"AC" means All Clear. This terminal should be marked somehow. Use a magnifying glass to get a good look at what you are working on. My Casio had an arrow pointing to four copper leads. I used a paper clip to connect the AC terminal (I just picked one of the four) to the + side (usually the "up" side) for a couple seconds and my Casio Sea Pathfinder model 2273 powered right up. See the following link for more guidance.

Do not lay the tweezers across any contacts as you may damage the watch.
First you need to examine your watch movement and find an AC point (contact). It is embedded on movement. Use an eyeglass, as the writings can be very tiny.
When found, touch an AC point with one arm of tweezers and battery+ with another arm simultaneously.
Some watches needs to do that twice, so, to be sure, do that twice.
If
you are not comfortable with tweezers, you can use a thin wire,
connecting one end of the wire to AC point and another to battery+.
Each shortcut should last for 3 seconds.

You can do it yourself. Unscrew watch caseback and undo the contact on top of battery. Read the writings on battery and buy exactly the same one. Do not mind manufacturers (Casio, Maxell, e.t.c.), just make sure the numbers are the same.
Some watch casebacks can be opened only if the watch band is removed, so, remove it if needed, just don't forget to memorize where every part and screw was fitted. Memorize how the battery is fitted and do not put the new one the other way around as this can damage your watch.
Actually there is nothing difficult - only you have to put everything back exactly the same way as it was. If your watch will be left without battery for more than 3 minutes, you will need to reset your watch after replacing a new battery, but it's easy if you've got users manual.
Good luck.
