Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279381rbr-0012?
The Rolex Lady-Datejust 279381rbr-0012 has a lug width of 14mm. This measurement is taken with a digital calliper placed internally between the two lugs at the strap entry point. It is a dimension specific to the Lady-Datejust 28mm family and determines compatibility with aftermarket straps.
What is the best strap for the Rolex Lady-Datejust 279381rbr-0012?
For the Lady-Datejust 279381rbr-0012 in Everose Rolesor with a diamond-set bezel, the most suitable straps are alligator with square scale grain in burgundy, dusty rose or midnight blue, or shell cordovan in burgundy. Both complement the warm tone of the Everose gold and pair well with the diamond bezel. For intensive daily wear, a vegetable-tanned calf leather in cognac or tobacco develops a harmonious patina over time.
How do you change the strap on a Rolex Lady-Datejust 279381rbr-0012?
To replace the strap on the Lady-Datejust 279381rbr-0012, a spring bar tool is required. The 14mm spring bars are compressed laterally using the tool tip to release the strap from the case lugs. Care must be taken to avoid scratching the Everose Rolesor case. If in doubt, it is advisable to entrust the operation to a watchmaker or to the Casati Milano atelier.
