Recent purchase is an Illinois 16s 17 jewel pocket watch.
Not running and when balance wheel is shaked the second hand isn't moving.
I pulled reg cock and found only a hole in the balance table.
I see there is a pin sticking up from the pallet fork.
What at is this pin for? It looks like it would fit into the hole in the table. Is this possible?
is there supposed to be a roller jewel in this hole? If the pin has any significance what is it?
i haven't tried setting in the wheel by aligning the pin in the hole, so I don't know if I'm chasing a fault in my strategy.
I know that a roller jewel will engage the fork opening of the pallet fork and that the roller jewels detach making no link for the escape wheel thus no running of the hair spring.
So, do all tables have a jewel or is this hole supposed to mate with the pin of the same diameter as this hole sticking up just behind the fork opening? If I must shellac a jewel onto the table what then is the purpose of the pin on the pallet fork?
