Point taken. I would say that there were digital LED
non-portable clocks before there was a digital LED watch.
Can anyone recognize their story about the invention and
marketing of the first LED? Were they talking about the
light-emitting diode itself, or the alphanumeric?
This
http://www.datamath.org/Display/Monsanto.htm points to
Nick Holonyak, Jr. of GE as the inventor of the LED in 1962
and discusses how Monsanto developed the alphanumeric.
Hamilton released the Pulsar LED watch in 1970.
