I hear plenty of BS from people saying how great they are and that they intend to buy one, but when push comes to shove they purchase Omegas, Rolex, Breitlings whatever. I'm well aware that Seiko doesn't really distribute Grand Seikos in the US. However, have you considered if they wanted to market and sell them here on a greater scale, then they could. They are not some tiny upstart company. In addition, if someone collects watches, and knows about GS and really wants one, with the internet, or travel there is no reason they can't buy one. However, in its price range their relative lack of status and brand perception does affect their sales. Like it or not there are always people that are going to say for the price of a GS they can have a Rolex, Omega, Breitling, etc. I didn't say that Rolex, Omega, or Breitling were better, just that are more commonly chosen due to the perception that many people have of them being luxury brands. If you think GS's sales aren't hurt by being made in Japan, by being made by Seiko, and a relative lack of association of Seiko products as luxury items...then maybe you are only seeing what you want to see.
It's not BS - they are pretty great. By great, I mean beautiful (if conservative) designs, flawless fit and finish and superb accuracy.
I can't speak for why Seiko chooses to keep the GS line a small and exclusive segment of their otherwise massive (and highly successful) production, and I'm pretty sure you can't, either. But if we are to freely speculate, I would say that they don't actually want them on every street corner.
Of course Seiko is "hurt" in terms of perception of luxury by being made in Japan - ignorance and outright bigotry abound. But as you know, I wasn't addressing brand perception based on country of manufacture - I was addressing the merits of the product itself, and the continued suggestion (that I only ever seem to hear from you) that nobody really buys these things. This simply isn't true. Few are made, and few are consequently sold. The quality of the product is far from BS - rather - it is evident to anyone with experience enough to assess the merits of a fine watch and a sufficiently open mind to make that assessment independent of the country of manufacture or the "story" being pitched in glossy hardcover catalogs. Snow capped Swiss mountains are not an essential environment for the manufacture of a fine timepiece.
It is entirely possible that I am able to see quite clearly in this regard, and your vision that is somewhat clouded.
