Oceanus S100 is absolutely brilliant. Solar powered, radio time sync, titanium (so incredibly lightweight), waterproof, and looks like a dress watch. The only downside is they are only sold in Japan so you have to import them.
The T200 is a great option too- you sacrifice the titanium for stainless steel but get more flexibility as the strap is removable (which IMO makes it more versatile). Beautiful dial too. I own one and I've been looking for watches with similar tinted crystal but haven't been able to find any that do it nearly as well.
I have this watch and I love it. It's incredibly light due to titanium case and strap, and very tough with sapphire glass. Solar powered, so never needs the battery changing, and always accurate due to the radio receiver. And I like that it looks good without being pretentious, or a display of wealth. It's just a Casio, but those who know, know.
