The age of this space-age style clock from Sears is unknown, but its owner, Christie McGann, has had it since the late 1960s.
I’m going by the Sears logo which was in use from 1963 to 1984 and that it is only AM, no FM. Growing up in Sacramento, the first time I ever heard anything on FM radio was in 1969. I know in 1973 I had a Sears clock radio that had both AM and FM.
Given that Amelia was released in 1965–66 we can guess it was produced in 1966–73.
