Seiko DATA-2000 - The First "Smartwatch" (1983-1984)

✅ Seiko DATA-2000

🥇First Commercially-Released "Smartwatch" 

The Seiko DATA-2000, released in 1983 for around $295 (roughly $940 today), is widely considered the world's first true smartwatch. While other digital watches of the era offered basic, tiny calculators, the DATA-2000 was a wrist-mounted organizer capable of storing 2,000 characters of text—enough for a substantial contact list or a full day's worth of memos. Its most striking feature was its external keyboard dock; because the watch itself lacked enough physical buttons to type out words, users had to snap the watch into a magnetic cradle on a companion keyboard, which transmitted data wirelessly using magnetic pulses. This pocket-sized "wrist computer" featured a miniature processor and a dot-matrix screen that allowed it to display actual letters and words rather than just blocky digital numbers, serving as a fascinating early ancestor to wearable tech.
