Of the two, I agree on Omega. I'm wearing my Seamaster Pro Chronograph (which also happens to be a chronometer).

But I have a suggestion for an obvious alternative. The watch you describe seems to be a Rolex Submariner. They're made with either a date or no date, can be had new for not much more than your budget and used for well under. They hold their value well, are tough as nails, and are appropriate for any situation.

I'd really suggest looking at a no date sub for a clean, understated and eternally classy look.
