A few years ago a friend of mine tried to have some non-watch parts made in China and gave up because he couldn't get it through to the manufacturer that he wanted exact replicas of what he'd sent over, not for them to improve some faults and try to supply better versions!
It sounds good though. I always wanted a 6309-7040 with 20mm lugs, I wonder if someone can make me a new case that's a perfect replica in every other way.
