Define SPRING DRIVE in 25 words or less CONTEST
I've been thinking about my visits to three Grand Seiko dealers in the past few months:
Los Angeles with AndrewD,
Seattle on my boat trip,
London on a recent business visit...
None of the very friendly sales persons I talked with could articulate the operating principles of the SPRING DRIVE - what makes it different from (or the same as) Mechanical, Quartz or Kinetic.
So I am asking for Purists to take a crack at it.
In 25 words or less tell us what a SPRING DRIVE movement is or does; compare/contrast with what we DO understand.

I have a trip planned to visit Japan in October.
I'd love to take a succinct definition with me to offer to Seiko for their use. And there will be prizes!

Ready? Set? Go!
