Went for replacement battery... Was told the watch was broken and I could just keep the new battery...(£20) I got home and watched this video-they put the battery in the wrong way. So thanks to this i got my watch working and gained a new battery for free!!! Thanks
Bought an earlier version of this watch in the 1980's. At a glance, it is identical. It is still working and keeps excellent time. The only problem is the button for setting analogue time is stuck. All I do is flip the battery out. I wait till real time matches the watch and slip the battery back in. There is no light, but a battery lasts 2 or 3 years. So good, I have just bought the current version of the same model!
Apprentice watchmaker here. My teacher taught me to remove the entire movement, inspect button and c-clips. Sometimes you can order parts using module number, or using a "donor" watch. You would inspect button to determine issue. If parts are unavailable you can use the contact point for the button to advance analog time since it's the button mechanism not working and not the movement itself.
thankyou for posting this i have this watch with an expired battery didn't realise the battery retainer lifted as you showed so thanks for that and setting up which will take longer
You can slacken the tiny screw to swing the retainer out of the way. Last time I slackened the screw too far and it came off. At age 90, I couldn't get it back again. Found battery functions just fine without the retainer which is probably intended to provide the earth (ground) as well as ensuring the battery can't fall out. When the back is snapped on, the battery back makes contact and can't go anywhere.
My apologies re my comments about taking the battery out to set the time. I have two of these Casio watches. The analogue time advance button is seized on both models. When I said I flipped the battery out to match the time, I was referring to the earlier one which is model AG-321, not AQ-230. All the buttons are seized on the AQ-230, which is why I bought a new one.
ty for this video it really helped me understand the inside mechanics of my Casio Quartz watch. I have the blue dial with Iron gray bands and I love the over all look of this watch.
Because the button was stuck, I removed the battery to reset the analogue time. Prising up the battery clip as in the video, resulted in the entire module lifting and breaking the fragile moulded o-ring that prevents moisture from getting to he module. I advise removing the o-ring before attempting to open the battery clip. After a struggle I released the clip, removed the battery and pressed the module back into the case. Now the analogue clock was stopped. When real time matched the analogue time, I slid the battery back in, pressed the retaining clip down, refitted the seal into its channel and snapped the back on. The analogue time is now correct
I got this watch in old house that we had brought it doesn’t have that analog button and needs servicing so I just thought to see how it’s done when I saw your case it was made in china and mine is cased in Malaysia so is my watch older or it’s still new one?
