I have been researching watches since Roo got my juices flowing. I've been looking at the Citizens EcoZillas and several Seikos, including the Monster. I'm leaning toward the Zilla becasue of its eco drive (solar powered) capability. I currently have a Citizens Eco Drive and not having to worry about batteries, watch winders, etc., is nice. So, Monsters or Zillas....what's not to like?
