Lady-Datejust 179171-0073— lug 13mm

The Rolex Lady-Datejust 179171-0073 has a lug width of 13mm. This is a non-standard measurement compared to most men's Rolex models and requires straps manufactured specifically to this exact dimension to ensure a proper fit between the lugs of the 26mm Oyster case.

For the Lady-Datejust 179171-0073 in Rolesor Everose, alligator straps — particularly Hornback or Mississippiensis grain — in cognac, burgundy or plum tones complement the warmth of the 18-carat Everose gold. Vegetable-tanned calf leather and shell cordovan are equally refined alternatives. All options must be produced at exactly 13mm to fit the original lugs correctly.

Strap replacement requires a springbar tool to remove the spring bars securing the strap to the case lugs. Given the narrow 13mm lug width and the delicate Everose gold surfaces, it is advisable to have the strap changed by a watchmaker or experienced technician to avoid scratching the polished case or damaging the lug ends.

Yes. Artisanal aftermarket straps compatible with the Lady-Datejust 179171-0073 are available, manufactured to a precise 13mm lug width to fit the 26mm Oyster case. Milanostraps.it offers a curated selection of 13mm straps in alligator, calf leather, shell cordovan and rubber, with pin buckle or deployant clasp options, all dimensionally verified for compatibility.

The lifespan of a leather strap depends on the material and how it is cared for. A quality alligator strap, worn in rotation and kept away from prolonged exposure to water and perspiration, can last between 3 and 7 years while retaining its structural and aesthetic integrity. Vegetable-tanned calf leather develops a pleasing patina over time but is more susceptible to moisture. Casati Milano offers an 18-month warranty against manufacturing defects on all bespoke straps.
