Bulova’s "Accutron" watches, appeared in October 1960. The tuning fork was powered by a one transistor electronic oscillator circuit, so the Accutron qualifies as the first «electronic watch».
Instead of the ticking sound made by mechanical watches, the Accutron had a faint, high pitch hum which came from the vibrating tuning fork. The Accutron was guaranteed to be accurate to a minute per month, or 2 seconds per day, considerably better than mechanical watches of the time.
Bulova made its last tuning fork movement wristwatches in 1977.
* The date code: located on the back of the case, it consists of a letter followed by a number. The letter is the decade (M=1960s, N=1970s) and the number is the specific year within that decade.
