I have taken the plunge into learning about mechanical movements by completely dissassmbling the movement on a Seiko 7002 dive watch. Re-assembly has been good so far, however I'm now stuck.
After re-installing the pallet fork i cannot get the balance wheel jewel (sorry, I know there is a term for that) into the end of the fork. If I attempt to install it sometimes the pallet fork will release the escape wheel and the mainspring will spin all the parts.
My thoughts right now are:
1. I do not have the escape wheel installed correctly and it is not engaging with the other gears.
2. I do not have the pallet fork installed correctly.
3. I am just plain unable to get the balance wheel jewel into the end of the pallet fork and get the watch to run.
Once or twice i have been able to install the balance wheel and screw down the cock and start the watch only to have it stop running after a few rotations of the balance wheel. During these attpemts I have witnessed the escape wheel rotating and the pallet fork moving.
Any help would be much appreciated.
