With the introduction of PCs in the 1980s, Seiko began to develop computers in the form of watches. The firm released the Seiko Data 2000 (in other markets called the Seiko UC 2000 and technically the same, only in different colors) in 1983. It came with an external keyboard for data-entry. Data was synced from the keyboard to the watch via electro-magnetic coupling (wireless docking), an inductive transmission circuitry that allows the communication with a small keyboard (UC-2100), a BASIC computer (UC 2200) and an Apple-II computer.

The name comes from its ability to store 2000 characters. Its memory was tiny, at only 112 digits, and the computer core module consists of a 4bit CPU running at 32kHz, 2 KByte RAM, 7.5KByte ROM. In 1984, the watch was released in black, gold and silver as the Seiko UC 2000.

The Seiko Data 2000 functioned like a miniature wrist-mounted data storage device. To input data, the user set it on a special keypad that transferred your tip-tap-typings to the Data 2000's memory through magnetic pulses. The user could then view the data on the watch's 4x10 character display at any time. It was equipped with a 50×28 pixels monochrome LCD screen. When not docked, the wrist computer was controlled through four buttons, two of which were used to play the basic games which ran on the device.

For it's time, it was a technologically advanced and very sophisticated (and therefore expensive) design. Compared to normal watches, where all the electronics is integrated in one chip, this watch has 6 chips: 5 CMOS and 1 bipolar. Three of them for the display alone. This watch and the subsequent RC series are an interesting insight into the 1980s, when portable computing and watches first came together.
