Two tone color
Color: Silver GunColor, Color: Silver GunColor
I guess it’s good enough for what you pay but the band and base of the watch color do not match and it’s noticeable.

Love the blue numbers
Not quite sure how to rate this. It's an attractive basic analog watch; I especially like the blue numbers. And my experience with the reliability and durability of Casio has always been terrific. But... it's huge. I am stunned to see the other review that states that this watch is too small and is suitable only for a child; I think the reviewer must have been reviewing some other model. This one is larger than any other watch I own, including a hand-me-down men's watch that I got from a friend. This is NOT a unisex watch and should not be advertised as such. But if Casio would make the same thing in a women's model, I would snap it up.
UPDATE: When my smaller watch died, I finally started wearing this one. I've gotten used to the size, and now it looks and feels normal to me instead of huge. I adore the blue numbers--they make me happy every time I look at the watch.
