You have to first identify the calibre number of the movement in this case im pretty sure its a Lecoultre cal.201 then search for a balance staff for that movement, all the usual places like part suppliers or ebay.

Obsolete clock and watch has them at 25.00 a piece these movement went into aircraft clocks so parts will be scarce and costly 

I recently needed a staff for a military pocket watch calibre 467 £20.00 each I then needed one for a calibre 415 a much rarer movement £8.95 for 12.

So first off you need to establish the calibre.

Thankyou, I quite often get old watches with no makers name or cal numbers so how do u go about searching for a Calibre number if u don’t even know who has made it.

This subject has been discussed at length in various posts on this site if you have the ligne size you can obtain reference books such as Bestfit, Paulsons, flume, Catalogue official and match the setting parts of the watch to diagrams supplied in these books that will allow you to find the maker and calibre because lucky for us these parts are unique to each maker and allow identification, if you dont want to buy these reference books then you can always ask on this site but you would need a picture of the front and back of the movement in order for someone to help.

Search "ranfft database". Has many, but certainly not all.

BTW, that JLC is beautiful, wish you the best in getting it to run again.

      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

      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.
