Your Watch is in Auto or demo mode. Hold down the "Mode" button for 3 - 5 seconds and it will return to time keeping mode.

I'll post in case somebody still needs this. This is the general procedure to switch the ATC 1200 from meters to feet. You can also switch the ATC 1200 (1170) from C to F. This is very helpful if you change the batteries and the watch gets reset to meters.

Also note, when you pull out the two batteries, you may not get the watch to come up. This is because of a race condition when the watch gets power. To fix this, look for the AC mark on the inside of the watch. Under this marking, in a little space to the left, are two copper pads. Short this out with a small screw driver to get the watch to ground zero.

To fix the Metric measurements:

1. Go to the home screen on the watch. This is when the the 3 letter abbr for the day is at the top. Also, if you cycle the mode button, it is the screen where the final beep is "high."

2. Then press the "memory" button, which will take the home display to the data screen. This shows current time, pressure and temperature.

3. Hold down the adjust button, until the set screen comes up.

4. Tab the mode/select button on the watch until you get a flashing C. Then press the memory button to toggle to F.

You can adjust all the measurements from this screen.
