Seem like the pallet fork is not in place correctly, hopefully it has not been damaged by the mishap. Its correct working should have been tested right after installing it.

the pallet fork seemed ok and engaged with the escape wheel and the balance and spun for a while before stopping. i will check that JDM thanks.by the way the photos posted were taken before i stripped it down!

I may have misunderstood what you meant by "everything moves". So it's not like  it spins like crazy when wound. 

If it ran for a while it may still barely move if you touch the balance wheel with a toothpick. In these very common cases something may be rubbing, or otherwise wrong in the area of hairspring, balance, escapement.

Is it in beat? 

not got that far yet.what i meant previously is that the wheel train motion works etc all moved whether the stem was in or out even though the keyless clicked back and forth as they should. nothing is spinning out of control.maybe i should go back in and start again!

Check that the set lever is in the slot. also the set lever could be upside down, ie the side that faces up now should be facing down.  If you took some pics while pulling it apart that would help check if you got it wrong.

Also observe how the set-lever moves when you pull the crown, it should move smartly with no 'sticking'. On some watches (not sure if it applies to this movement) one of the bridge screws (from the other side) is shorter in the area where the set-lever goes. If the wrong screw is used it will interfere with the movement of the set-lever or stem release.

Good luck

      TIMEKEEPING PROBLEM: Impact of changing the platform escape wheel on a carriage clock

      By zygo · Posted

      Fast responses - thank you. Yes, I mentioned the 18000bph to illustrate that it's not a matter of touching coils, over banking, shortened hairspring etc. I even took off the platform and temporarily fitted a another NOS one also with 8 leaves and beating 18000 but the colossal gain is the same. I'm resigned to buying and fitting a new Gorge platform plus a 7 leaf pinion escape wheel but only if I think it will work; otherwise it's a waste of £200 and a couple of hours work. Hence the underlying question is: all other things being equal, what would the timekeeping effect be? Is it a simple 7/8ths as fast? Logic tells me it is but can it be that linear?

      Sorry to jump in here guys, but I've read through this whole thread and it seems there are a lot of people who think joining Facebook means everyone will have access to their lives. You could make a Facebook account with a fake name. You could even use your real name if you wanted to and set it to completely private so people can't even find you in a search and you don't have to add anyone as a 'friend', so you won't see anyone's posts. Literally use it to join a group full of members of this site. Admins could even set the group to private and require a password of some sort to gain acceptance into the group, so you can be sure that it's only members of this site that get in. @tomh207 is right, the form with email addresses and names is a bad idea. That will be abused by scrapers. Facebook is only as personal as you let it be. You can be completely anonymous on there if you wish. Don't think of it as Facebook. Just think of it as a watch repair group as that's all you'd use the account for. It doesn't even have to be set up with your current email address. Make a random one on Gmail or any other free provider just for the Facebook account. Tagged you by accident and now it won't let me remove it 😂 @Neverenoughwatches

      Hi I'm a new member.  I recently pulled a Wakmann 8 hour clock out of one of my small airplanes.  My hope is to get it working again.

      Dangerous substances when disassembling timex indigloo?

      By watchAdventures · Posted

      I have a timex urban command (digital watch with indiglo). Are you aware of any dangerous substance or material that I can come in contact with if I disassemble the watch? For example I read that the indigloo is made of luminescent “indium tin oxide” (as reported here https://www.chemeurope.com/en/encyclopedia/Phosphor.html) and that this material can cause irritation to the respiratory tract If inhaled (https://en.wikipedia.org/wiki/Indium_tin_oxide). Any other stuff I should be aware of? Thanks in advance for your answers.
