Use the manual. Read the section about changing the Time Zone. TYO is for Tokyo. To download the manual you need the module number, a 4-digit code on the back of the watch.

Hi dibbles624,

You can easily change the time of your Timex watch by following the steps below.

1. With the time and date showing, press the top left button.

2. Press the right top button (this sets seconds).

3. Press the bottom left button. This flashes the hour; press the top right button until you have the correct hour (there is no symbol for am, pm will show if pm).

4. Press the bottom left button, minutes flash. Press the top right button until correct minutes.

5. Press the bottom left button, month flashes. Press the top right button until correct.

6. Press bottom left button, date flashes. Press the top right button until correct.

7. Press bottom left button, day flashes. Press right top button until correct.

8. Press bottom left button, time format flashes (can be set to 24 hour clock). If correct, you're done. Press top left button if you're done (can be pressed at any step if you're finished).

To turn off the chime and alarm: Press bottom left until in the alarm screen. Then press the top right button repeatedly until the CHIME or CH symbol is gone and/or ALARM or ALM to disappear, then press the bottom left button to go back to main time.

Hope it helps.

The reset trick works with other Casio Alarm Chrono digital watches, such as my old Model W-720, as well. After the new lithium coil cell is installed and secured with the spring clip, the watch may show random segments in the LCD display or may simply be blank. Insert a sewing needle, paper clip, or blade of a small jeweler's screwdriver into the hole on the back of the movement stamped "AC" (All Clear) to momentarily connect the gold plated contact at the bottom of the hole to the stainless steel battery clip. The battery clip in most such Casio watches is connected to the "+" terminal of the coin cell. This will reset the CMOS chip and it should start up with the watch displaying 12:00 and the date at 1-1. Then, use the control buttons to set the time and date in the normal fashion.

I have a G Shock DW-004 made in 1997. I had this same problem, and I tried everything to change TO military time and back to standard time. I just read the bit to try and was about to do it. I pressed the top left button to get the time to flash, and hit the light button by accident (the one with the big G on it) and VIOLA! It changed to military time. So in my model, anyway, the G light button (under the display on the edge of the watch body) changed the time to military from standard and back again, when the time is flashing.

Good luck!
