Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279171-0001?
The Rolex Lady-Datejust 279171-0001 has a lug width of 14mm. This measurement should be taken with a digital calliper at the point of contact between the lug and the strap, and must match 14mm precisely to ensure a flush, gap-free fit. All straps listed under the 14mm section on milanostraps.it are designed specifically for this lug width.
What is the best strap for the Rolex Lady-Datejust 279171-0001?
For the Rolesor Everose case of the 279171-0001, the most appropriate straps — both technically and aesthetically — are French-tannery alligator in a gloss finish for formal wear, and vegetable-tanned calf leather for daily use. Both materials complement the Everose gold tones without competing with the fluted bezel. For sport or water-adjacent contexts, vulcanised rubber is the functionally sound choice.
How do you change the strap on a Rolex Lady-Datejust 279171-0001?
Strap replacement requires a flat-tip spring bar tool or a 1.8mm push-pin tool to release the spring bars from the 14mm lugs. The operation should be carried out on a soft surface to avoid scratching the Oystersteel case. Professional assistance from a watchmaker or the Casati Milano atelier is recommended, particularly when fitting a deployant clasp that requires length adjustment.
Are there aftermarket straps compatible with the Rolex Lady-Datejust 279171-0001?
Yes. Any strap with a 14mm attachment width and standard spring bars is technically compatible with the Lady-Datejust 279171-0001. milanostraps.it offers a curated selection of handcrafted 14mm straps made to the proportions of the 28mm Oyster case, with materials and stitching selected to integrate seamlessly with this reference.
How long does a leather strap last on a Rolex Lady-Datejust 279171-0001?
Longevity depends on the material and conditions of wear. A quality alligator strap, kept away from prolonged exposure to perspiration and moisture, retains its structural integrity and colour for 3 to 5 years. Vegetable-tanned calf leather develops a patina over time and can last equally long with standard care. milanostraps.it offers an 18-month guarantee against manufacturing defects on all straps.
