I would consider them a high end maker. Looking at watches like the Freak, the Sonata (my personal favourite from the brand), and other amazing watches they have made, I don't think you could not consider their work high end.
They do have lesser models, mostly dive watches and many using an ETA movement with a module on top. Those are less high end, but by all accounts still nicely made watches. The old 1846 Marine Chronometer model was one that I loved the looks of, and it if wasn't modular, I would probably have bought one.
I remember myself and 2 buddies all going to a store once where the had 3 of their divers in different colours, and we remarked that we all liked a different version. We nearly walked out with our own version of that watch...
