First... Welcome!! Actually depends what you want? A Jap or Swiss or German or China.. Narrow down the option then it is easier for you to choose.
2.5k for Swiss, you can go for Tissot, Mido, CYMA, Titoni, Ball (after discount, maybe) F.Constant (saw one after discount around 2.5k).
2.5k for Jap, always go for Seiko, Orient or Citizen (not much choice on automatic, I think. Eco-Drive)
2.5k for German, go to red army watch shop.. You can see something there.
Let skip China for now.
