Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279175-0029?

The lug width of the Rolex Lady-Datejust 279175-0029 is 14 mm. This measurement is specific to the 28 mm case and differs from other Datejust variants such as the 31 mm (16 mm lugs) or the 36 mm (20 mm lugs). Always verify the lug width using a digital calliper placed inside the lugs before purchasing any aftermarket strap.

What is the best strap for the Rolex Lady-Datejust 279175-0029?

For the Lady-Datejust 279175-0029 in 18kt Everose gold, a vegetable-tanned alligator strap offers the most coherent pairing: the grain texture complements the fluted bezel, and the natural patina develops harmoniously over time. For more active wear, a vulcanised FKM rubber strap is a practical alternative. All straps must feature a 14 mm lug width.

How do you change the strap on a Rolex Lady-Datejust 279175-0029?

The strap on the Rolex Lady-Datejust 279175-0029 is removed using a fine-tipped springbar tool, applying gentle pressure to release the springbars within the lugs. It is advisable to work on a soft surface to protect the Everose gold case from scratches. If in doubt, entrust the operation to a qualified watchmaker or to the Casati Milano atelier.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279175-0029?

Yes, high-quality aftermarket straps are available for the Rolex Lady-Datejust 279175-0029, provided they feature a 14 mm lug width and shaped ends to match the curvature of Rolex lugs. Milanostraps.it offers a curated selection of handcrafted 14 mm straps in various materials, made to order by the Casati Milano atelier.

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

A quality leather strap on a Rolex Lady-Datejust typically lasts between 2 and 4 years under regular use, depending on the material, frequency of wear and level of care. Vegetable-tanned alligator straps tend to have the longest lifespan due to their dense fibre structure. Prolonged exposure to water and cosmetics should be avoided.
