As a rule, I love casio watches (and calculators! lol). This one is very nice, it is NOT bulky, and it is actually quite thin. IT tells the time well, of course, and it has a great range of functions, such as timer, stopwatch, 5 Alarms, a world clock, and you can set the time, date, and year very easily. The LCD display actually turns off after about 6 hours of being in the dark. Less then half a second in the sun will turn it back on automatically. All in all, a very good watch!
