I owned a Casio W-201 for many years. The 10 year battery finally gave
out, I bought a new battery and like with all my previous Casio watches proceeded to install it myself.

I opened the back, but could no find any way to get the old battery out! The Casio manual suggested it should be taken to a dealer, but this not easy in a remote place in Canada.

Still, I happened to go to the big city, and once there went to Sears who are dealers for this watch. I asked their watch repair man to put the new battery in while I watched. No problem, the repairman showed me how to get the battery out and how to install the new one, while he did all the work.

Problem was when he was finished, :oops: he could not get any of the 4 setting buttons to work!

Well, lucky me, the store still sold the same favourite watch and I bought a new one. But I asked the repair man to give me my old watch back, because I decided to see whether, with a bit of fiddling around, I can find out what why the setting buttons stopped working.

Once back home, I took the old watch apart again looking for any mechanical problem of the button operated switches, but could not find any.

In the process I took off the entire metal mask on the back of the watch display chip, which also holds the battery assembly. Inside I found a tiny loose spring. I read before on a Watchuseek post that this spring is part of the watch's alarm bell.

So now I am trying to find out where to put the spring back in its proper place and how to attach it there. I am also curious why the setting buttons do no longer work. Does anybody have any ideas? :roll:

Did the wtachmaker reset the module after exchanging the battery? :think:

Im not shure about your watch and if there is a reset contact somewhere.

Look at the module and search for a stamp "AC" somewhere.
If you find a contact labeled with ac you can short it to the battery for a second and look if the module is awake again.

Thanks for trying to help.

The watchmaker said this watch has no requirement to reset, and it also has no AC contact mark. He said it sets itself, and the way to check whether it has reset is to hold the watch up to look at the display screen, and if it is showing watch time of 12:00 it has reset!

I do not know whether this is true. But the watch showed this time.
Problem was it could not be set for the real time, because the buttons did not work:-(
