Frequently asked questions
What is the lug width of the Rolex Lady-Datejust 279166-0013?
The Rolex Lady-Datejust reference 279166-0013 features a 28 mm case with a lug width of 14 mm. This measurement should be verified using a digital calliper positioned internally between the two lugs at their narrowest point before purchasing any aftermarket strap.
What is the best strap for the Rolex Lady-Datejust 279166-0013?
For a platinum 950 case with a blue ice dial, the most suitable strap is a vegetable-tanned alligator with a centre-cut grain, preferably in cool tones such as navy, midnight blue or slate grey. Heel thickness should not exceed 2.5 mm to respect the proportions of the 28 mm case. A deployant clasp in brushed steel or platinum completes the pairing while preserving the strap's geometry over time.
How do you change the strap on a Rolex Lady-Datejust 279166-0013?
Changing the strap on this model requires a springbar tool or a flathead screwdriver sized for 14 mm spring bars. The platinum lugs have a curved profile, so the replacement strap must have compatible tapered ends. Work on a soft surface to avoid scratching the case and never force the spring bar beyond its seat. If in doubt, a watchmaker or the Casati Milano atelier can perform the operation safely.
Are there aftermarket straps compatible with the Rolex Lady-Datejust 279166-0013?
Yes. Milanostraps.it offers a selection of aftermarket straps with a 14 mm lug width compatible with the Lady-Datejust 279166-0013. Casati Milano handcrafted models are made to millimetric tolerances calibrated for Rolex 28 mm lugs, available in alligator, box calf, shell cordovan and vulcanised rubber. For a bespoke piece with custom-tapered ends, an atelier appointment can be arranged.
How long does a leather strap last on a Rolex Lady-Datejust 279166-0013?
Longevity depends on leather type, frequency of use and exposure conditions. A quality vegetable-tanned alligator strap, worn regularly but not continuously, will retain its structural and aesthetic integrity for 3 to 5 years. Box calf develops a patina but may show wear at the keeper after 2 to 3 years of daily use. It is advisable to remove the strap after prolonged contact with water or perspiration and to store it away from direct heat sources.
