All our metal components undergo a special anti-rust treatment for jewellery.

Colonna watches do not require any special care or maintenance. However, normal use can result in wear.

With the passing of time, the metal parts are affected by atmospheric agents, acidity from the skin, cosmetics, perfumes and chemical products which darken their surface and eventually lead to rusting.

We therefore recommend storing the product in its case when not in use.
