Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279171-0018?
The Rolex Lady-Datejust 279171-0018 has a lug width of 14mm. This measurement should be verified with a calliper at the point where the strap inserts between the lower lugs of the case. This is a non-standard size compared to the men's models within the same family, so it is essential to select straps specifically made for 14mm lug width.
What is the best strap for the Rolex Lady-Datejust 279171-0018?
For the Lady-Datejust 279171-0018 in Everose Rolesor, a vegetable-tanned alligator strap is the most fitting choice, given the regular grain and three-dimensional texture that complement the 18k rose gold case. Smooth calfskin is the most versatile option for everyday wear, while FKM rubber is preferable for sporting or summer use. All straps must measure exactly 14mm at the lug.
How do you change the strap on a Rolex Lady-Datejust 279171-0018?
To replace the strap on the Lady-Datejust 279171-0018, a dedicated springbar tool or fine-tipped screwdriver is required to remove the springbars securing the strap to the lugs. Care must be taken to avoid scratching the case. It is advisable to have the operation performed by a watchmaker or specialist atelier, or to proceed on a soft surface using proper tools.
Are there aftermarket straps compatible with the Rolex Lady-Datejust 279171-0018?
Yes, high-quality aftermarket straps compatible with the Rolex Lady-Datejust 279171-0018 are available, provided they have an exact 14mm lug width. Milano Straps and the Casati Milano atelier produce bespoke and ready-to-wear handcrafted straps in various materials — alligator, calfskin, rubber, shell cordovan — with buckle or deployant clasp options.
How long does a leather strap last on a Rolex Lady-Datejust 279171-0018?
The lifespan of a leather strap depends on the material, craftsmanship and care routine. A high-quality vegetable-tanned alligator strap, worn with moderation and stored correctly, can last between 3 and 5 years whilst retaining good structural integrity. Calfskin typically lasts 2 to 3 years with regular use. Exposure to water, perspiration and perfume accelerates deterioration; it is advisable to rotate between several straps.
