My boyfriend used to sell high-end watches and talked about the quality of Casio watches being even better than Rolexes. For Christmas he wanted a calculator watch. After reviewing other Casio watches, I decided this one would be great. Once he received it, we discovered even more cool options! On top of telling great time, date, and calculations, this watch also has a function where the LED turns on with the motion of the wrist to see the time. It also has a data bank to hold phone numbers and multiple alarms! He was impressed. I was concerned that the face might be too big for this wrist but it lays nicely and he says it works great at work and home. I highly recommend this watch!
