7T62 Movement: Button A doesn't work after battery change
Took my Seiko SNA553 to a watch shop to have the battery changed. Got it back, now the chronograph is constantly running and can't be stopped.
Pulling the crown out to the second click and holding in both A & B buttons doesn't reset the watch. It appears the watch is not registering any A button operation. The B button seems to work normally.
Opened the back and can see that the A button is working a small lever when it is pressed.
Any ideas on how to stop & reset the chronograph, or to investigate the button operation further?
