Totals of up to 9 digits appear in round openings above the bands.The front is ferrous metal painted gold, black, and white. The back is black plastic. A metal stylus for entering numbers is on the right and a zeroing bar extends across the top.
- A mark at the top of the adder reads: W CALCULATOR. A mark below the bands reads: ADD (/) SUBTRACT (/) MULTIPLY. A mark at the bottom of the back reads: MADE IN WEST GERMANY.
