Hi All

A couple of weeks ago I was trawling through an old curiosity shop near me and I noticed about three old movements in a draw of old bits and pieces.  I picked one of the three and paid a small amount for it - just for the fun of fiddling with it.  I had no idea what it was or whether it would work.  The balance moved freely - thats about it.  So I disassembled and cleaned it.  The only issue - of my doing - was that the balance cock has two male locating posts which were a fairly snug fit, and in the process of prising it off , the balance cock flipped over tangling the balance spring. I chased the twist down the spring (should have gone up) but it is now mis-shapen beyond my skill level. Everything else is assembled and moves freely, so I am a little annoyed with myself as it would have likely been the perfect restoration were it not for my ineptitude (OK, early skill level).

I now know that the movement is an AS324 (A.Schildt) circa 1925. Non-shock.

I would love to find another or a balance just to prove (almost) that I could finish it.  Any thoughts?

Cheers Jon

Common wrong approach even by pros is how you proceeded detaching cock-balance assembly. 

Best to loosen cock screw , not entirely and not remove it, then pry the cock to loosen/ disengage  it from the locating pins. 

Under the remarks subtitle, Dr ranfft list many calibers which practicaly are the same as AS324, the balance complete of any  fits your watch.

Good luck pal.

Excellent advice!  Thank you.  I shall also check out the other calibers.

    • Hold the crown when in winding position, move the click away from the crown wheel, and then while holding the crown let it slowly unwind. I recollect that you must remove the automatic device bridge first, but maybe I'm wrong. You can first try without removing the automatic device bridge.
    • nevenbekriev- You nailed it with your description of me and my reaction when the clock started ticking again. I am a newbie.  I love the sound and idea of mechanical clocks but the idea of owning one and trying to keep them running has never appealed to me. My wife bought this one and an antique German wall clock.  When I looked into having someone repair them for me, the universal response was "it's really expensive to work on them, you should just replace the movement". So, I had nothing to lose, I started researching them and opened them up. The wife is happy because she hears the sound of the clocks again. But I have gone down the "accuracy" rabbit hole. In the vertical position, the balance wheel was not floating. It was sitting on the bottom of the frame. I adjusted the lower spring collet and got it floating. It easily passed the 270 degree 3 to 5 minute oscillation test. It took 8 minutes for the wheel to completely stop moving.  I put it the unit back in the movement and checked the safety pin. It does not touch the safety roller anywhere in +/-270 degrees rotation from neutral position. But the amplitude of the rotation with the spring fully wound is weak based on what you are saying. It rotates +/-90 degrees from the neutral position.  No, I did not take the movement completely apart.  That seemed way outside my skill set at the time. There is a reason I became an electrical engineer and not a mechanical engineer. I am much more comfortable with moving electrons than tiny moving metal parts. Will I do it in the long run? Anything can happen. I don't seem to be able to let it go.
    • Isn't that the same guy who told Zelenskyy to escalate the war with Russia/Putin when they already had a peace deal? 2 years later and we have half a million young Ukranian boys dead. He doesn't seem very clever...
    • Thanks guys.  quick question. For automatic movement, particularly this one. can I power down the main spring by pushing this rachet down?  i've gotten pretty used to SW210 and powering down a manual movement. But so far i've only been waiting for the auto movement to run out of juice before opening the case.
