Seiko M516 \'Voice Note\' Watch

The Seiko Voice Note is a watch used by at least 3 of the four Ghostbusters. Ray, Egon and Peter are all seen wearing these watches in various behind the scenes shots making it presumably standard for all Ghostbusters. I infer that the point of the Voice Note was to pick up EVPs [Electronic Voice Phenomena] as many paranormal investigators use voice recording technology. The watch was released in 1983 and was produced in low numbers. As with any pioneering technology, the quality was poor but the price was high for its day. Its features include recording either 4 or 8 secs of audio, backlight, MH&Seconds, date, stop watch, etc.
