Did not know this Doc !..It seems that practice does make perfect !
What is so impressive about this is the determination to do things right !
Seiko probably could have gone with dozens and dozens of prototypes.
They could have stopped after a couple of years and had a great movement.
However, they were determined to do the BEST job possible. Creating world
class movements and watches was evidently the result..it's pretty outstanding !
I appreciate the info..THX !
