Strap for Rolex Datejust 6517

The Rolex Datejust 6517 has a lug width of 18 mm. This is the standard measurement for the 26 mm case variant typical of this ladies' reference from the 1960s–1970s. Always verify this dimension with a calliper or millimetre ruler before purchasing an aftermarket strap, measuring the internal gap between the two lugs.

For the Datejust 6517, a vegetable-tanned alligator strap with a stainless steel pin buckle is the most coherent choice for the model's vintage aesthetic. Smooth or boxy calf leather in cognac, tobacco, or burgundy tones is a refined and slightly more accessible alternative. For daily wear, a nylon NATO strap offers lightness and versatility without compromising the piece's character.

To replace the strap on the Datejust 6517, remove the spring bars securing the bracelet to the lugs using a spring bar tool or a forked-tip screwdriver. Work on a soft surface to protect the case. If you are not familiar with this operation, it is advisable to consult a watchmaker or visit the Casati Milano atelier.

Yes, any strap with an 18 mm lug width and standard spring bar holes is compatible with the Rolex Datejust 6517.

Casati Milano straps come with an 18-month guarantee against manufacturing defects.
