Deconstruction video made up of photographs from stripdown of the movement.


On stripping down this scrap movement I found the following items that need attention.
Firstly the whole movement is rusted up, the mainspring and balance wheel did not move.

During the deconstruction, I found the mainspring had been fully wound up and this caused the click to be jammed on ratchet wheel, plus the barrel was stuck to the barrel bridge by dried out grease!

After carefully taking and train wheels out from the movement due to them being very tight in the pivot holes, it is clear the whole movement had been over oiled, and because the movement had not been used for a long in oil had dried out and everything had become stuck.

One Dial and case screws are missing, and the roller table on the balance staff is loose.

So now the movement is completely stripped down to its fifty-nine parts, it’s time to clean all the items well.
