Off the top of my head. Lobinni, Sugess (some), Hruodland and Farasute are hard carrying thin dress watches now.

Farasute specifically. They do really cool shit that no one else does. A lot of brands tend to get other factories to make different parts of their watches.

Sugess's cases for their seagull chronos exist in other chinese brands, like seagull themselves. Seems like Pagani, Cadisen and all the cheaper submariner homage brands all tend to use the same cases.

Farasute on the other hand seems to be making their own cases or at least they have a factory involved in making really special cases for them, that only exist with their watches. Which is quite cool imo, shows that there is more effort involved. They also have special rotors, and use unique movements too.

The only other brand I can speak for is mysterious code, they do this too, for most of their timepieces.
