The holy trinity...
... of vintage Grand Seiko.
Examples of the three major VFA movements - 6185, 6186, and 4580.
I say major, because in the instance of the 6185, there were 6185A and 6185B variants.
Watches are the 6185-8021-G (date), 6186-8000-G (day-date), and the legendary 4580-7010 (dateless) - which I have recently learned is almost certainly rarer than the Astronomical Observatory Chronometer. But I'll save that story for another time 
VFA stands for "Very Fine Adjusted". When these watches were sold in the early 1970's, they were regulated to +/- 2 seconds a day, and guaranteed to be accurate to within 1 minute a month for the first two years of ownership. Quite simply, the absolute pinnacle of mechanical watchmaking of their time.
Kind regards,

Accuracy within 1 minute per month, guaranteed! Do you know of any modern manufacturers offering any better?
Or was this the pinnacle of mechanical watchmaking accuracy, period?
It is also interesting that Grand Seiko was used as the main brand on the dial. Wonder why they abandoned this practice and began using simply 'Seiko' instead, relegating 'Grand Seiko' to 6 o'clock position?

A very elegant trio.
I must also compliment you on your amazing picture.
Please share a few more pictures.

That no date version is a killer...
Thanks for sharing...I think today only Rolex offers +/- 2s I guess !
GS is a great watch with a good pricing.

Thanks for the info Mahesh
I've heard that Rolexes were particularly accurate, but didn't know they go as far as to guarantee +/- 2 sec/day. Very impressive for Seiko to do this in 70s and for Rolex to do it for a million watches per year they produce
Very rare indeed
Never seen a no date VFA or knew it existed ... a great trio ..,cheers
WOW !!!
Congrats.
The 3 mecanical VFA are stunning pieces.
It is so incredible to see them together, in such good condition.
4580 is so rare, I have never seen it in real life.
Please tell us more ...
