I have something very similar to that on the bench right now except it is a 7T32 and not a 7T34. Either way the picture says it all. It takes a ton of patience to want to repair either model. A picture like that usally sends the guys who just work on the mechanical stuff running!Just to give you an idea of what is inside a 7T34, see this picture.
The main crown enters from the 9pm side of this picture.
The components are very small and delicate. The movement main bridges (top and bottom) are made of hard plastic.
It is quite easy with force to damage things.
I think it more likely that this has happened than that the crown stem is damaged.
I feel a bit dizzy looking at that lot.Just to give you an idea of what is inside a 7T34, see this picture.

I have a 7T34-6A09, and did the movement and I am a first timer to these
but I did it on my first try and doing another now.
But need those two grayish plastic gears also.
