Of those, in that budget, i'd choose the 203 titanium. You could also get an arktis in budget, but you might have to be pretty patient and determined. But i almost guarantee that you wouldn't regret going steel over titanium in that case. It's just such an enchanting watch. If you examine all the one watch threads /which watch would you never get rid of /which watch do you regret moving on the most, the arktis always figures highly. Its basically due to a combination of the geek tech and the beautiful dial. If i had to choose between the arktis and the ezm1 as a one watch, i would choose the arktis. It just has the edge. Ezm1 is also lovely but don't think you'd get one in budget. No subdials on there becuase the chrono hands (one minute hand, one seconds) run from the centre of the dial, and the bezel on it acts as a countdown timer, so it has slightly different timing functions than the others.
