I think it's a question of marketing and brand placement. There's a certain cachet, with some folks, if a movement is in-house- it definitely shows a company commitment to engineering and design, but to the end user, other than wanting to identify with that brand of watch- does it truly matter?
I'm just as happy with my cheap $20 Casio quartz watches, as I am with my Orient automatic. As long as they can tell time, it doesn't matter to me. If I could buy a Rolex Sub with a quartz movement, far cheaper than what they are now- would I? Hell yes I would.
But conversely, if you could buy a Porsche 911 with a lowly 6cyl from a Buick, would you? You could still get places, but the experience wouldn't be the same.
With watches, I just want it to look cool, or quirky, and I want to like it. Oh yeah, and tell time. What's on the inside doesn't matter to me at all.
Nice collection, I've got a 5-6 collection myself, and feel pretty good about it. I do have a tendency to look at various Casio's. Definitely need more of them.
If it's truly a "grail watch" - which I would take to mean one you've researched, liked from afar, wanted, desired for quite some time- and if it doesn't cause you any financial hardship- go for it! I have a very small collection thus far, and not really sure how much money I'm willing to pour into this new obsession, but I get just as much satisfaction from a $40 Casio Duro as I do from a much more (but not crazy) expensive Seiko. But- to each his or her own.
