However good they may be as a computer (I have no doubt they are) the Ratio watches look clunky and cheap compared to the Suunto watches. Frankly I wouldn't want to to be found floating face down with them.
I think Perdix is the way to go here, as suggested. Great resale value too.
Btw, I looked it up and Suunto prices in the US are totally ridiculous if you ask me.
Ratio has TWO types of computers, wrist rectangular type with big screen that has a very wider angle of viewing (more than any other computer out there) and watch type of computers that are solid computers and the numbers are more clear and easier to read than the Suunto (I have owned Suuntos since early 90's until now). There nothing "clunky" about either version of the Ratio computers, I have tested them in person myself.
I look at them as dive computers not as a fashion statement (Ratio has jewelry decorated version of their watch type computer however. It seems to sell well for them, they are Italians after all )
