That last part may sound mundane to you now, but this was a game changer in the 70’s.

In the early 80’s, The G-Shock watch was born and the Casio Databank Telememo 10 CD-40 (left), which is a wristwatch that also acts as your pocket Rolodex, meant to store telephone numbers. This eliminated the need to bring a physical organizer, that were quite cumbersome especially when you need to bring a pen or a pencil with you.

The innovations brought by Casio are cornerstones of what makes our smartphones a necessity in life: it’s our timekeeper, calendar, personal organizer, and many more. Modern technology would be very different if companies like Casio didn’t take the chance and create innovative products like the CASIOTRON or the CD-40.
