Call 5711.
I have a 5712 too and love the 5711.
Except the fact I like the style much much more than the Aquanauts, I also find its finish more to my taste.
The design is much more elegant too, imho of course.
The Aquanaut is sportier and I would less be scared to bring it (hence harm it) when doing sports than with the 5711. It's the only reason I would choose the Aquanaut over the 5711 and this is not enough for me.
Tell us when you've made up your mind.
