I ended up putting this particular watch together out of two different movements.  It doesn't matter which set of hands I use they won't move unless moved by the stem.  At first I thought they were loose but that's not the issue.  So basically, I can't figure out why I can set the hands but yet they don't move on their own.  Thank you for any help.

Edit. Second hand does move.  Not hour or minute.

Loose canon pinion.

I made me this contraption to tighten canon pinion with, dull the cutting edge of the nailclipper, the screw provides a micrometer action to give you more control.

Good luck

Hi   You state that the hands don't move under normal circumstances, does the balance still oscillate whilst in this condition ? If so then you have a drive problem. Uncase the watch and remove the date complication then re fit the hands and run the watch do the hour and min wheels rotate?  and the canon pinion turn, If not do as Joe says and tighten the canon pinion and try again as its the canon that provides the drive.  Whats the caliber of the movement.

Yes,  second hand is going around, what just got me is how I can still set them, yet the watch doesn't do it.   It's a seiko 6602

So the minute gear/ train is OK if you can set the hands.

In case it jumps the date by itself, date complication is OK unless amplitude drops noticably when it gets near to jumping the date.  

Usually hands move easily with loose canon pinion.

      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.

      Movement inserted from crytal side

      By Zedster · Posted

      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.
