Yes, particularly the high end stuff you can only find in Asia. The Grand Seiko's are on par with the automatics that come out of Geneva. The problem is a lot of what they normally sell in the US is pure junk, so the brand is not well-perceived here.
Yes - they provide great quality and cover a wide range of pricepoints and styles. They may not have the flash marketing or prestige, but if you want to keep track of time around under all sorts of conditions, you could do far worse.
I like that they make there own movements and have had periods of great design. Early in my watch collecting I acquired several automatics that were very well thought out including the Bellmatic - a 27 jewel alarm/day/date, six square chronographs with different dial color combinations. I enjoyed them. Then I got the disease and really started collecting and the Seiko's never got the love again. I sold the autiomatics to collectors in Europe.
