Strap for Rolex Lady-Datejust 179313

The Rolex Lady-Datejust 179313 has a lug width of 13mm. This measurement is specific to the 26mm diameter version and should not be confused with the Midsize variants, which feature wider lugs. To ensure a correct fit, the internal lug width should be measured with a vernier calliper before purchasing an aftermarket strap.

For the Lady-Datejust 179313 in yellow gold Rolesor, a vegetable-tanned alligator strap is the most coherent choice both aesthetically and technically: the belly scale texture complements the Fluted bezel and the leather develops an elegant patina over time. Box-calf offers a more everyday alternative, while shell cordovan provides a unique patina for blue sunburst dials. All straps must be strictly 13mm lug width.

The strap on the Lady-Datejust 179313 is secured to the case via 13mm springbars. To replace it, use a springbar tool to apply lever pressure and release the bars from the lugs. Care must be taken to avoid scratching the Rolesor case: it is advisable to protect the lugs with PTFE tape, or to entrust the operation to a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 13mm lug width is technically compatible with the Lady-Datejust 179313, provided the ends are shaped to fit the curvature of the Oyster lugs. Milanostraps.it offers a selection of handcrafted straps in alligator, calf leather, shell cordovan and rubber specifically made for this size, with colour and buckle customisation available through Casati Milano.

Longevity depends on the material and frequency of use. A quality box-calf strap, worn daily, typically lasts between 18 and 36 months. Vegetable-tanned alligator, being denser and more compact, can exceed 3 years while developing a noble patina. Shell cordovan is the most durable among smooth leathers. All Casati Milano straps carry an 18-month warranty against manufacturing defects.
