What was the first digital watch?

The world's first digital watch was the Hamilton Pulsar Time Computer. It debuted in 1970, and three years later, superspy James Bond donned a Pulsar in Live and Let Die. The timepiece was powered by a quartz movement system and had a built-in sensor that adjusted the brightness of its LED display in response to changing light conditions.
