It's a pretty  common  part. But you will need to measure  it's  dimensions. For this you will need a set of calipers. You will  need to know it's  length  and diameter. Then you can  order  the part. You will  probably  also need  a stem and a crown  as  well. These parts  are pretty  universal. You can find them on the esslinger website.they have a considerable  variety. Removal  isn't too tough. Needle nose pliers.just be careful  not to bugger the case. Correction...the stem is not universal..they are particular  to the movement  and the threaded  end comes in different  diameters as well..they are known  as tap  sizes.

I found out the non universal thing after I went through 2 stems to find out I needed a split stem. P.s (Does it make a difference if it is a one piece case)?

Hi there , yes it will make a big difference . If it is a one piece case you will need a split stem to remove the movement from the case .You need to pull the stem and split it ,then remove crystal and the movement will fall out the front . If it where a full stem you wouldn't be able to get the movement out .  Hope that helps

      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.
