This older Casio model comes with some cool features. They are all hidden inside. 
The model is called Flip-top Calculator. The word "calculator" basically explains everything. But not completely. Look at the dial - everything seems to be as usual: marks and hands. Where are the buttons and screen for arithmetic operations? Under the dial! 
The watch was released in the early nineties and was accompanied by interesting advertising. The advertising posters read, “Half of you want to look good, the other half want to look smart.” Like, the watch is both beautiful and can count.
This model, by the way, can still be bought on the Internet - for about 200-250 dollars.
