The first digital watch was the Pulsar, introduced by the Hamilton Watch Company in 1972. The "Pulsar" became a brand name, and would later be acquired by Seiko in 1978. In 1982, a Pulsar watch (NL C01) was released which could store 24 digits, likely making it the first watch with user-programmable memory, or the first "memorybank" watch.
The Hamilton Watch Company was housed on a 13-acre (53,000 m 2) complex in Lancaster. Hamilton took possession of Aurora Watch Company's machinery shortly after incorporation. [citation needed] The first watch made under the Hamilton name was an 18-size 17-jewel pocket watch in 1893.
