A hit for 1975 Christmas, with the slogan: "For the man who had everything until just now..." Time Computer Inc. introduced a PULSAR watch-calculator combination with a six digit LED display. The calculator has five functions, plus memory, floating decimal, and display overflow. Originally priced at $3,950, it's designed with around two CMOS chips, one each for time and calculation. The watch uses four battery cells that should last for a year for 25 calculations and 25 under time readouts a day. The drawback to the PULSAR calculator is that users have to use a up in special plastic stylus to key in information. Even though TIME COMPUTER supplies the retractable stylus mounted on the top of a ballpoint pen, the fact that the calculator can't be operated with an ordinary ballpoint tip means the calculator isn't usable if the wearer forgets the stylus.
