Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279381rbr-0015?
The Rolex Lady-Datejust 279381rbr-0015 has a lug width of 14mm. This is the standard measurement for the 28mm variant of the Lady-Datejust family and can be confirmed using a digital calliper placed between the two lugs at the strap attachment point.
What is the best strap for the Rolex Lady-Datejust 279381rbr-0015?
For the two-tone Oystersteel and Everose gold case of the 279381rbr-0015, the most suitable materials are vegetable-tanned alligator in cognac or bordeaux tones and smooth calf leather. Shell cordovan is a distinctive choice for those seeking a natural, evolving patina. A deployant clasp is preferable to minimise wear on the leather over time.
How do you change the strap on a Rolex Lady-Datejust 28mm?
To replace the strap on a Lady-Datejust 28mm, use a fine-tipped springbar tool to release the spring bars securing the strap to the lugs. Care is essential to avoid scratching the Everose gold case: it is advisable to protect the lugs with PTFE tape during the procedure.
Are there aftermarket straps compatible with the Rolex Lady-Datejust 279381rbr-0015?
Yes. Any strap with a 14mm attachment and curved ends is technically compatible with the 28mm Lady-Datejust. It is important that the ends are shaped to follow the curvature of the Oyster case. Milano Straps offers a selection of handcrafted 14mm straps, available bespoke or ready to ship.
How long does a leather strap last on a Rolex Lady-Datejust?
Longevity depends on the material and care routine. A quality alligator strap, kept away from excessive moisture and treated periodically with a suitable leather conditioner, can last between 3 and 6 years with daily wear. Shell cordovan tends to outlast other leathers due to its dense fibre structure, developing a patina that improves with age. Milano Straps provides an 18-month guarantee against manufacturing defects.
