Why does my Citizen Eco-Drive 8637 second hand move at 2-second intervals?
If the second hand on your Citizen Watch is moving at 2-second intervals or the watch has stopped, it indicates that the charge is insufficient. You should charge the watch until the second hand moves at 1-second intervals.
What to do if the day and date change around noon on my Citizen Eco-Drive 8637?
If the day and date on your Citizen Watch change around noon, it means the a.m. and p.m. settings are reversed. You should set the correct time, paying attention to whether it is a.m. or p.m., especially during the time period when the day hand moves.
