This reset trick works with other Casio Alarm Chrono digital watches, such as my old Model W-720, similar to your F91-W. 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.

In the Alarm Mode, use D to scroll through the alarm screens until the one whose time you want to set is displayed. 2. Hold down A for about two seconds until the alarm time starts to flash. This is the setting mode. 3. Press C to move the flashing between the hour and minute settings. 4. While a setting is flashing, use D (+) and B (-) to change it.

• When setting the alarm time using the 12-hour format, take care to set the time correctly as a.m. (no indicator) or p.m. (P indicator).

5. Press A to exit the setting mode. To test the alarm In the Alarm Mode, hold down D to sound the alarm. To turn an alarm and the Hourly Time Signal on and off 1. In the Alarm Mode, use D to select an alarm or the Hourly Time Signal.

• When the alarm you want or the Hourly Time Signal is displayed, press A to toggle it between on and off
• The alarm on indicator (when any alarm is on), snooze alarm indicator (when the snooze alarm is on), and the Hourly Time Signal on indicator (when the Hourly Time Signal is on) are shown on the display in all modes.

To stop the alarm Press any button.

ebay, craigslist?

The hour hand will advance when the minute hand makes a full rotation

I own the a same CASIO PRG-240 watch.I think there is no problem.Charging every solar powered watch under direct sunlight has to be made in a well lighted and ventilated area, such as balcony and never behind a window glass.Charging from LOW to FULL is a long way (see instructions).Now showing FULL and when removed after a while, MEDIUM, is normal as the battery is not really fully charged.If you use an incandescent light,place the watch at least 50-60 cm distance from it.Usually there are no great results with the incandescent light.I never use this option. Wear your watch for a couple of days (a week for example) under sunlight as much as possible and check.If it still shows MEDIUM after a time period, may be a battery replacement will solve the problem.

mcdevito75 Here, The battery could be loose makeing a weak connection or the LCD screen could be going bad, Have a small watch repair shop in your area check it out. If you can do so yourself be very carefull as too much pressure on the battery (PRESSING) could destroy the LCD face of the watch, also if the display (FACE) of your Casio ever goes black, even if display returns, the LCD is going bad.

If that's from the very start when you bought it, it might a factory defect and you cannot do anything about it. That is already considered a junk. Buy another one.

Anything more detailed about the replacement of batteries? Also, need to know placement of springs. Found a third tiny spring on my screwdriver magnetic) which may or may not be part of the watch… sigh!
Thanks!

Hey all. The charge provided by the solar cells on the watch only really extend the life of the battery. The total run time of a battery depends on how the watch is used... backlight requirements etc. The battery will be depleted and need to be replaced.

Here is a site that has good instructions on how to change the battery in your G-Shock watch.

If you want to ensure you still have a the same water resistance rating, I do suggest that you take it to a watch guy to have it replaced for you. They clean switch contacts also and you keep water resistance rating. Good Luck and vote this as a "FixYa". Cheers
