Casio, LTP-1234PGL-7A2EF, Casio Collection, 32x21mm, Watches

Casio was founded by the four Kashio brothers: Tadao, Toshio, Kazuo, and Yukio.
Led by the second eldest, Toshio, the four brothers developed the 14-A, the world’s first compact all-electric calculator, and established Casio Computer Co., Ltd. in 1957. Each brother brought his unique specialty and strength: Tadao in finance, Toshio in development, Kazuo in sales, and Yukio in production. Taking on a specific role and working closely to complement each other, the brothers grew the new company together.

 

The company emblem is a design that encompasses and highlights the Casio trademark with a circle of four Ks, the initial letter in Kashio. The emblem symbolizes the strong ties among the four Kashio brothers that founded and developed their calculator business. Toshio Kashio, inventor of the Casio calculator, designed the emblem himself to embody their approach to the business.
