FAQ
What is the lug width of the Rolex Lady-Datejust 279171-0021?
The lug width of the Rolex Lady-Datejust 279171-0021 is 14mm. This measurement is taken with a digital calliper, positioning the tips on the inner walls of the case lugs. It is the standard lug width for Lady-Datejust models with a 28mm case diameter and should not be confused with the 13mm found on older references or the 16mm of larger variants.
What is the best strap for the Rolex Lady-Datejust 279171-0021?
For the Rolex Lady-Datejust 279171-0021, with its Everose gold and Oystersteel bi-colour case, the most suitable straps are vegetable-tanned alligator in smooth or hornback grain — in shades of bordeaux, cognac or chocolate — or shell cordovan for those seeking an exceptional progressive patina. For sporting or summer use, a vulcanised rubber strap is a clean technical option. All straps must feature a 14mm lug attachment.
How do you change the strap on a Rolex Lady-Datejust 279171-0021?
To replace the strap on the Rolex Lady-Datejust 279171-0021, you will need a fine-tipped springbar tool with a 0.7mm tip, suitable for the 28mm Oyster case lugs. Compress the springbar ends within the lug holes and slide the strap free. It is strongly recommended to work on a soft surface to protect the case and sapphire crystal from accidental scratches.
Are there aftermarket straps compatible with the Rolex Lady-Datejust 279171-0021?
Yes, high-quality aftermarket straps are available for the Rolex Lady-Datejust 279171-0021. The key specification is a 14mm lug width. Milanostraps.it offers a dedicated selection of 14mm straps in leather, rubber and fabric, handcrafted to be geometrically and aesthetically compatible with the 28mm Oyster case. Bespoke options are available through the Casati Milano atelier service.
How long does a leather strap last on a Rolex Lady-Datejust?
The lifespan of a leather strap on a Rolex Lady-Datejust depends on material quality and daily care. A vegetable-tanned alligator or shell cordovan strap, with regular use, typically lasts between 2 and 4 years. Exposure to perspiration, water and perfume accelerates deterioration. Storing the strap away from heat sources and applying a neutral leather conditioner periodically will significantly extend its life. Casati Milano straps carry an 18-month warranty against manufacturing defects.
