Yup! it was a big thing then, then moved to G-Shock....then to Brietlings......then suddenly everything was gone, and now just a cell phone.

This is not the DATA BANK model; it is only calulator and time alarm clock. However, that is my preferred requirements anyways; so this deal is good....assuming you can tolerate the green color model. Bought 1 just now thanks.

I have 2 of the scientific calculator watches from the early 80s. They were awesome! Now our phones can do all that and more.

I loved the databank watches when i was a kid.
Then switched to Palm Pilots.

Brings back memories.
But why buy it now a days?

And why all of a sudden (past couple months), all these classic Casio watch deals on SD?
