I've had the watch less than a month and I had to return it due to it being defective. I took it off at night and three different times I woke up and the watch was 3-4 hours off. I had to change the time three different times. The watch has been returned to be replaced or refunded and I have not heard anything from Citizen.
If it is not worn for a day or two the “automatic “ feature stops and you have to reset time/day/time. I would not buy another watch without a battery or eco-drive.
