Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279178-0019?
The Rolex Lady-Datejust 279178-0019 features a 28mm case with a lug width of 14mm. This measurement is specific to the Lady-Datejust family in the 28mm diameter and requires straps produced to this precise dimension to ensure correct fitting without risk of scratching the 18-carat yellow gold lugs.
What is the best strap for the Rolex Lady-Datejust 279178-0019?
For a 28mm yellow gold case, alligator leather with a gloss finish is the most coherent pairing with the aesthetic of this timepiece: the Mississippiensis scale texture complements the lustre of the precious metal. Alternatively, a vegetable-tanned cordovan develops a characterful evolving patina over time. Both options are available in bespoke 14mm straps crafted by Casati Milano.
How do you change the strap on a Rolex Lady-Datejust 279178-0019?
The strap on the Lady-Datejust 279178-0019 is removed using a spring bar tool to compress the spring bars within the lugs. Care is essential: the yellow gold lugs are susceptible to scratching if improvised tools are used. It is advisable to entrust the operation to a watchmaker or to use a coated-tip screwdriver, working on a soft, protected surface.
Are there aftermarket straps compatible with the Rolex Lady-Datejust 279178-0019?
Yes. Any strap with a 14mm attachment and standard spring bars is technically compatible with the Rolex Lady-Datejust 279178-0019. To maintain aesthetic consistency with the yellow gold case, it is recommended to choose straps fitted with a yellow gold or gold-tone buckle or deployant clasp. Bespoke straps crafted by Casati Milano are made to calibrated tolerances matching the original Rolex lugs.
How long does a leather strap last on a Rolex Lady-Datejust 279178-0019?
The longevity of a leather strap depends on the material, frequency of wear, and exposure to perspiration and moisture. A high-quality alligator strap, with proper care, typically lasts between two and five years of regular use. Cordovan and vegetable-tanned leathers of adequate thickness tend to last longer, developing a rich patina over time. Casati Milano offers an 18-month warranty against manufacturing defects on all atelier straps.
