Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279381rbr-0017?
The Rolex Lady-Datejust 279381rbr-0017 features a 28 mm case with a lug width of 14 mm. This specification is particular to the current generation of the Lady-Datejust 28 and requires straps cut precisely to 14 mm to ensure a correct fit without lateral stress on the strap ends.
What is the best strap for the Rolex Lady-Datejust 279381rbr-0017?
For the Lady-Datejust 279381rbr-0017 in Rolesor Everose, straps in vegetable-tanned alligator leather or shell cordovan are the most aesthetically coherent choices for this dress-oriented watch. Bordeaux or cognac alligator enhances the warm tones of Everose gold, whilst box-calf leather offers a more understated option for daily wear. For aquatic or sportive contexts, vulcanised rubber is the only technically sound alternative.
How do you change the strap on a Rolex Lady-Datejust 279381rbr-0017?
To replace the strap or bracelet on the Lady-Datejust 279381rbr-0017, you will need a fine-tipped spring bar tool with a head width of 0.7–0.9 mm, suitable for the narrow 14 mm lug spacing. Insert the tool into the side hole of the lug, compress the spring bar and slide the strap free. It is advisable to work on an anti-scratch mat under good lighting to avoid marking the Oystersteel case.
Are there aftermarket straps compatible with the Rolex Lady-Datejust 279381rbr-0017?
Yes. Any strap with a 14 mm attachment width is technically compatible with the Lady-Datejust 279381rbr-0017, provided the spring bar length is appropriate (typically 16–17 mm for this model) and the leather or material thickness does not exceed 3–3.5 mm to avoid stress on the case back. Milano Straps offers a dedicated selection of handcrafted 14 mm straps, available as bespoke commissions or ready to purchase online.
How long does a leather strap last on a Rolex Lady-Datejust 279381rbr-0017?
The lifespan of a leather strap depends on leather quality, care and frequency of use. A superior vegetable-tanned alligator strap, rotated with other straps and kept away from excessive moisture and perspiration, can last between three and seven years whilst developing a distinguished patina. Calf leather tends to degrade more rapidly under mechanical stress and humidity. A deployant clasp significantly reduces the number of opening and closing cycles, considerably extending the strap's service life.
