Change battery cheap quartz


Recommended Posts

Dear all,

It's my first post here, please excuse if I post to the wrong sub-forum.

I own a small collection of quartz and automatic watches and at least do most of the usual service myself.

A friend of mine gave me an old watch she likes and asked me if I can change the battery. She told me it's around 25 years old and cheap but she likes the dial. It was a present by a french bank she worked for.

All my watches are either press or screw down backs and I have never seen a watch like this. It seems that the only possible way to open the watch is the small plastic notch on the back. I tried to open it with quite some force but it didn't open.

Do I overlook something, is there a special way to open it?

I also got the original case. A note in it says in french that the battery is interchangeable.

Already thanks for all your help!

Best regards,

Martin

The plastic cap is to access the stem release, afterwhich the crystal should pop out by pumping air in it.

If one just pull the stem something will break assuming isn't broken already

It might come out from the front or it might be a Swatch clone which I am afraid means that is not possible to change the battery. Hoping I am wrong though

On all and any Swatch and copies it's possible to change the battery. It's just that some are more difficult than others, and it's not a job intended for the owner.

I now have consulted three professional watch repair shops. Two told me the battery can't be swapped, one told me he will have to destroy the glass for it.

None of the three knew what the plastic cap is for.

Where have all the pros gone .. ? =)

Can you try and remove that rear hatch? I'd try some double sided tape and then suddenly pull on the crystal to remove it. I'd hold off  pulling the stem unless you know how it works.

Also try remove the strap, maybe something hiding behind there!

    • Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!
    • Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?
    • Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.    
    • Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?      
    • Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
