What is the order of heirachy for the Seiko sub-brands?

I believe it is:
Seiko
Pulsar
Lorus
I may be missing one tho...

You want to slot J.Springs in there as well. I would have them above Pulsar on interesting watches, where others could disagree.

And AKA, Alba, Spoon, Credor, Lasalle, Grand Seiko, Lukia, Wired, RooX, Orient and a bunch of others that are not coming to mind.

Then there are dozens of sub-brands listed underneath each brand (and particularly seiko)
