There are videos on Youtube on how to poise a watch balance. I cannot find a video on how to straighten a balance wheel. It depends what the balance is made off, some are so brittle they cannot be straightened and just break, many just crack. Have you tried to buy a replacement? or is it obsolete.

Seen them to. But's was the use to have a balance tool like this if you can't straighten it.  At least a little.  I guess if you do it in the tool the pivots will bend or break. Btw i bought this old tool  this yesterday. Had a wobbly Enicar/AR balance yesterday. Okay it worked but would have been great to fix some of the wooble.

The tool should be made in a way that it supports the staff on the conical area not the pivots. There are oddball variations. Supported on that area you can use a surprising amount of force on the rim of the balance. Fried's book and others cover it well, I'm sure DeCarle, Chicago or Bulova school texts, it's a common procedure.

      Movement inserted from crytal side

      Before putting it back in the case I would fit the hands and use a pin vice on the stem to make sure the hands were in line.

      Put the movement in a movement holder and it will be supported as you push down on the setting lever post to release the winding stem. Make sure the post is over the shoulder of the movement holder so what you are pressing down on is supported. As a general rule, hold the movement and not the movement holder. Replace the hands when the movement isn't in the case and support the centre jewel (if it has one) on a hard surface or staking block when replacing the hands to stop the jewel accidentally moving or even coming out. A dedicated movement holder with a central jewel support is even better, but pricey

      It might help us if we knew which watch like model number.

      Hi, guys I have a bit of a predicament and hopefully, somebody can advise. I'm working on a Roamer MST 521 where the movement is extracted from the crystal side. I'm now at the final hurdle where I need to replace the movement back into its case but I'm not sure of the correct procedure. I still need to fit the hands but that's where the problem lies. If I insert the winding stem to test the hands for correct alignment I will need to turn the movement over to release the stem again it's the spring-loaded type and needs a small bit of force to push down but with the hands fitted, I don't think I can do this on a cushion without causing some damage to the hands and that's the last thing I want to do, this watch has already been a love-hate relationship and I'm so close to boxing this one off which I'm counting as my first major project.  The other option is to case the movement then fit the hands and hope everything is okay. I've already broken the original winding stem but managed to find a replacement, the last one in stock, so I'm a bit reluctant to keep removing it. Any suggestions would be appreciated.
