Frequently asked questions

What is the lug width of the Rolex Lady-Datejust 6516?

The Rolex Lady-Datejust 6516 has a lug width of 13mm. This measurement is specific to the lady-sized version of the Datejust family produced between the 1960s and 1970s. Always verify with a digital calliper between the lugs before purchasing any aftermarket strap.

What is the best strap for the Rolex Lady-Datejust 6516?

For the Lady-Datejust 6516, fine-grain alligator or vegetable-tanned calf leather straps are the most coherent choice given the two-tone steel-and-yellow-gold aesthetic. Smooth textures complement the case's classic lines, while a steel or yellow gold deployante buckle completes the pairing without overwhelming the slender wrist profile.

How do you change the strap on a Rolex Lady-Datejust 6516?

The strap is removed by releasing the spring bars located inside the lugs using a 1.2mm flat-tip lug tool or a dedicated spring bar tool. With 13mm lugs it is essential to use replacement spring bars of the correct diameter to avoid scratching the case. If unfamiliar with the process, consult a watchmaker or visit the Casati Milano atelier.

Are there aftermarket straps compatible with the Rolex Lady-Datejust 6516?

Yes. Aftermarket straps with a 13mm attachment are compatible with the Lady-Datejust 6516, provided the strap ends are correctly shaped to fit the Rolex case geometry. Milanostraps.it offers a curated selection of handcrafted 13mm straps in various finishes and materials.

How long does a leather strap last on a Rolex Lady-Datejust 6516?

A handcrafted leather strap on a small-diameter case such as the Lady-Datejust 6516 experiences less mechanical stress due to the watch's reduced weight. With regular rotation between multiple straps and periodic conditioning, the average lifespan is 2–4 years. Alligator and shell cordovan straps tend to last longer, developing a distinctive patina over time.
