Seiko data 2000 computer watch - The Granddaddy of Smartwatches
Seiko data 2000 computer watch
The Seiko data 2000 computer watch was an early smart watch sold in the early 1980’s that came with a special PDA calculator interface keyboard. I owned one in about 1983 and believe that this was the first watch with a keyboard. It stored quite a lot of information although I do remember it being a pain entering data. However it came in handy for tests at school !!.
So you may have noticed that the watch has a dot matrix display which allows it to display pretty much any character. You can also type in anything you fancy for storage in the MEMO modes, so it’s like having a ASCII text editor with some extra special characters.
“Always one step ahead of the rest”
Seiko the company
Seiko Holdings Corporation was founded in 1881, when Kintarō Hattori opened a watch and jewelry shop called “K. Hattori” (Hattori Tokeiten) in the Ginza area of Tokyo, Japan. Eleven years later, in 1892, he began to produce clocks under the name Seikosha (Seikōsha), meaning roughly “House of Exquisite Workmanship”. According to Seiko’s official company history, titled A Journey In Time: The Remarkable Story of Seiko (2003), Seiko is a Japanese word meaning “exquisite” or “success” (“exquisite” is usually written from Chinese jīngqiǎo, while the meaning “success” is usually written from Chinese chénggōng).

What does the Seiko Data 2000 do?
Apart from telling the time and fulfilling the traditional chronograph operations, the Data 2000 can also store memos, appointments and perform calculator functions using the accompanying keyboard (model no. UK01-0030).
How does the Seiko Data 2000 work?
This is interesting part: data is transmitted via “electromagnetic coupling”. There’s a small metal loop in the watch and another in the keyboard. Current flows through the loops, turning each into a magnet. Communication occurs via a series of magnetic pulses from each side. Data is transferred (2,048 bits/second with a ~32 KHz carrier frequency) and the watch receives the data for storage.
The watch is placed into the “Transmission Circuit” of the keyboard and the user presses the transmit button on the face of the watch. You can press either the CAL button for calculator mode; M-A for Memo A or M-B for Memo B. There’s also a handy CNT button to adjust the contrast of the watch. Holding the CNT darkens the display; pressing both the SFT and CNT lightens it. The other buttons are intuitive for anyone who’s been around a keyboard.
It was sold in a silver cardboard box with orange trim and included a large instruction book; the watch and keyboard were set in black sponge material. The Data 2000 stores two memos, each with a capacity of 1,000 characters hence the “2000”.
Seiko Data 2000 Price
Seiko’s MSRP on this watch was $295 USD. It was sold in a sleak, silver cardboard box with orange trim and included a large instruction book; the watch and keyboard were set in a sponge material.
The watch requires a BR2325 lithium watch battery; the keyboard uses a CR2016 battery. When you replace the battery, you might need to perform an “All Clear” on the CMOS to get the watch working again.
Take a look for a tiny round hole near the edge of the watch with a gold contact. Take a tweezer or any small metal object and touch this contact and the battery at the same time. Then check the LCD, the display should read 12:00. Is your watch quiet? Perhaps the alarm is disabled. Enable it by pressing the leftmost and rightmost buttons at the same time. Keyboard and watch not communicating? This might be hard to fix, but after inserting fresh batteries, try this: mount the watch in the keyboard and press all four buttons at the same time. While doing this, flip the switch on the keyboard several times.
Where can I get one ?
Although the Seiko Data 2000 is becoming extremely rare we have seen the odd few go up for sale on a well known online auction site over the past few years.
