How do you change battery on casio 1346 module watch, I notice in back of watch there are six slot.
Harbor Freight sells a low cost watch wrench but in a Robinson Crusoe situation you can CAREFULLY use square nosed needle nose pliers(Lowes or The Home Depot won't object if you try out one of theirs); hold watch in wash cloth to protect your hand, put the square blades in the watch back indentations and slowly turn with maximum pressure, after it opens use a quality Japan Maxell SR621W silver oxide, do NOT use a China alkaline version as they leak and have less run time. Use a Q-Tip with light Vaseline around the sealing edges when reassembling. Sincerely batteryBob
