I agree 100% to Strict Quality control and fine assembled >>>
But all other tests are just to make allot of noise around the watch and make it Greater.
You can take the most complicated movement put it in a case with out any Shocks
and antimagnetic Rings/plats/Tests...ect... and it will work just fine.
I do want fine parts and fine assembling, All other tests are mostly for marketing issues.
Even a JLC's 1000 hour's master control can go bad one day after you bought it.
