FS: Vintage 1983 Seiko Data-2000 Computer Watch. New old stock. Complete package with even the outer box. Comes with watch, keyboard, hang tag, oversized manual (small crease on top right corner of front page), covers, original batteries (dead) and aformentioned outer box (worn). Never been used, purchased and stored since the 80's. Contacts clean, batteries never leaked (see pictures).
Aside from telling time and fulfilling the traditional chronograph duties, the Data 2000 can also store memos, appointments and perform calculator functions using the accompanying keyboard (model no. UK01-0030).
How does it 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. (Pocketcalculatorshow.com)
Asking $415 Via EMT. Includes shipping. Ships from Burnaby, BC, Canada. FTF welcomed as well. PM with any questions. Thanks.
