Perhaps the earliest digital timepieces were Plato clocks. These spring-wound pieces consisted of a glass cylinder with a column inside, affixed to which were small digital cards with numbers printed on them, which flipped as time passed. The Plato clocks were introduced at the St. Louis World Fair in 1904, produced by Ansonia Clock Company. Eugene Fitch of New York patented the clock design in 1903.So from the 1970s, digital watches and clocks have been in common use.
Josef Pallweber, a Swiss timepiece maker born in Salzburg, Austria, created and produced a mechanic-digital clock model in 1956. The earliest patent for a digital clock was held in the United States by D.E Protzmann and others. Dated October 23, 1956, this patent describes a digital alarm clock. D.E Protzmann and his associates also patented another digital clock in 1970, which was said to use a minimal amount of moving parts. Two side-plates held digital numerals between them, while an electric motor and cam gear outside controlled movement.
In 1970, the first digital wristwatch with an LED display was mass-produced. Called the Pulsar, and produced by the Hamilton Watch Company, this watch was hinted at two years prior when the same company created a prototype digital watch for Kubrick's 2001: A Space Odyssey. Throughout the 1970s, despite the initial hefty cost of digital watches, the popularity of said devices steadily rose.
This is doubtless what prompted Asimov to write an essay on digital clocks for American Airways Magazine. (At one point he wrote a monthly article for their magazine, and when it went bi-weekly, he wrote two articles a month for them.) It was published in the 29 October 1985 issue of the magazine, over 25 years ago.
The article, Dial vs Digital, is available online as a PDF at:
Contrary to Asimov's prediction, however, digital watches have not taken over. While we have digital clocks on our computers, I just did a search on "Watches" at Amazon, and 2/3rds of the results were analog watches - watches with hands and the "clockwise" typeface.
(That was Asimov's main concern - how could we use clockwise and counterclockwise as directional terms, if kids never learned about the clockface. As well as folks who say, "Look over there at 2 o'clock" to find an object.)
