Question about Casio A178WA-1AV Wrist Watch
I have the battery in, but I don't know how to put the one the one spring in.
Do I need to activate the new battery to make it work?
The silver spring goes in a very small hole in the plastic casing on the bottom side of the watch located next to the wristband under the sensor. Hope this helps

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.
