Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 279384rbr-0001?

The lug width of the Rolex Lady-Datejust 279384rbr-0001 is 14 mm. This measurement should be taken with a digital calliper at the narrowest point between the lugs, closest to the case. It is important not to confuse this figure with the strap width at the buckle end, which may differ depending on the strap model chosen.

What is the best strap for the Rolex Lady-Datejust 279384rbr-0001?

For the Rolex Lady-Datejust 279384rbr-0001 in white gold with a diamond-set bezel, a lisse alligator strap with tapered ends is the most coherent aesthetic choice. Ivory, powder or dark grey tones complement the case without competing with the precious details. Alternatively, vegetable-tanned calf leather or shell cordovan offer an evolving patina suited to those who favour a more personal aesthetic.

How do you change the strap on the Rolex Lady-Datejust 279384rbr-0001?

The strap on the Rolex Lady-Datejust 279384rbr-0001 is secured by two 1.5 mm spring bars inserted into the case lugs. To replace it, use a fine-tipped spring bar tool — preferably with a forked tip — inserted into the inner groove of the lug to compress the spring bar and release the strap. It is advisable to work on a soft surface to avoid scratching the white gold case.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 279384rbr-0001?

Yes. The Rolex Lady-Datejust 279384rbr-0001 accepts aftermarket straps with a 14 mm attachment and preformed or tapered ends designed to follow the curvature of the Oyster lugs. It is essential to verify that the end piece thickness does not exceed 2.5 mm to ensure correct spring bar fitment. Milano Straps offers a selection of handcrafted 14mm straps specifically compatible with this reference.

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

The lifespan of a leather strap on a Rolex Lady-Datejust depends on the material, care and daily use. A quality alligator strap, kept away from moisture and perfume, will retain its structural integrity for 3 to 5 years with regular use. Vegetable-tanned calf leather tends to develop patina but is more sensitive to water. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
