L.ancien band had lasted two years, the new not even 2 months (without having done nothing special) the small plastic part of the clasp broke ... And the guarantee does not ... I have been to the jeweler who m 'has a steel clasp for 5 euros ... the it's tough! You should know that this box that sells spare parts is not Casio ... So for the purchase of the new watch: Casio, for repairs: the jeweler because it is cheaper and more strong!
