Strap for Rolex Lady-Datejust 179173

The Rolex Lady-Datejust 179173 has a lug width of 13mm. This measurement is taken between the two lugs using a digital calliper and is the essential parameter for selecting a compatible aftermarket strap.

For the 179173, a vegetable-tanned alligator strap with a symmetrical belly grain is the most fitting choice given the model's bimetallic aesthetic. Smooth calf leather is a refined everyday alternative, whilst a woven nylon NATO offers lightness for less formal occasions. The correct width is always 13mm.

To replace the strap on the 179173, use a fine-tipped spring bar tool to release the spring bars from the 13mm lugs. Work on a soft surface to protect the crystal and case. Alternatively, a watchmaker or the Casati Milano atelier can carry out the swap without risk to the case.

A quality leather strap for the Lady-Datejust 179173 typically lasts between two and five years with regular wear, depending on the material and level of care. Vegetable-tanned alligator and shell cordovan offer the greatest longevity. Prolonged exposure to water and perspiration should be avoided, and a neutral conditioner applied periodically to preserve the leather fibres.
