The Casio CD-40 is a legendary piece of wearable tech history, celebrated as Casio's very first Data Bank watch.
Released in 1983, it pioneered the concept of carrying personal data on your wrist.
Key Features & Innovations
- The First "Data Bank": The defining feature was its "Telememo" memory function, which allowed users to store telephone numbers and short text notes directly on the watch.
- 24-Button Keypad: It featured a prominent front-facing matrix of buttons used to input numbers and letters, doubling as a fully functional 16-key calculator.
- Core Functions: Beyond its computing and storage capabilities, it included digital mainstays like a stopwatch, daily alarm, hourly chime, and a calendar.
- Design Aesthetic: Built primarily with a resin case and a chrome-look or black finish, it was paired with either a resin strap or a flexible steel bracelet depending on the regional variant.
