If you want to get in to automatics, PVN's suggestion of the Seiko SKX779 aka the Seiko Monster is a good place to start.
Alternatives are the Seiko SKX007
Seiko SNM033
Seiko SKZ255
That said, it seems that you are going after analog watches with lots of functions/busy face, in which case I think your choice of Citizen Eco drives are perfectly fine since a reliable mechanical watch with that many functions won't really be in your budget.
