Rating : - Easy to use convenient calculator and great casio quality This watch is really helpful when shopping or just when you need to calculate something quick. It's handy to have in match class. The buttons stick out so it's really easy to use. Some newer casio watches don't have the buttons sticking out and makes them harder to use. The watch is waterproof and I wear it in the shower to see if I'm taking too long so I'm not late for work. The dual time option is great if you are traveling. The battery also lasts a long time, I've had the same watch before and it lasted over 3 years. The stopwatch is really nice for exercising and the alarm is loud too. Overall a great casio watch.
