I have a Kronotron Pocket Watch that has stopped running. It probably needs a cleaning.  Does anyone know how to remove the back of the watch? Thank you.

It would be helpful to post a picture of the caseback!

Anyway on these watches I guess it a snap back.. look around the edge and you should see a gap where you can insert a tool and twist. If you're going to do it yourself with a knife take precautions as the knife will slip easily and can seriously hurt you.

'Lifetime mainspring'.. to me this usually means a pin-lever movement. not really high-end horology but works OK.

As said. Using a bit of magnification look for a gap in the back to slot a knife in. If not it's a screw back and bezel might be as well but not always. The problem is with this type of case, as you loosen one it naturally tightens the other and they can end up both being very stiff to remove.

modern inexpensive pocket watches tend to have a very tight "pop off" back.  and require a press to re install them.  modern screw back pocket watches tend to have poor threads, so inspect and pry carefully.     vin

A big thanks to everyone who contributed. The case back is a snap back and I was able to find the gap and remove it with my knife and a light tap of my hammer. Karl

    • Hi All, I’m having a hard time finding a balance assembly or even a working donor movement for a Gruen 330.  Any leads appreciated.   Gruen doesn’t stamp the caliber number of the movement but lust in the case back.   
    • Why do you think this is Fontainemelon ?  The balance staff you will need to source separately.  But first it's important to accurately identify what you have there. Research Ebauches Sa, see who was in group, to find the brand that made this movement. 
    • Hi Watchrepairtalk, I have some questions about part sourcing I was hoping someone here might be able to help with. I'm working on an FHF 180 movement with a broken balance staff, broken regulator pins, and damaged cap jewels (both top and bottom). Some Googling says that this is similar to other FHF calibers like 150s, 160s, 180s and so on but I can't figure out what the functional difference is between these movements.  Is there any reason I wouldn't be able to acquire a donor FHF 150 or similar (with no shock protection) and use parts from that or would it be smarter to source replacements individually? Also are there any sources someone could recommend to get bulk cap jewels like this? Thank you for the help!
    • Hello and welcome to the WRT forum.
    • interesting video nice to see the machine what it can do now I wonder what it costs and I'm sure it's not in my budget. Plus the video brought up questions but the website below answers the questions? What was bothering me was the size of his machine 4 mm because I thought it was bigger than that? But then it occurred to me that maybe they had variations it looks like four, seven and 10. With the seven and 10 being the best because way more tool positions in way more rotating tools. Although I bet you all the rotating tools are probably separate cost https://www.tornos.com/en/content/swissnano   Then as we been talking about Sherline. Just so that everyone's aware of this they have another division their industrial division where you can buy bits and pieces. I have a link below that shows that just in case you don't want to have the entire machine you just need bits and pieces. https://www.sherline.com/product-category/industrial-products-division/   Let's see what we can do with the concept I explained up above and bits and pieces. For one thing you can make a really tiny gear very tiny like perhaps you're going to make a watch. Then another version the center part is not separate it is all machined from one piece. Then fills gear cutting machines have gone through multiple of evolutions. A lot of it based on what he wanted to make like he was going to make a watch unfortunately eyesight issues have prevented that. Another reason why you should start projects like this much sooner when your eyesight is really good or perhaps start on watches first and then move the clocks then local we have from the industrial division? Looks like two separate motors and heads. Then it's hard to see but this entire thing is built on top of a much larger milling machine as a larger milling machine gave a very solid platform to build everything.   Then like everything else that had multiple generations are versions the indexing went through of course variations like above is one version and the one below was the last version. Now the version below I mentioned that previously and somewhere in the beginning to discussion and somebody else had one in their picture. As it is a really nice precision indexing. Then I wasn't sure if I had a the watch photos here is his unfinished watch. No he wasn't going to make a simple watch like none of his clocks were simply either what would be the challenge and that.
