Стырено:
"By 1969 the El-370 Electronic Series was being actively marketed in the USA as “Up to the minute watches for the man who looks to the future”. These watches featured the 3700 series of transistorized balance movements and played a stopgap-role during the period in which the new quartz technology was finding its feet. The EL-370’s lasted until about 1974 when they were replaced by the Elnix series of electronic balance watches"

Судя по ebay - долларов 10, уж очень убит корпус.
