What is the right stem for Omega 196.0078 (cal 1342)

Hi all, good evening.

I bought a vintage omega and I am trying to fix it. The watch was missing the crown and the stem was stuck inside.

I've managed to take it out (though haven't been able to fully remove the movement from the case, gold plated case, see below pic 1).

The stem seems to be attached to a remanent part of the old crown (possibly with glue) and don't know how to remove that bit in order to reuse the original stem (See pic 2)

My options are:

1) find a replacement stem (but don't know what is the right chinese stem for this watch/calibre, already bought some for 1342 movement and don't fit)
2) remove the remanent part of the crown from the stem (with some watchmaker sourcery) and reuse the old stem with the new replacement original crown i've managed to find.

Any help with either of these options will be massively appreciated (or any alternative view to solving this problem).

All good wishes and thanks for even bothering to read this.

You also need a new crown specific to the cal. 1342. The crown looks like this one:


Turning of the crown sets the hour hand. The second and minute hands are set by pushing the center button.

Thank you all for such generous responses.

I do have an original replacement crown (like the one shared by lejaune in the picture), however I am missing the stem. I feel tempted to purchase the stem recommended by Archer, (Looks like 72213409100 for the 16.7 mm long version.) but I am a bit doubtful as when I opened the watch and tried to remove the movement from the case I didn't manage to do so (if anyone knows the intricancies of how to remove the movement from the case for this type of watch, maybe a link to a video, please do let me know - Picture below)

So I am thinking that If I do purchase the stem and then try to put it on the watch and it doesn't work then I will have to figure out how to fully remove the movement from the case (and do a full disasembly of the watch).

Still a bit undecided as the replacement parts on ebay are around 20/30£.

Anyhow, your contributions so far are very much appreciated.

Thanks for your generosity.

All good wishes.

The 1342 watches I have worked on have plastic movement rings around the movement. The movement comes out with the ring first. I can't tell from your picture whether there is a movement ring or not. If not, you may have to take it out from the front.

Tool 106 is a crystal lift, so I guess the movement comes out through the front. Just a guess.

I had come to a similar realisation after failing to take the movement out (and due to the lack of plastic rings inside), that it perhaps comes out the front. I don't have the right tools for that I think, but will start studying how to do that. Thanks again!

I do think your guess is likely correct. Will hope that I can just replace the stem, but otherwise I'll make myself knowledgeable on how to remove the front of the watch in case that is needed. Thanks again!

Wanted to leave a link to a video I made about this work in progress, a few more videos to come as I navigate this learning process.

New at watchmaking and YouTube, so please be patient.

Of course your contributions are fundamental to this exploration process, so again thanks for your continued generosity.

All good wishes,

Your link doesn't work. Here is a clean link to the same YT video,
