I bought this watch because of the waterproof aspect. I go swimming in the ocean, play in the sand, go cycling, and never take it off. The face is just the right size for my wrist, not too big or too small. and the black on black look is great.
I would rate this watch a 5 out of 5 but my watch gains 5 to 7 minutes a month. So every month, I have to adjust the time. You would think, that Seiko could have fixed the problem by now. Its a little annoying.
