Westclox Greenwich Electric Alarm
Clock
The Westclox Greenwich electric alarm clock
was introduced in the April 1936 Tick Talk magazine, with a retail
price of $6.95. It is the most expensive Westclox illustrated in the
October 19, 1936 Saturday Evening Post ad. It was discontinued
in July 1939. This clock has the Sangamo self-starting synchronous motor
and a spring driven bell alarm, wound automatically as the clock runs.
Two types of this first model have been observed.
A later model of Greenwich electric alarm clock
was introduced on July 17, 1950.
