Hi I have a citizen eco watch and it will not stay with the right time have to keep setting it I havent worn it in a while so could you please tell me whats wrong

Your watch runs on light, you need to leave the watch under a light source for at least 18 hours, then as long as your wearing it, it should keep running if you are exposing it to light. At nighttime for a couple nights leave it under a light, so it has a good charge and keeps running. If this does not work then you need to call Citizen Watch repair at 1-800-321-1023.
