Abstract :
The world´s first digital electronic quartz watch, the Pulsar P1, was one of the earliest consumer products of the 1970s microelectronics revolution. Manufactured by the Hamilton Watch Company in conjunction with Electro- Data, the first prototype made its public debut on the `Tonight Show?? in the early 1970s. Host Johnny Carson remarked that at $1,500 (the projected price for the initial production models), this would be the watch that would tell you the precise moment you went bankrupt.
