After a month, the button that adjusts the time fell off. It was within the warranty and the company replaced it for me. The next one I got had problems from the moment I bought it... The stone fell off the dial. I gave it back and they fixed it under warranty... After a while, it started falling behind in time... I took it back and they told me it was the battery... I changed the battery... After a while, the same thing happened again... They got tired of me... Now, within a week, it falls three hours behind... It still has a warranty but I won't go back... I got tired and they got tired of me... I wasted my money...
