Selected Grand Seiko quartz model.

Note 1: Seiko re-issued a limited edition of the "Astron" in 2000-1 that used a special version of the 9F movement that was rated to ± 5 seconds per year,but with tuning easily down to less than + - 2 seconds per year.

Note 2: The 9F movement is reportedly designed to run fifty years plus before it needs servicing.
Note 3: Other Grand Seiko quartz models use the 8J movement. Even less is know about this movement again + - 2 seconds a year

Can we have a link please to read more about that 9F movement and the Seiko Astron? So all that Bulova Precisionist is a joke right?
