Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279171-0019?
The lug width of the Rolex Lady-Datejust 279171-0019 is 14mm. This measurement is taken with a digital calliper placed between the inner parallel surfaces of the lugs where the spring bar is seated. It is specific to the 28mm case of the Lady-Datejust line and determines compatibility with all aftermarket straps.
What is the best strap for the Rolex Lady-Datejust 279171-0019?
For the Lady-Datejust 279171-0019 in Everose Rolesor, the most successful choices are square-scale Mississippi alligator for a formal register, or vegetable-tanned calf leather for everyday wear. Shell cordovan suits those seeking a low-maintenance leather with a natural patina over time. In all cases, straps must be specifically cut for a 14mm lug width.
How do you change the strap on a Rolex Lady-Datejust 279171-0019?
Strap replacement on the Lady-Datejust 279171-0019 is carried out using standard 14mm spring bars. Using a spring bar tool or a dedicated fork, compress the spring bar ends within the lugs and slide the strap free. It is advisable to work on a soft surface to avoid scratching the Oystersteel and Everose gold case. The Casati Milano team is available to assist remotely via WhatsApp if needed.
