Pulsar was originally the brand established by Hamilton for the first digital watch. The brand is now owned by Seiko, and is positioned below Seiko, but above Lorus. Pulsar watches are most commonly analog. They generally use the same movements as the lower-end Seikos such as the 7T62 quartz chronograph movement.
Digital watches were very expensive and out of reach to the common consumer up until 1975, when Texas Instruments started to mass produce LED watches inside a plastic case. These watches, which first retailed for only $20, and then $10 in 1976, saw Pulsar lose $6 million and the brand sold to competitors twice in only a year, eventually becoming a subsidiary of Seiko and going back to making only analogue quartz watches.
