Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279171-0016?
The Rolex Lady-Datejust 279171-0016 has a lug width of 14mm. This measurement should be taken with a digital calliper positioned between the two metal lugs of the case, measuring the inner opening. Any aftermarket strap must respect this tolerance precisely to ensure correct fitting and visual coherence with the 28mm case proportions.
What is the best strap for the Rolex Lady-Datejust 279171-0016?
For the Lady-Datejust 279171-0016 in Everose gold and steel, the most coherent choices are vegetable-tanned alligator for formal contexts, smooth calfskin for everyday wear, and shell cordovan for those seeking a material with natural patina and superior durability. A deployant clasp in Everose or steel is recommended to preserve the strap geometry over time. All materials must be cut to 14mm with artisanal tolerances.
How do you change the strap on the Rolex Lady-Datejust 279171-0016?
To replace the strap on the Lady-Datejust 279171-0016, a double-ended spring bar tool is required to remove the spring bars from the case lugs. Care must be taken to avoid scratching the metal: protect the case with a soft cloth and work in good lighting. The replacement spring bar must have the correct length for the 14mm opening. If in doubt, it is advisable to consult a watchmaker or specialist atelier.
Is there an aftermarket strap compatible with the Rolex Lady-Datejust 279171-0016?
Yes. Aftermarket straps compatible with the Lady-Datejust 279171-0016 must conform to the 14mm lug width and use standard spring bars. Milano Straps and the Casati Milano atelier produce bespoke straps compatible with this reference, available in alligator, calfskin, shell cordovan and rubber. Artisanal precision and accurate cutting are essential to ensure secure fitting and a finish worthy of the timepiece.
How long does a leather strap last on the Rolex Lady-Datejust 279171-0016?
The lifespan of a leather strap depends on the material, frequency of use, and care. A quality vegetable-tanned alligator strap, worn in rotation with other straps and kept away from excessive water and perspiration, can last between 3 and 7 years while retaining its shape and lustre. Calfskin has a slightly shorter average lifespan but develops a distinctive patina. Shell cordovan is the most durable among bovine leathers. Casati Milano straps include an 18-month warranty against manufacturing defects.
