What was a "Data Bank"?
Casio's Data Bank watches were essentially miniature electronic organizers worn on the wrist. Depending on the model, they could store information such as:
- Telephone numbers
- Names and contacts
- Notes
- Alarms
- Calendar information
- Calculator functions on later models
The concept was revolutionary for the early 1980s because digital memory was becoming small enough to put inside a wristwatch.
The famous Data Bank 676
A particularly collectible later model is the Casio Data Bank 676 / DBC-61, which appeared in the 1980s. Unlike the earliest Data Bank watches, the DBC-61 combined a calculator keypad with telephone-number storage, making it one of the classic "computer watches" of the period.
