Casio FlipTop DataBank IA-1000

There is some dust on the keyboard
There are also some slight scratches on the plastic digital display. It was really impossible to keep this watch as new, because the distance between the plastic display and the rubber keyboard was tiny and any dust that remained on the keyboard when closed would start working on the display. I was very careful in the restaurants, a salt grain could have done considerable damage.
Again, despite all the shortcomings I find the flip top concept great. I found it so great that I bought a plastic successor of this watch later. Well, I bought almost all new Casios in the early 90ies :-) as long as they had a DataBank.

Note: the rubber keyboard has now deteriorated and I do not think that Casio keeps spares or is able to fix it today (2011)
