This handsome device from 80 years ago wasn’t a clock radio. Instead, it was merely a radio clock, namely, a clock and a radio in the same enclosure, both of which operated independently. It is the Belmont Model BRC-571, also known as the Clockette, and it’s shown here in the January 1940 issue of Radio Today.
The set tuned 540-1720 kHz, meaning that it would pull in police calls in addition to standard broadcast stations. The clock was described as self-starting, and the radio was a standard 5-tube superhet, both of which were housed in a walnut cabinet.
You can see a nicely preserved example of the set at the Radio Attic Archives.
