Where do the do the "1000 hours" testing

 

I just learned this from looking at my Grand Seiko's certificates that they do 400 hours (17 days) on all their mechanical watches.

Since the JLC talks about the 1000 hours, and that takes 41.66666 days, I suspect there must be a big room filled with winders and such... or are they in each assembly area?
