I just acquired this nifty old Timex quartz. It's working, but it has some problems and I'd love some advice on what to do.
First, I had to struggle a bit to remove the old battery. When I popped in the new one, it wouldn't stay in place. It kept popping out. I finally held it on the best I could and quickly screwed on the caseback to hold it into place. Is there a trick to getting the battery to stay in place?
Then I noticed the second hand would periodically pause for a 1-3 seconds. Sometimes it even goes backward by a second. I watched it for a while and I'm not able to discern a solid pattern. But it seems to stop and start near the top of the hour more often then at other positions. What might cause this?
I thought I'd take out the movement and see if there's a problem with the way the hands are attached, but I can't figure out how to remove the stem. Anyone know how?
If I need to replace the movement, does anyone know what type this is and/or whether I can replace it with a modern movement (or an old one salvaged from another watch)?
