Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279459RBR?

The Rolex Lady-Datejust 279459RBR has a lug width of 14mm. This measurement is specific to the 28mm case and should always be verified with a digital calliper positioned between the two lugs before purchasing any replacement strap.

What is the best strap for the Rolex Lady-Datejust 279459RBR?

For an 18-carat white gold case with a ruby-set bezel, an alligator strap in vegetable-tanned leather offers the most coherent aesthetic pairing: the natural grain and developing patina complement the Fluted bezel without overpowering it. Shell cordovan is the alternative for a more austere look. For sporting use, a vulcanised rubber strap with a deployant clasp maintains waterproofness without compromising the Oyster character of the watch.

How do you change the strap on a Rolex Lady-Datejust 279459RBR?

To replace the strap or bracelet on the Lady-Datejust 279459RBR, the spring bars securing the strap to the 14mm lugs must be removed. Use a fine-tipped springbar tool, levering carefully on the inside of each lug to avoid scratching the white gold case. The operation is fully reversible and does not require opening the caseback.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279459RBR?

Yes. Any aftermarket strap with a 14mm lug width and standard spring bars is compatible with the Lady-Datejust 279459RBR. Casati Milano produces handcrafted straps calibrated precisely to this width, available in alligator, calfskin, shell cordovan and rubber, with steel or white gold buckles available on request.

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

The lifespan of a leather strap depends on the quality of the hide, the tanning method and daily wear conditions. A vegetable-tanned alligator strap of artisanal quality, kept away from excessive moisture and perspiration, typically lasts between three and five years before replacement is needed. Casati Milano provides an 18-month warranty against manufacturing defects on all handcrafted straps.
