2556 stopped getting any time sync signal. - Casio Watches

I have a number of these Casio and Citizen watches. This watch does not use GPS for the time keeping. It uses a land based broadcast time signal. There is public information about where the signals come from for your area. The technical breakdown of the time code signal is public access information.

The instruction manual of the watch has the information about when your watch should automatically receive the time signal, and how to set up the watch. Many of the manuals also included a map showing the time signal coverage, and includes the time of day information to show when the signal is strongest.

Make sure the watch settings are for your time zone. This is important. If the main time zone is not for your area it will be trying to receive the signal at the wrong frequency at the wrong time of day. There are areas where the signal may not be able to be received. You can get the mapping for this from the service that the watch has been set to use.

In North America the auto time receive is supposed to take place between midnight 00:00 to 04:00. In the eastern part of North America the reception is poor compared to central and western part of North America. Check the instruction manual for your watch for details.

Below is the spec listing of your watch.

The point of a radio-controlled watch is that you should not have to move the hands manually. It is meant to respond to a time signal send from various places in the USA, UK, Germany, Japan and (I think) China.
The signal's strength varies considerably, depending on where you are located and the ambient temperature. It may need some application and persistence to get the watch synchronized with the signal, this will cause the hands to move to the correct local time - even then it may need correction if you are in a different UTC time zone or on Daylight Saving Time (DST) locally. Not knowing the make complicates the validity of any information.

I have found that the sync signal is broadcast on the hour for about five minutes and is best received at night where the signal travels further.
Ensure your watch is fully charged and leave your watch by a window overnight for best results.
If you still have difficulty, use an internet search to find the nearest broadcast station to where you are and work out which direction-facing window is best sited to face it.

I have two RC watches - one Citizen and one Casio. One likes to have the left side of the watch facing the window and the other favours the 12 o'clock facing the window, As I don't know the make of your watch I would recommend trying to place it in various orientations until you find one that works for you. I have found the whole set up performs best in cold air situations - and so are more reliable in the winter.

Guessing further, If you bring up the signal display function it may force the watch into signal sync mode - always remembering the 'on the hour' signal broadcasts. You may also find a way of adjusting the hour to suit if it differs for you once it is synced.

I have a new Citizen watch with World Timer. I want to set the time manually and turn off the world timer. I never want to receive the signal..... The book is no help.
