My GP 18 ct. quartz cal.352 finally failed. I have bought a new/old plated watch & intend to swap movements.
How is the stem removed?

 

At a watchmaker's shop.

 

If you want to do it yourself, there are lots of youtube videos showing you how. Here's one:

 

Thanks, The 352 calibre is a bit more difficult than the standard mechanicals, but an interesting video.

 

I would try unsrew that bold that is nearest to stem and case. Max 2rounds and try to taje out stem. If that does not work.....watchmaker

 

Thanks, came out like a dream. Now to make the swap of movements!
