How do I resync to atomic clock - have been in middle east and now watch is not syncing with atomic clock signal back in the states

Atomic clocks have antennas that are directional and reception may be improved by turning the antenna to increase signal strength. Place the radio controlled clock along a wall or near a window that faces towards Fort Collins. Locate atomic wall clocks at least 4-8 feet away from computer monitors.

Atomic Clock Synchronization (weathershack.com)

It's most likely because of Daylight Saving Time. Your clock receives a signal through the air once a day from the actual atomic clock, much like a cell phone receives the time from your cell phone service provider, and it automatically resets itself to the exact time each time it receives this signal. Remember that the middle of the year (the second Sunday in March until the first Sunday in November in the US) is Daylight Saving Time for much of the United States. The clock has an option that allows you to set whether you are observing Daylight Saving Time or not. If this is set to "off", the time will be one hour behind until Daylight Saving Time ends (November 7th). Make sure this is set properly, and your problem will be solved.

Go into the settings "mode" and set the "city" to "BKK" Bankok.

Sorry, I've no information on the signal strength where you are.

Place the watch near a window that faces Colorado. best reception is at night although you should get a signal during the day where you are. The signal comes from a transmitter in Colorado. Also, make sure your watch is a model with the US frequency as there are different frequencies used in other parts of the world. Read more at http://www.ntp-time-server.com/atomic-clock.htm.

The watch will set itself at specific time set times, this is likely to be at 0200 0400 and 0600.
You will however be required to set the time zone, the switch is likely to be on the back.

Atomic Time Synchronisation:
How does it work.
SHORT VERSION:
Radio set clocks and watches receive a 60-kilohertz, radio signal from the NIST the official timekeeper for the US and is located in Boulder, Colorado. Ft. Collins. they use atomic clocks and transmits this official time via high frequency short-wave and low frequency AM radio signals, satellite transmission, Internet, and via telephone.

This watch will set it's self in a 24 hour time frame. You need only set the time zone your in.

If it does not correct it's self change location in your house. It receives the signal at 0200 0400 and 0600 for the correction.

The transmitter is located in Fort Collins, Colorado. this station transmits the time codes and is best received at night.

Hope this tip helps

I have several of the both watches and clocks and love them.

The manual mode rarely works, because you have to be awake to do it and most of the time the best signals are from 1am to 3am in the morning.

When the logo is not shown in the bottom corner, the watch hasn't got a signal yet. put your watch on a window sill, and hold the Forward buton until the watch says GET! Form there, the watch will either display ERROR, if it couldn't find a signal, or will have the latest and most accurate time. The watch is also probably set up for auto detect, which is best. To do auto detect, before going to bed, the watch will try to get a signal from 12 midnight, to 5 in the morning.

You can get it serviced at www.casiosalesandservice.com or call them toll free 877.659.0761

I also have an OCW-M700 and found the instructions that you download from the casio website good and perhaps easier to follow than the booklet, still does need some patience and but worth it in the end because it is a great watch. The manual time/date setting can be done fairly easily once you are in 'Timekeeping mode' (page 4, bottom right). The applicable download is operation guide 4749. Good luck. Also, you probably dont want to know this but for others out there - they sell for around 600US$ in taiwan if you can find a shop that stocks the casio upper range, taipei airport normally has stock at duty free.
