Lady-Datejust 279178-0024— lug 14mm

The Rolex Lady-Datejust reference 279178-0024, fitted with a 28mm yellow gold case, has a lug width of 14mm. This measurement is standard across the entire 28mm Lady-Datejust family and should be taken with a digital calliper between the lugs on the inner side of the case, after removing the original bracelet.

On an 18-carat yellow gold case, an alligator Mississippiensis strap with natural tanning offers the most coherent combination in terms of material quality and visual harmony. Shell cordovan is an excellent alternative, developing a distinctive patina over time. For the clasp, a yellow gold deployant buckle is the most stylistically consistent choice for this reference.

To replace the bracelet or strap on the Lady-Datejust 279178-0024, you will need a fine-tipped spring bar tool with a 1.8mm point. Compress the spring bar ends inward within the lugs, applying gentle pressure to avoid scratching the gold surfaces. Rest the case on a soft cushion and work in good lighting. If in doubt, consult a qualified watchmaker or the Casati Milano atelier.

Yes. Any strap with a 14mm lug width and standard spring bars is technically compatible with the Lady-Datejust 279178-0024. Milano Straps offers handcrafted leather, alligator and cordovan straps made to precise millimetre tolerances, suitable for the model's gold lugs. All available options can be found on the dedicated 14mm strap page.

The lifespan of a leather strap depends on the quality of the tanning, the hide thickness and frequency of wear. A high-quality alligator or cordovan strap, vegetable-tanned and silk-stitched, can last between three and seven years with regular use, provided it is kept away from water, perfume and heat sources. The 18-month production defect guarantee offered by Casati Milano covers any structural imperfections not attributable to ordinary wear.
