Ah...right up my alley. I am a watch freak. My favorite one is my Seiko Chronograph. Tag Heuer makes some nice ones but I only have an F-1 (non chrono) it has lost 3 seconds in 5 years on the same battery. I have an Aquaswiss chronograph that is really cool looking, but doesn't have as many bells and whistles as the Seiko, but it keeps good time looks good and has better night time visibility.
I have an Accutron as well....but I really don't see the difference in functionality and looks over a Seiko half the price.
Casio is the king of bells and whistles but doesn't carry the prestigue of some of the other brands. Bulova has a pretty nice selection, though I don't have one (yet). They have a really nice divers watch that has depth and other goodies on it.
Look at www.ewatches.com they have some really good prices and a huge selection.
