My g-shock watch model# DW 5700 displays a rectangular nox in the upper right corner with the letters "REM" below it. I've installed a new battery and this is all I get. None of the function buttons depressed have any effect. What do you think? D. healy

Question moved from Sharp Televisions to Casio Watch.

Every 60 seconds or every 60 minutes? Do you see 'PS' for low power, power saving on the screen. How new is the battery?

"G-Shock WR20BAR" could mean hundreds of different G-Shock models. If yours is an all digital G-Shock, the answer is fairly simple. When looking at the watch face, the upper left corner button is the "ADJUST" button. Press and hold the ADJUST button for a couple of seconds. You should start to see something flash on the display. Some models will have many options to select in ADJUST mode. To scroll through them, press the MODE button, which is in the lower left corner. You set the hour, minute, seconds, month, date, and year each separately. When you are done, press the ADJUST button again and you'll be back to normal time keeping.

If you want to learn more about your G-Shock, there is something called a "MODULE" inside it that is the brains of the watch. You can find that on the back of the watch, outlined in a rectangle. Usually a 4 digit number. You can download the manual for your watch using that number, if you enter it on a CASIO website:

go to a jeweller

Setting the Time
1. G-Shock watches feature a digital display that is set using the function buttons on the outside of the watch face. To set the time, press and hold the the upper left button until the seconds unit blinks on the display. Reset the seconds to "00" by pressing the lower right button.
   
   Push the lower left button to switch to the hours unit, which will start blinking. Advance the hour by pressing the lower right button. If you hold down the lower right button, it will advance the hour unit at a higher rate of speed. Once the hour is set, press the lower left button to switch to the minutes unit. As with the hours unit, pressing the lower right button will advance the minutes and holding it down will advance the minutes rapidly.
   
   Once the time is set, press the upper left button to save the setting.
Backlight
2. The backlight on a G-Shock watch has a manual control and an automatic function that will light the face of the watch whenever the alarm, countdown alarm or hourly alarm ring. To use the manual backlight, press the button on the bottom of timepiece. The light will glow for approximately 2 seconds before going out.
   
   The automatic function is set by pressing and holding the lower right button. When the automatic function is set, an indicator icon will display on the watch face above the seconds unit. You can turn off the automatic backlight function by pressing and holding the lower right button until the icon disappears.
   
   Note that backlight causes a drain on the battery, and overuse of the backlight will greatly reduce battery life.
Setting the Alarm
3. The G-Shock has an alarm that emits an audible tone for approximately 20 seconds when it turns on. To set the alarm, press the lower left button until "AL" displays in the upper left corner of the timepiece. Press and hold the upper left button until the hours unit starts to blink. Adjust the hour by pressing the lower right button. As when setting the time, you can advance the hour at a higher rate of speed by holding down the lower right button.
   
   Once the hour unit is set, press the lower left button to advance to the minutes. Use the lower right button to set the minutes. Follow these same instructions to set the month and day you want the alarm set.
   
   When the alarm time and date are entered, press the upper left button to save the setting. Push the lower left button three times to return the G-Shock to "Timekeeping" mode.

Did the same with my DW-003 and thought I'd broken the Illuminator (and the alarm didn't work). Next battery change was via a shop and the illuminator worked again (as did the alarm). This was just a battery cahnge, rather than a repair job - One of those things, I guess

There is a reset button inside your watch, but I don't think that is the problem. Most likely, there is a spring that makes contact to the watch and the back of your watch case, and it fell out by the person replacing your battery. I would definitely go back to the place where you had the battery installed, and have them take care of the problem buy ordering you a new spring or have them pay for you to send it to Casio.

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.
