Our bracelets are not under warranty and their lifespan can vary from several months to several years, depending on the type of bracelet and the use you make of it. Water, sweat, sun and chemicals/cosmetics are all things that can alter the appearance of your bracelet. In summer, or for any sporting and/or aquatic activity, we advise you to opt for a nylon or steel bracelet. The leather could become stained and deteriorate prematurely.
