Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279173-0013?

The Rolex Lady-Datejust 279173-0013, fitted with a 28mm Rolesor case, has a lug width of 14mm. This measurement should be taken with a calliper at the inner side of the lugs, flush against the case, to obtain the correct dimension before purchasing an aftermarket strap.

What is the best strap for the Rolex Lady-Datejust 279173-0013?

For the Lady-Datejust 279173-0013 with its mother-of-pearl dial and yellow gold bezel, the most suitable straps are vegetable-tanned alligator belly — in cognac, bordeaux or ivory tones — or shell cordovan for a naturally specular finish. The lug width is 14mm. A deployant clasp in yellow gold or gold-toned steel completes the pairing in a manner consistent with the case metals.

How do you change the strap on a Rolex Lady-Datejust 279173-0013?

To replace the strap on the Lady-Datejust 279173-0013, a springbar tool is required to release the spring bars connecting the strap to the 14mm lugs. Insert the forked tip into the lug hole, compress the spring bar and slide the strap free. Care should be taken to avoid scratching the yellow gold or Oystersteel lug surfaces during the operation.

Is there an aftermarket strap compatible with the Rolex Lady-Datejust 279173-0013?
