I've had the watch just over a week and have used it doing carpentry and yard work which is how I expected to use it. The canvas band Keeps
the watch nicely in place and the weight is unnoticeable. So far time is perfect. Because the watch has so many functions I knew I couldn't follow
the small instruction booklet(I'm 73 ) so I downloaded a PDF from Casio which stays on my desktop and laptop. Took me a couple of minutes to get
the four buttons on the watch fixed in my mind but no trouble setting analog and digital after that. Guess I would have preferred a video.
I have another Casio which is four years old and still works but I forgot how I had set it so the PDF is probably nearly the same if I ever need it.
For me the only purpose is to use doing rough work but I can see this being really good for today's electronic minded teens.
