I have a very nice 8B63 watch, SBXY007, which I like very much and was under $600. The only limitation is that, unlike the newest gps dual time watches, you can't switch the times on the main and sub-dials at the push of a button-- which is a handy feature when you are traveling.

I also have a Citizen satellite wave that I love, a green CC3064-01X, but it doesn't have a sub-dial. Also under $600.

I am tempted by the new Seiko movements, but agree that most of them are ugly. I do like several of the newest models that have a porthole date window, as opposed to the off-kilter square windows, which are not to my taste. I don't need a chronometer, however, so that limits my choices for now.
