Strap for Lady-Datejust 28 Rolesor Yellow Domed / Oyster / Lavender Diamond

The Rolex Lady-Datejust 279163-0018 has a lug width of 14mm. This measurement corresponds to the internal distance between the case lugs and determines the correct width for any replacement strap. It is advisable to confirm this with a digital calliper before purchasing a new strap.

For an 18-carat yellow gold case, the most suitable straps are in alligator leather — belly cut, with its characteristic irregular grain — in cognac, burgundy or midnight blue, or in shell cordovan for a smooth, compact finish. Vegetable-tanned calf leather is a more contemporary option that develops an attractive patina over time. All straps must have a 14mm attachment width.

To replace the strap or bracelet on the Lady-Datejust 279163-0018, a precision springbar tool is required. Compress the spring bar housed within the lugs and slide out the original strap. It is recommended to work on a soft surface to protect the yellow gold case from scratches. If in doubt, consult a qualified watchmaker.

Yes. Many craftsmen and manufacturers produce aftermarket straps with a 14mm attachment compatible with the Lady-Datejust 279163-0018. It is essential that the strap ends are shaped to follow the curve of the Rolex lugs and that the spring bars are of the correct diameter. Milanostraps.it offers a curated selection of 14mm straps made to these specifications.

The lifespan of a leather strap depends on the material and how it is maintained. A high-quality alligator strap, rotated with others, can last between three and five years while retaining good structural integrity. Vegetable-tanned calf leather has a similar lifespan but develops a characterful aged patina. Prolonged contact with water, perspiration and perfume should be avoided, and the strap should be stored on a rigid support when not in use.
