I was replacing the battery to my Casio G-shock 2300 and while taking off the black rubbery cover, I noticed a very tiny spring popped off the back of the watch. I´ve seen this spring before during a previous battery replacement, but I´m not sure what to do with it. Affter I put the watch back together - without the spring, I can´t get any sound from any of the buttons/modes. Can anybody tell me how to insert that spring and where? Thanks.
this video will show you were the spring goes next to battery

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.

There is a tiny spring that must make contact with the back cover plate when you screw it back on. If the spring is missing, the piezoelectric buzzer will not work. The tiny spring is located toward the upper right in this photo of a Casio W-94H watch, directly underneath the "C" in CASIO that is etched in the metal. Note that the word CASIO is upside down in the picture, so if you can't see the picture for some reason, the hole for the tiny spring would be directly above the "C" in CASIO.
Choose a quiet, well-lit room where you can replace the battery in your Casio Pathfinder watch. Prepare a table, desk or other clean, flat surface where you can perform your watch repair. Put down a soft cloth or piece of craft felt to protect the face of your Casio Pathfinder watch from being scratched during the battery installation process.
Set your Casio Pathfinder watch face-down on the soft cloth or craft felt. Use an optical-sized Philips screwdriver to remove the four screws that secure the watch back to the body of the watch. Set the screws aside, but don't lift the watch back.
Slide the watch back off of the body of the watch very slowly. There are three important springs held underneath the watch back; it is essential to remove the watch back slowly to avoid losing them.
Lift the three springs out of your Casio Pathfinder watch using a small pair of metal tweezers. Take note of the length and placement of the springs as you remove them. Set the springs aside with the other disassembled watch components.
Take the black rubber protective disk out of your Casio Pathfinder to reveal an identically-shaped white plastic disk. Remove the white plastic disk and set it and the black rubber disk aside. Use your metal tweezers, if necessary, to lift out the rubber and plastic disks.
Release the battery strap that holds the battery in place in your Casio Pathfinder watch by pushing the battery strap latch to the left. Remove the old battery from your Casio Pathfinder using a pair of small plastic tweezers.
Pick up your replacement watch battery with the small plastic tweezers and insert it into the battery compartment of your Casio Pathfinder watch. Replace the battery strap and push it gently with the tip of your plastic tweezers to snap the latch in place.
Touch the "-" and "AC" terminals on your Casio Pathfinder watch with the tips of your metal tweezers for at least two seconds. This helps ensure that your watch will work properly once reassembled.
Put your Casio Pathfinder back together to complete the new battery installation. Start by replacing the white plastic disk, followed by the protective black rubber disk. Use your small metal tweezers to replace the small watch springs in their correct locations. Replace the back cover of your Casio Pathfinder, insert the four screws and tighten them with your optical-sized Philips screwdriver.
