Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279174-0009?

The Rolex Lady-Datejust 279174-0009 features a 28 mm case with a lug width of 14 mm. This is a non-standard size compared to larger sports models: always verify the measurement with a digital calliper before purchasing any aftermarket strap.

What is the best strap for the Rolex Lady-Datejust 279174-0009?

Given the mother-of-pearl dial and white gold bezel, the most suitable materials are alligator leather in pearl grey or ivory tones, shell cordovan in navy or burgundy, and vegetable-tanned calf leather for a more everyday aesthetic. During summer months, a vulcanised rubber strap in white or light grey offers comfort and water resistance.

How do you change the strap on a Rolex Lady-Datejust 28mm?

To remove the original bracelet or strap, you will need a spring bar tool or replacement 14 mm spring bars. Given the reduced scale of the lugs and the white gold construction, it is strongly advisable to have the operation carried out by a qualified watchmaker to avoid scratching the case.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279174-0009?

Yes. Any 14 mm strap with straight or slightly curved ends is compatible with this reference. Milano Straps offers a curated selection of handcrafted 14 mm straps with ends shaped to match the Oyster case geometry, available in various materials and colours.

How long does a leather strap last on a Rolex Lady-Datejust 28mm?

A quality leather strap — whether vegetable-tanned calf or alligator — typically lasts between 2 and 4 years with daily wear. Longevity depends on exposure to perspiration, water and UV light. Using a deployant clasp significantly reduces daily mechanical stress on the strap attachment, extending its service life.
