Casio or Breitling?

After my swatch and swiss army both died on me, I decided to get another wrist watch, not so that I wear watch everyday. I don't. Just since I need to have at least like 1 watch. I am thinking to have 1 that is OK to wear in all cases from very formal to very casual. I initially fixed on Breitling (see the first 4 images). They look very handsome and very popular actually. But when I tried them on I found they are extremely thick and heavy. And did I mention they are very expensive?

After reading some magazine. I decided on Casio MRG-7500BJ. Casio? Formal? --- Yes! However this MRG model only available in Japan. When I bought it (last 2 images), there is no English Manual. But like years later, the English Manual finally out: Link (if the link doesn't work, go to Casio English Support page, in manual timepieces, put in the code 4777 for downloading that manual). But it is still available only in Japan now. After I used this watch I never looked back or looked any other watch. It is solar powered, all Titanium alloy, coated blue Sapphire crystal top, multiband 5 audio transmission calibrated (Unfortunately this feature is not activated in Australia yet, believe it or not, it is already set up in China now.)
