Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 179383-0002?

The Rolex Lady-Datejust 179383-0002 has a lug width of 13mm. This measurement is taken with a digital calliper placed between the two lugs of the case, at the spring bar seat. It is a measurement specific to this 26mm version and is not interchangeable with larger-diameter Datejust references.

What is the best strap for the Rolex Lady-Datejust 179383-0002 in yellow Rolesor?

For the Lady-Datejust 179383-0002 in yellow Rolesor, the most suitable straps are polished alligator in warm tones (cognac, tobacco, dark brown) or vegetable-tanned box-calf leather in black or burgundy. Shell cordovan is ideal for intensive daily wear due to its structural density. A yellow gold deployant clasp completes the pairing without placing mechanical stress on the leather.

How do you change the strap on a Rolex Lady-Datejust 179383-0002?

The strap on the Rolex Lady-Datejust 179383-0002 is secured by standard 13mm spring bars. To replace it, use a spring bar tool with a forked tip to compress the spring bar pins and slide them out of the lug holes. The process takes approximately two minutes and does not require professional watchmaking intervention, provided the correct tool is used to avoid scratching the yellow gold lugs.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 179383-0002?

Yes. Any strap with a 13mm attachment and standard spring bars is technically compatible with the Rolex Lady-Datejust 179383-0002. Milano Straps offers a selection of handcrafted straps made specifically for 13mm lugs, available in various materials (alligator, calf leather, cordovan, rubber) with buckle or deployant clasp, manufactured to millimetric tolerances for a precise fit within the original lugs.

How long does a leather strap last on a Rolex Lady-Datejust 179383-0002?

The lifespan of a leather strap depends on the material, tanning process and usage. A quality vegetable-tanned calf strap with normal daily use has an average life of 18 to 36 months. Shell cordovan and alligator, due to their structural density, can last 3 to 5 years with proper care (periodic conditioning with colourless cream, rotation with other straps, and avoiding prolonged contact with water and perspiration). Casati Milano straps carry an 18-month production defect guarantee.
