Almost certainly a "Tongji" Chinese standard movement. I have a couple of "Winner" watches which have a skeletonized Tongji in them. The stem should be available. Some of these mechanisms have a slight tendency for the keyless work to jump out of place, or the spring to snap but there are loads of donors on ebay if you need parts, and they are cheap as chips. For example there are also lots of "Atlas Collections" mechanical pocket watches that use the same mechanism, which would have a long stem in them. You can sometimes pick those up as non runners for 0.99p The Tonji is produced in huge numbers by a number of different Chinese movement manufacturers. As a result there a lot of variation in quality. Some of mine are well finished and run very well. Others, not so much. The parts are mainly interchangeable between different manufacturers, since they are meant to be produced to a standard design. I've included a battery for the watch, simply print it, cut it out and place the watch on top of if, and it should revive it immediately. You will need to fit the stem and wind it and give it a service first of course.

The escape wheel can be repivoted. I would suggest putting away this restoration until your skills have caught up with the problem.

In the 1980s, right out of college, I hunted up vintage wristwatches, found the parts, and a watch repair friend would fix them. Well, my career got going, 2 kids, and decades later I'm back into watches. The fun part is I have 40 or so let over from my time in the 1980s. My son and I are slowly getting those fixed up, while we add new watches to our small collection.

No surprise there, it's hardened spring steel which will not bend. There are a lot of parts like that in a watch, even unsuspicious ones, like casing tabs. The recommendation it's always the same, if something doesn't go in or out with no or little effort, stop right there, research, or ask for help. About a new mainspring, if it catches OK to the barrel arbor it's not that you can manipulate it to catch on the winder, even if you could you would then have to mess with it again to catch on the watch.. not a good idea. It's a fact that winders set, no matter the brand or how much you paid for, give no warranty that they will cover perfectly all the barrels and mainspring in existence. So either you mix or match components, sometime make your own arbor, drums, etc (unlikely for a beginner), or coil up by hand. Issues like that are especially common with vintage watches, a lot of good old watchmaking and toolmaking skills are needed. It's not the "click for parts / fit them / get paid" approach that current repairers, especially the official service centers, are able to get by with.

I was doing some chemistry stuff for work the other day, and waiting for a reaction involving some reasonably strong HCl. I was perusing the internet just surfing a brainwave. Aqua regia is one of those ancient alchemical standards involving HCl (and nitric acid, I think, which is also easy to get without any special permits or anything), and it is used to dissolve and recover gold. I have a small handful of 404 failures that were in gold plated cases. They're pretty much trash unless I happen to find a good movement in a borked case that's worse than these are, but honestly I've moved on from that sort of watch personally. Still, if I were to fall down some rabbit hole or another, as is my wont, that involved acquiring huge quantities of gold plated watches en masse (maybe my daughter gets a bug to make watch part art or something), I wonder how many watches it would take to make chemical gold recovery worthwhile? Assume some average size between mens and womens with their respective representation in the market, then round up to the nearest convenient number. It would be pretty cool to just have a "Royal Water" jar on the shelf with something chilling out in it (plus probably another to dissolve whatever lesser metals first), then occasionally swap out whatever is being soaked. Eventually, finish the process and recover some meaningful amount of gold, and melt it into some goofy little thing. A coin or something. Just for giggles.

Hi there HectorLooi, the one on the left is for roller table jewel replacement. Watch this video it shows how to use. Hope this helps. Graziano

You're welcome. Totally understand Endeavor, and you certainly did an amazing job.

An Acora five jewelled quartz (probably a brand of Lucien Piccard) on its way to the 404 club. The quartz mechanism is stamped "Swiss Parts" so in all likely hood it was assembled elsewhere. I would guess this mechanism is probably from the mid 1980s. The Lucian Piccard brand still exists, but they seem to be producing a small number of Japanese movement chronographs these days.

Thank you very much for your kind words and your very generous offer The watch was handed down from generation to generation and to the owner it was important to get the PW back into the condition as it "always" has been. I'm not an expert either and it may well be that you with regards to the hands are absolutely right, but the now sadly late owner used to love the watch for what & as it was. I'm glad I was able contribute. Again, many thanks !

It runs GREAT, but I tried to bend the bent crown back and it snapped. I had another crown on hand with a 3mm extension and it fit perfect on the broken stem, but I have decided its too small...hard to wind...and of course I decided that after I lock-tight'ed it...so a new stem would be handy! After some googling I suspected it might be the CSM, I was just surprised that none of my on hand stems from the china kit matched.

Absolutely. But right now it is all in pieces. I will get puctures of the pieces tomorrow. Right now i just have a sad shot of the tool rest.

Gender fluid?

I'm highly impressed with your ingenuity and your hand repair, and am absolutely NOT an expert in watch repair, but think that the watch hands are not a matched set. The reason being is that I've acquired from my Father's workroom a huge quantity of hands and have both the hour hand and second hand matching your hour hand. At present, I can't find the hour hand to match your second hand though. See photo. I am happy to send you an individual or pair (free) if you think they'd fit. Trust me, I'm not short of pocket watch hands, lol!

That is just right if you think about it, otherwise abuse and unfairness would be way too easy. Anyway immediate dismissal is possible in some cases, e.g. violence. https://www.gov.uk/dismissal/reasons-you-can-be-dismissed My post had nothing to do with labor regulations, unions or the like, but rather with honesty or lack of it, because I know for a fact that the shop "laboratory" is most likely an unregistered individual. The other nice episode was when mom was charged nice money to repair her old washing machine, she complained about it making a strange noise, the guy replaced a solenoid. Of course that didn't stopped the noise that was due to some lose drum spring or mounting. The old machine was eventually replaced, and I still have the perfectly working "broken" solenoid, in fact it seems to me it's a new part still boxed. I guess the moral of all this is, when someone close to you need some repair don't be lazy and try to fix it right away.

Also had trouble with that issue in the past. Especially a very flat mainspring (0.63) nearly drove me mad. Finally I designed a little tool and a friend with a 3D-printer produced it for me. Once screwed down it holds the spring and its ring tight on the barrel. Then I can just push it down with a brass screwdriver. No „flipping out“-danger anymore.
