honey or chocolate tones complements the two-tone case beautifully. Alternatively, a vegetable-tanned calf leather strap develops a distinctive patina over time. A deployant clasp is recommended to reduce daily wear on the strap.

How do you change the strap on a Rolex Lady-Datejust 279163-0023?

The strap is replaced using a fine-tipped spring bar tool, inserted into the lug hole to release the spring bar. On a 28mm model, it is advisable to use a watch cushion and work under good lighting to avoid scratching the case. If in doubt, a qualified watchmaker can complete the operation in minutes.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279163-0023?

Yes. Milano Straps offers handcrafted aftermarket straps with a 14mm lug width, fully compatible with the Lady-Datejust 279163-0023. The ends are cut and tapered to fit the Oyster lug geometry precisely, with no modification required to the watch.

How long does a leather strap last on a Rolex Lady-Datejust 279163-0023?

The lifespan of a leather strap depends on frequency of use, exposure to perspiration and moisture, and tanning quality. A high-grade alligator or shell cordovan strap, with regular but non-sporting use, typically lasts 2 to 4 years while retaining its appearance and structure. Vegetable-tanned leather develops a patina with age, while chrome-tanned leather tends to remain more uniform over time.
