Serial Number 843000 was reported as inaccurate.

Note: 843,000 can not be a railroad grade pocket watch
as it is definitely pendent set. I am in the
process of cleaning this movement and it is
certainly pendent set so therefore can not be
railroad grade. Also, movement is marked ADJUSTED
+ Temperature. Not marked to 5 positions.
Everything else is correct...
