I'm brand new to this forum and very much a novice but have had a real interest in automatic watches for about fifteen years. I have a few and found out recently that my father in law has a vintage Hamilton that I am cleaning up for him. New lizard strap is on the way and I am trying to polish the (plastic) crystal. I'm also trying to get the movement out of the case but that's where my problem is. I'll wait for a reply and then I'll explain. Thanks to anyone who replies!

Thank you all for the replies! The term 'front loader' seems to accurately describe what I am encountering. I was able to pop off the crystal by hand, thinking it was not that securely in place, so reveal the face and hands. The case is solid and the stem runs through a hole, not a slot, so I am unable to remove the movement without first removing the stem, but I cannot access the back of the movement to release the stem (as I have seen in some videos). So . . I'm stuck, but thinking there is a way to pull the stem so I can remove the movement.

Thank you Michael. Any experience removing the stem from a front loader? Seems to be the only way to free the movement, which I would like to do in order to better understand why it won't wind any further by hand (feels like the tension is maxed out but does not run long after being taken off). I probably did not explain that well, but appreciate any thoughts!

This is frequently asked, and should be found by searching, e.g. on google

site:watchrepairtalk.com front load stem

Anyway, either the two piece stem can be freed by slowly turning the crown while gently lifting out the mov.t so the join is aligned, or pulling the crown out with a bit of force.

I don't suppose there's any writing on the back of a case?

notice you actually have two answers up above? That's because there's actually two types of split stems. it's extremely important to know the difference of the two to avoid unpleasant problems.

the more common time which requires just a bit of force is explained at the link above. You can recognize those stems as they have a much deeper cut to allow them to spring apart and survive being pulled out.

then there's the other type that you definitely do not want to yank the stem with crown out as you will damage them permanently and getting replacement components can be extremely time-consuming. Hamilton isn't the only one that had stems like this style. do a search we've discussed this before on the group someplace.

And just like that, the movement came free! Thanks to all for the info. Yes, two-piece stem. It released when I (accidentally) lined it up and came forward in my hand with no pressure. I'd imagine the fit between the two stem pieces is a little loose but I'll likely not try to adjust, thinking that it'll hold together when in place. Watch is running slow, perhaps one minute + per day, and the tension on the wind is maxed. Was thinking it would lessen as the watch runs / runs out, but it's not seeming to. Maybe I don't press my luck?

      We need to identify the movement to help you, but the oldest of these Rolco watches use Aegler-Rebberg movements that lack a calibre number and are very difficult to identify. You may end up having to make or modify a stem to fit . Post pictures of both sides of the movement when you have it and the size of the movement and hopefully it’s one that has a calibre number.  Gruen used a lot of the same Aegler movements at the time and it’s worth comparing your movement with those if you can’t find it labeled as an Aegler or Rolex/Rolco calibre. Best Regards, Mark

      How to remove shock settings from Smiths 512 movement

      By Mercurial · Posted

      The triple lobed spring, as you suggest needs to be rotated to remove it or replace it. Suitably shaped pegwood should suffice, but tools (shaped as you describe) for the purpose also exist.  If you have an assorted of replacement springs, a trilobe style KIF spring of the right size might fit.  The other spring securing the jewel also needs rotating. There is a slight opening in the setting at about the 5 o’clock position in your photo and one side of the spring should be able to be removed  there when rotated into position.  Hope that helps, Mark

      How to remove shock settings from Smiths 512 movement

      By RobS · Posted

      As an update, it transpired the setting on the balance side, with the jewel had one flat end and one curved. When I rotated it enough it popped out. The chaton was entirely conical and a tricky customer but once lubricated and dropped back in I put the flat edge in first and poked it in with the peg wood tool mentioned above (I made it with flattening off the end then sizing with a pencil sharpener before poking a hole in the end) then rotated and it went in well.    For the other side, magnet searching for the spring has been fruitless.    thanks for the link to the other thread

      Omega Split stem issue (will not go back in)

      By Rustinbox · Posted

      Thank you. It didn’t look rusty. For sure old.    Female part was inside the movement, and when I pushed male part, it got broken. I didn’t apply grease. Here is the photo.      Could it be that male part is too thick for some reason?
