 I have almost no experience of this brand. The whole watch seems in pretty good shape but lacks a crown. The stem is present but is captive in the case. I'm unable to find a crown for it among the hundreds of old crowns I possess. The outer thread diameter is approximately 1.2 mm but has some wear in the part that I can measure although the threads are not too badly damaged. It occurs to me that this thread may be a non-metric size. Also am I correct in thinking that the stem tube has an inner sleeve? I'd greatly appreciate some tips on how to deal with this and trust that the pics are adequate.

It's having a long jacuzzi right now. I have an identical (?) watch which is a potential donor. However one thing that's not identical is the diameter of the stem tube. And it almost looks as though there's a circlip (god forbid) inside the tube. To be continued.

Yes. it withdraws from the inside when de-gunked.

It has a stem retaining sleeve that is screwed out from the top, but you need the correct tool to unscrew it, once you have removed it then the stem will come out.

Here is one on ebay to see what it looks like.

This is also whats clicks the stem into setting and winding positions

Thanks folks!

The stem pulls out readily from the inside. Luckily I have four nearly identical movements and cases (the "nearly" is an insurance policy intended to ward off nasty surprises.) Nice movements but unfortunately the three that have serviceable balances are only seven jewel. Do I feel lucky today?

I'm waiting for a stem wrench (from US) so that I can adjust the depth of the sleeve. However, in the meantime I have two of these Waltham 1907s up and running. Or did, now there's only one. I watched the repair videos on this watch. Even after dismantling and trying to reassemble one I still don't understand how this keyless work functions - having reassembled it precisely as shown, it won't wind. 

Also, I don't think I will ever be able to align bridges and pinions. I'll stick to cleaning with the train in place. Despite thinking that this one's bridge was correctly positioned (it dropped into place with the locating pins in position and the pinions apparently located correctly; but how can you tell?) the whole train is now jammed and what was a working watch with the limitation of a badly adjusted stem is now scrap. About eight hours wasted.

    • Yep…This makes perfect sense. With that large a gap in the serial numbers, they were almost certainly machined on different equipment, hence one should have no expectation of any cross-batch compatibility. I’ll revert to the original bridge. Regarding bending the bridge @nevenbekriev, I’ll give it a try, but I may have to buy some better calipers. My Vernier calipers are only accurate to 0.1mm. Not very accurate. 
    • Yes, what I wanted to say is that the cock is part of the main plate, manufactured together with it and not meant to be interchangeable. Even if the other cock gets in place, it is not sure that the balance then will stay upright. You should use the original cock when it exists and is not destroyed. The adjustment needed by bending it is not irreversible. It is minimal deforming that is needed. No tools are needed. I have pointed to all needed references here for the balance staff endshake checking and correctness confirmation. The only tool needed for the correction is You thumb. The cock must be fixed on the main plate, no need of special plate with holes and so on. If You will feel more confident, then measure with Vernier caliper the height of the top of the cock where the stones are against the main plate bottom when the shim is fitted and try to reach the same height when bending the cock (with no balance in place!!!) Caliper with screw for fixing is perfect.    
    • Thanks for the reply. I polished the head of the screw using 1500 to 10000 lapping paper and a screw polisher. This is why I think the head blued and the rest of the screw didn't. Silly question, how do you polish the whole screw inc threads, if that's what it needs to blue? 100% clean, Elna red and heated ultrasonic bath + IPA rinse. Finally, there is definitely heat leak as there's about a 30c difference between the brass bed and the soldering station temp. Having said that, the bed temp was stable. I will try to search out a better brass pot, but I haven't found one yet, hence the stainless steel bowl. 
    • Agreed but that's where WD40 excels, water displacement. 
    • I would change the container to a thick walled brass one to start with. Looking at you screw pictures they don’t look shiny enough, really it’s best to do a black polish on them before trying. Also make sure once polished they are scrupulously clean, I dunk my experiments in acetone before bluing.   i think the thin walled stainless container to leach away the heat from the shavings, most successful bluing videos for example use thick walled brass to hold a good deep amount of shavings which acts as a better holder of heat.   Tom
