If you want DW just buy a fake 10$ one. seriously not worth their full retail price (i suggest you google the article about how DW makes money with cheap watches)
Since you don't know what you like just see the popular models for each brand lor.
Seiko:
SKX007 / 009
Seiko 5 lineup (most affordable quality automatic watches under 100$)
Alternatively (

Orient:
Bambino V1/2/3
Mako / Ray
Flight
Citizen:
Nighthawk
Promaster Marine
I suggest starting with Japanese brands first since they really are the best bang for buck for a first watch
