I just purchased a Seiko Samurai for the hell of it...
The lume on this thing is AWESOME! Seiko's LumiBrite is as good if not better than SuperLuminova....
I'd also like to point out that, from what I've read, Seiko has been producing their own in-house movements and components LONGER than Rolex has... Seiko was founded in the late 1800s, Rolex didn't exist until 1910 or so...
Seiko is one of the only companies that makes ALL of its own components... their movements are all completely in-house, they manufacture their own cases, lume, etc...
Pretty amazing what you can get...
Also, their "Magic Lever" autowind system is so simple and efficient it's amazing that no one in the Swiss industry has copied their design...

Edit to add:
Good video of Seiko's new SpringDrive (Pug may have posted this, so, apologies if you've already seen it) (Movement stuff starts after like 4:00)
