In 1984, Seiko released the UC-2000, a smartwatch. Grand Seiko Watches also included a complete QWERTY keyboard, albeit one that was connected to the wrist computer via a dock. In theory, it might still be worn; a bigger version was confined to a desk.
Functions
In addition to telling the time and date, the watch, like the majority of digital watches from the era, can also be used as an alarm clock and stopwatch. However, it transforms into a “Wrist Information System” with the UC-2100 keyboard attached, which can plan appointments, hold memos, and function as a calculator. The UC-2000 model designation comes from the ability to store up to two memos with a character count of 1000 each.
The UC-2000 appears to be extremely advanced for its time and completely archaic in comparison. It had two kilobytes of RAM, six kilobytes of ROM, and a 4-bit CPU. A straightforward 10×4 character LCD with a rectangular form factor and four buttons at the bottom was used for display. It was designed to be used with the UC-2100 dock and was branded as a “personal information processor.” When paired with the UC-2000, this added a full physical QWERTY keyboard that interacted with it. As an alternative, you may choose the UC-2200, which included a thermal printer in addition to a keyboard. Oh, also ROM packs for games, like a translator from English to Japanese, or Microsoft Basic.
How could you handle this?
It was a simple watch, so it could tell the time and also served as a stopwatch and alarm, naturally. However, it could also be used to make appointments, perform simple arithmetic, and save two memos of up to 1000 characters each.
Connectivity was the one thing this smartwatch lacked. It was unable to access the Internet or retrieve data from the ether through radio or any other means. It wouldn’t even quite qualify as a smartwatch by today’s standards. more so, a wrist-mounted personal organizer. Nevertheless, this device was essentially an entire computer that fit on your wrist at the time.
