I like Casio, I have owned quite a few, and find them inexpensive, functional and more expensive looking than they are, this one was no exception.
I think I got a bad one, which I had to return though (I'll come back to that)
I wanted a watch rated to 200m Water resistance, the 100m rated Casio I have is good for snorkeling and swimming, but I keep it away from warm water. I wanted this one for Scuba down to about 30-50 feet.
This watch is not too big, a lot of divers watches look like you're wearing a jar lid on your wrist, and that's fine for some people, especially when diving for an easy read face, but not practical for me.
That said, I don't have particularly large wrists, and had to wear this on the third last hole on the strap, leaving hardly any to tuck in the retainer.
The strap is also the formed plastic which although not uncomfortable feels a bit rigid, and as said could have been longer, I doubt it will fit some people at all.
The built in light is amazing, you could almost use it as a flash light, with two bright LED's at 12 and 6, that really light up the whole dial.
The Face is easy to read, the date at 4pm is OK, although easily obscured, and the one way bezel is very stiff and fiddly.

About two weeks in to wearing mine daily it stopped for no reason, I assume the screw down crown must have come undone but it hadn't, I reset it and it worked fine again for another couple of days, then stopped again so I returned it, think I just got an unlucky one maybe.

Overall 4 stars for 200m depth, easy read (not too big) face, light and really nice looking.
1 star removed for small strap, and fiddly bezel
