Utilizing the UW01 module, you could also store 2000 characters on board, as well as perform the time/date, stopwatch, alarm and hourly chime functions.

According to Steve Fisher, “The watch (UC-2000) had a metal strap with grey aluminium fascia and grey/orange buttons. As stated before, it was a bit clunky but did its job very well. The watch had a 4×10 (50×28 total resolution) block dot matrix style LCD display.”

If any device was ahead of its time in 1984, it would be this watch. By 1986, merchandise liquidators, like Damark, were selling the entire Seiko system for approximately $100. In Japan, the UC-2000 was offered a la carte, as one could purchase the watch (Y19,000), terminal (Y29,800), ROM packs or any combination of each.
