Like all Casio watches is also this very intuitive. The fact that the buttons are left and thus disturb not bend the wrist for left carrier, makes me happy. The design is simple, a beautiful combination of black / gold. And in addition it is completely waterproof. I've already used several times in swimming and it is completely sealed, what I had, however, expected from Casio. Moreover, it is relatively slim and by the strong pre-curved bracelet and the corresponding mounting it is very well placed. At the end of the strap has a slight thickening, so that the protruding strap end can not slip out of the 2nd loop - great for sports.
