Minute hand stops intermittently after replacing battery
I have three $20 watches from two different manufacturers that all stopped working after I changed the battery. They all failed in the same way: After changing the battery, the second hand moves as expected, however, the minute hand will intermittently stop moving. In fact, if I get out a magnifying glass, I can see that the minute hand has stopped making small movements when the second hand ticks. As far as I can tell, none of the hands are rubbing or interfering with each other. Any ideas what I might be doing wrong to break these watches by changing the battery?
