Lady-Datejust 279173-0017— lug 14mm

The Rolex Lady-Datejust 279173-0017 features a 28 mm case with a lug width of 14 mm. This measurement, taken internally between the two lugs at the point where the strap attaches, is critical when selecting an aftermarket strap: only a strap manufactured precisely at 14 mm ensures a correct and secure fit.

For the Lady-Datejust 279173-0017 in yellow gold, a vegetable-tanned alligator strap in cognac, honey or bordeaux tones offers the most coherent aesthetic match with the dial and the warmth of the metal. Alternatively, smooth calf leather develops a personal patina over time, whilst shell cordovan provides a compact, densely grained texture of great character. All straps must have a 14 mm lug attachment.

Strap replacement on the Lady-Datejust 279173-0017 requires a spring bar tool to remove the spring bars securing the strap to the case lugs. It is advisable to work on a soft surface to avoid scratching the yellow gold case. For original Jubilee bracelets, removal is carried out via the deployant clasp mechanism. If in any doubt, the work should be entrusted to a qualified watchmaker.

Yes. Aftermarket straps compatible with the Lady-Datejust 279173-0017 must have a lug width of 14 mm at the attachment point. Milano Straps offers a selection of handcrafted straps in alligator, calf leather and shell cordovan specifically produced in this width, with tapering and length calibrated for the 28 mm case. The buckle is available in stainless steel or gold-tone PVD according to aesthetic preference.

The lifespan of a leather strap depends on the quality of the tanning, frequency of wear and exposure to perspiration and environmental conditions. A high-quality vegetable-tanned alligator or calf leather strap, worn regularly but not exclusively, typically lasts between 2 and 4 years. The 18-month guarantee on manufacturing defects offered by Casati Milano covers production faults, not normal wear and tear.
