Strap for Lady-Datejust 28 Rolesor Yellow Fluted / Oyster / MOP

The Rolex Lady-Datejust 279173-0014 has a lug width of 14mm. This dimension is standard for Lady-Datejust models with a 28mm case and should be measured using a digital calliper positioned between the lugs at the point where the strap meets the case. Straps of a different width will not fit correctly and may cause damage to the lugs.

For the Lady-Datejust 279173-0014 with a mother-of-pearl dial and yellow Rolesor case, a vegetable-tanned alligator strap is the most appropriate choice given the watch's level of refinement. Cognac and midnight blue are the colours that best complement the iridescent mother-of-pearl and the yellow gold bezel. For more active use, smooth calfskin or FKM rubber provide excellent performance.

The strap is replaced by removing the spring bars that secure it to the lugs. A fork-tip spring bar tool is required to avoid scratching the gold and steel surfaces. The operation should be carried out on a soft surface, and if in doubt, it is advisable to entrust the work to a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 14mm lug width is technically compatible with the Lady-Datejust 279173-0014. The handcrafted straps available on milanostraps.it are made to precise millimetric tolerances for this specific dimension, ensuring a snug fit without play. It is also important to check whether the strap ends are straight or curved to match the profile of the Rolex lugs.

A quality leather strap — alligator or vegetable-tanned calfskin — typically lasts between two and four years with daily wear, depending on exposure to perspiration, water and UV light. A deployant clasp significantly reduces mechanical stress on the strap during opening and closing, thereby extending its lifespan. Casati Milano offers an 18-month guarantee against manufacturing defects.
