1979 Timex quartz M56 stem


Question

Hello all, I have a 1979 Timex Q quartz watch with M56 movement.  When I disassembled the watch for maintenance, I messed up the stem.  I can now easily pull the stem all the way out. So now instead of setting the time, I have the watch in one hand and the free stem in the other.  Does anyone have advice on how to secure the stem properly? 

thank you, Martin

Welcome to the forum Martin.

You will need to reset the keyless works, assuming nothing is broken.

There are others here well versed in the Timex world. I'm sure they'll be around shortly.

You need to bend the brass tab circled in red back up into place to hold the stem. You must have pressed too hard when removing or it was a already deformed. In the hand setting position the brass tab stops the watch when it contacts another brass strip that goes to the circuit board and stops the stem from pulling out.

You may have to remove dial to do this operation.

Love these jump minute watches!

Thank you so much for the welcome and for the advice!  I was able to adjust the contact from the dial side, pushing it back into place to secure the stem.  In the patent for M43 (similar to M56) it is part number 46 that needed to be adjusted. And it is this same part that needs to be pushed a bit out the the way to remove the stem.

 

The watch came to be in bad shape and needed to be cleaned, oiled and polished.  Now the watch is running well and yes, the jump minute is very nice!  

 

I added images of the drawing for part 46,  the dial side of my watch with the exposed piece of part 46 pushed back into place, and the finished project.

Thanks again for the help!  Martin
