My old Citizen ran 12 years without any complaints. I had only several problems with the pins of the bracelet. After this clock then stopped suddenly and I also could not awaken, it had to be a new one. Citizen Eco-Drive radio and if possible it should be so, and then saw the clock Internet, buy, receive and be just thrilled. Design, functionality and durability convinces in every situation, just good, good, good. If this clock buy again!
