The first smartwatch ever created is considered to be the “Seiko RC-1000,” introduced by the Japanese company Seiko in 1984.
This early smartwatch featured a built-in computer and had capabilities such as calculator functions, calendar, alarms, and data storage.
While it may not have had the advanced features we associate with modern smartwatches, it laid the foundation for the development of wearable technology and sparked interest in the concept of a wrist-worn computing device.
