Frozen Crown - Csm-Style Automatic...help!

I ordered a watch for a mate of mine in the US from Fleabay.  As another friend had been very happy with his "Winner" automatic and mechanical watches I decided to order the same brand watch for my US friend.  AFAIK, the movement is an automatic Tongji type...21 jewels.  

 

The problem is that when the crown is pushed down so that you can wind it, it is frozen solid.  When you pull the crown out to adjust the time, you can do so without any trouble.  I asked my friend to check if the crown was a screw-down type...no such luck.  Any ideas?  Sending it back to the Fleabay seller would almost cost as much as the watch.

 

Here's a link to an identical watch:

Sounds to me there might be something broken that is causing the watch to foul up.

I thought maybe he had overwound it causing the crown to freeze up but then I remembered that most automatics have protection against overwinding.  The other thing is that my friend is a watch nut like me so I know he wouldn't do something that silly.

 

He said that the crown is stuck fast.  It will only move when you pull it out to move the hands and then it works fine.

Maybe its had water ingress at the crown seizing up the rachet wheel or similar , probably become clear with the caseback removed

No...it was brand new out of the bubble wrap.  My friend says that there is absolutely no movement at the crown when pushed in for winding.  When changing the time and pulled out it is fine.

Congratulations stroppy, I think you have just introduced your friend to the wonderful world of watchmaking!

At the price of the watch he has nothing to loose by opening it up and having a look, sounds like something is jammed or come adrift in the winding mechanism.

Thanks to all who replied with ideas.  I'll try and convince the guy to open the case to have a look.  If it was in my hands I would pop the crown and stem out and give the movement a good blast with an aerosol camera lens spray can but he is not confident in that regard.

      Seitz Tool - Help determine if Seitz or not

      By Hawaiikook808 · Posted

      Thanks, ManSkirtBrew.  I started looking for a setup like yours and ran across this.  It was about half the price of the JKA Feintaster (depending on what auction you were in), and it's a Bergeon.  I bought it because I thought the price was fair (eBay - Buy it now), and I'm a sucker for vintage tools. It also has a table, so it should be easy to use for measuring jewels. I wonder if the the contact points can be changed out. Bergeon seems to manufacture new tables and accessories for the contemporary dial version. What do you guys think of it? I'm sorry this post seems to have taken a detour. I'm new here so let me know if I should start a new topic.

      Winding pinion making

      By nevenbekriev · Posted

      This is a flying cutter, usual one. The cutter itself is shown in the pictures in the first message, it is made of broken tungsten carbide drill bit. I asure that all the angles of the cutter are as they should be. I have video - little older one - that I made when onse making the same kind of winding pinion for a Poljot 2200, which is even smaller than this one. It is not easy to see in the video, but the tool rest moves about 1mm towards the object in Y direction and then returns back untill cutter is rotating. Then the spindle is rotated one tooth ahead and everything repeated untill all teeth are cut.

      After a bit further research could it possibly be an AS 970?

      FHF70 balance jewels settings

      By Bonefixer · Posted

      Latest project was a non-running ebay purchase with an FHF70 movement. I stripped and cleaned it, reassembled it, and got it running. So far so good, nothing damaged AFAIK.  I was oiling the top jewel on the balance (the one in the cock) which was a slightly unusual shock setting. I removed the spring (3 leaves) which was part of a chaton holding the cap jewel. This left the hole jewel behind which I retrieved with rodico and then lost it. I was taking it off the rodico, very gently as I thought, with tweezers, and then it just disappeared.  Fast forward a week, I got a donor movement, non-running, with the plan to just take the shock jewel that I’d lost. It was the same movement but had standard incabloc settings, and was steel rather than copper/brass.  I changed the cock and balance complete and it ran, not very well. I switched the lower jewel setting, cleaned and oiled both jewels and the replacement balance. Without the pallet fork the balance swings very nicely with a puff of air. With the fork in place, balance out, it flicks side to side nicely with power in the mainspring.  Put them together and it doesn’t run. The impulse jewel sits in the fork and it stops.      Any suggestions how I proceed? In case you didn’t follow that I have 2 FHF70 movements, nothing broken as far as I can tell, but mixing up the balance wheels and jewel settings results in a non runner.

      Oh and this almost perfect third wheel pivot and slightly set mainspring  Ah ok yes i see what you mean, good idea. I'll try that if i fluff this one up. The image isn't great quality but i like the idea though.
