Like the Timex I bought for $30 so far. Getting a new band soon.
Also going to grab this Casio and get a new band for it too:
Casio Diver (Submariner clone) This Citizen
CTO looks nice as does this
Promaster Diver.
What do you all like? I like watches with large cases as I'm 6'4" and anything small to medium looks ridiculous on my big arms.
