I have used a Casio Databank DB 150 for several years. I upgraded to this because it has more storage capacity. This watch is a great disappointment. The information is very poorly displayed. On the old watch, the name and phone nmuber were on the same screen. On this watch, you get to the name screen, and then have to push another button to see the number. The numbers do not display the way a phone number should. A phone number should display as xxx-xxx-xxxx. The DB 150 used this type of display. This watch displays the numbers like thisxx xx xxxx xx xxIf the phone number is 123-234-5678 it would display it like this12 32 345678I can't believe that they really designed it like this. This watch is not functional to me. I would not recommend this watch to anyone looking to store phone numbers
