Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279171-0002?
The Rolex Lady-Datejust 279171-0002 has a lug width of 14mm. This measurement is taken with a calliper positioned between the two lugs on the underside of the case. As this is a non-standard width compared to the more common 18mm or 20mm straps, compatibility must be verified before purchasing any aftermarket strap.
What is the best strap for the Rolex Lady-Datejust 279171-0002?
For the Lady-Datejust 279171-0002 in Rolesor Everose, a vegetable-tanned alligator strap with symmetrical belly grain is the most coherent choice for the watch's formal register. Fine-grain calf leather suits everyday wear, whilst vulcanised rubber is recommended for sport or summer use. Shell cordovan is an exceptional choice for those who appreciate patina development and personalisation over time.
How do you change the strap on a Rolex Lady-Datejust 279171-0002?
To replace the strap on the Lady-Datejust 279171-0002, the spring bars must be removed from the lugs using a dedicated spring bar tool or fine-tipped screwdriver. This is a delicate operation on a 28mm case, as the lugs are narrow and require a precision tool to avoid scratching the case. If in doubt, it is advisable to consult a watchmaker or the Casati Milano atelier.
Are there aftermarket straps compatible with the Rolex Lady-Datejust 279171-0002?
Yes, aftermarket straps compatible with the Rolex Lady-Datejust 279171-0002 are available, provided they respect the 14mm lug width and, where required, a tapered end profile. Milano Straps offers a curated selection of handcrafted 14mm straps in various materials and colours, crafted to the same standard expected of high-end timepieces. The full range is available on the dedicated page of the website.
How long does a leather strap last on a Rolex Lady-Datejust?
The lifespan of a leather strap depends on the type of leather, frequency of use, and maintenance. A quality alligator strap, kept away from excessive moisture and prolonged perspiration, will maintain its structural and aesthetic integrity for 3 to 5 years with regular wear. Shell cordovan tends to last even longer due to the density of its fibres. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
