Maybe you should check out the watchuseek forums. There are so many options and many styles you can choose from. You should also mention what style do you prefer (dress, dive,...) and what type of budget (you said limited but exact price range is more help full ie. <1000, 1k-2k, 2k>)
If your price range is above 1k, Ball is an excellent choice (http://ballwatch.com/
). If you look around in the market place, you can score some nice ones under 1k.
For under 1k range, Steinhart is a strong company with many glowing reviews for their watches (http://www.steinhartwatches.de/en/
). I've been lusting over their Ocean 1 GMT and Apollon for a while now.
Read around a bit and pick out what fits you best. Hope you score yourself a beautiful graduation watch.
EDIT: I surfed watchuseek and saw you selling your Raven. ^^" You already have a Kingston (which I adore and wished I had one) so you DON'T need a new watch LOL.
