Calculator industry has always been led by CASIO. “Time is just a constant addition of unlimited 1 seconds and it’s a very simple adder”. Their mindset is fairly simple and using their digital tech that they learned from calculator, they released the world’s first digital watch with full-auto calendar called “CASIOTORON” in 1974. Since then, an impact resistance watch “G-SHOCK”, humidity calculation, altitude calculation sensor technology, miniaturization technology and so on. Their originality changed people’s perspectives on what the common sense of watches are. “Challenge the common senses, To keep evolving you must keep pursuing” is their bottom line motto and that spirit is the reason why they haven’t stopped being on the top of this industry.
