I have always liked Casio products and looked forward to receiving my new watch. Upon receipt I went through the manual and got the features set up. I would have deducted another star because I wanted an atomic solar watch. This watch is not atomic however I should have researched more and so the fault is mine.
The reason for the three stars is the face- it is "too busy"- ie, too many non-essential features- I live in the desert- I don't need to know when it's high tide The black face with all the features makes it EXTREMELY difficult to read the time and is a major negative, which is why one wears the watch to begin with. Unless the watch is in a direct light source I can not read the time.
The watch itself is a nice looking watch, but I suggest you stay away from the black face.
