Spring Drives are expensive as hell for Seikos.
It's funny that Seiko is not a status watch yet it makes many high end pieces (Spring Drive, Grand Seiko, etc). They have some fantastic movements though that real watch enthusiasts really appreciate.
Myself... I like to stick to the sub $1000 Seikos. If I'm going to spend $1000+ on a watch it's going to be something like an Omega or a Sinn or something like that. That's just me, though.
The thing about the Spring drive is that because it uses the mechanical movement to maintain a battery charge it's not a true mechanical watch in the sense of only mechanical power. Still very cool, though, if you can afford to spend thousands on one.
