Trench Watch Repair

[Alienfox]

I purchased this little trench watch from ebay the other day, the case is silver and in good condition, however the workings are not fairing so well.

 

I started to strip it down today, as I am fairly new to repairing watches I may never get it back together again but I will try, my question is, what sort of movement is it, who made it (no makers mark) can I get replacement parts?

 

The balance spring has broken, and I could not find a pallet? the pallet wheel is different from anything I have seen before, I will try and get a photo tomorrow but i wondered if it needs a pallet?

 

Anyway I have taken images along the way so I can look at them in reverse to try and put it back together, so heres the first image more to follow later.

You won't find a pallet in that one, it's a cylinder escapement which is why the escape wheel looks so unusual.

Replacing the hair spring is likely to be quite a tricky job as you are unlikely to find one that just drops in, you will need to fit and vibrate a generic one which is a fairly advanced processes.

 

If you can identify the movement then your best bet is to go for a donor movement with a viable balance and hair spring.

Good advice from Marc.

If you take the movement out of the case then remove the hands and dial, you may find an identification mark on the other side of the main plate.
