Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279381RBR-0025?
The Rolex Lady-Datejust 279381RBR-0025 features a 28mm case with a lug width of 14mm. This measurement applies to the entire Lady-Datejust 28mm family and is the key parameter for determining compatibility with any aftermarket strap or alternative bracelet.
What is the best strap for the Rolex Lady-Datejust 279381RBR-0025?
The Rolesor Everose case pairs particularly well with alligator straps in bordeaux, cognac or dark tan tones, which complement the warmth of the 18-carat rose gold. Alternatively, box-calf leather in navy or black offers a more contemporary aesthetic, while vulcanised rubber is ideal for daily wear thanks to full compatibility with the Oyster waterproofing system.
How do you change the strap on a Rolex Lady-Datejust 279381RBR-0025?
To replace the strap, use a dedicated springbar tool or lever sized for 14mm springbars. Compress and remove the springbar connecting the strap to the case lugs, slide out the existing strap, and fit the new one ensuring the correct 14mm attachment. It is advisable to work on a soft surface to protect the case and diamond-set bezel from accidental scratches.
Are there aftermarket straps compatible with the Rolex Lady-Datejust 279381RBR-0025?
Yes. Any strap with a 14mm attachment and standard springbars is compatible with the Rolex Lady-Datejust 279381RBR-0025. Casati Milano crafts handmade straps with hand-trimmed ends, millimetre-precise fittings designed to sit flush within the original lugs without lateral play. The range includes fine leathers, rubber and fabric options.
How long does a leather strap last on a Rolex Lady-Datejust 279381RBR-0025?
Longevity depends on material and usage. A quality alligator strap with vegetable tanning and leather lining can last between 2 and 5 years with regular care (avoid prolonged water exposure, apply leather conditioner every 3–4 months). Calf leather tends to soften more quickly. Vulcanised rubber requires no maintenance and typically lasts over 5 years under normal conditions.
