Lady-Datejust 279171-0011— lug 14mm

The Rolex Lady-Datejust 279171-0011 has a lug width of 14mm. This measurement is specific to the 28mm case of the Lady-Datejust range and should be taken with a calliper directly between the case lugs at the strap attachment point.

For this Everose gold and steel reference, straps in vegetable-tanned alligator or shell cordovan with a deployant clasp or buckle in rose gold represent the most coherent choice in terms of quality. Box calf leather suits a more formal register, whilst vulcanised rubber is recommended for aquatic or sporting use.

The strap is removed using a 14mm spring bar tool with a forked or pointed tip. Care should be taken to avoid scratching the Everose gold case. Those unfamiliar with the process are advised to consult a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 14mm attachment is technically compatible. Artisan-made straps are preferable to mass-produced alternatives for this format, as they ensure correct proportions between layer length, keeper thickness and tip finishing — elements that are visually critical on a 28mm case.

Longevity depends on leather type, tanning method and daily use. A well-maintained vegetable-tanned alligator strap, kept away from prolonged moisture and cosmetics, can last between three and six years with regular wear. Shell cordovan, being denser and more resilient, tends to last longer and develops a distinctive patina over time. Casati Milano offers an 18-month guarantee against manufacturing defects.
