Dad had a clock/pen holder like this. I'm pretty sure it was exactly like this with green hands (they probably glowed in the dark). He kept it on the dresser in the bedroom.
The first clock radio I ever saw was one like this. It was white and rather than having light-up numbers, the numbers were on little plastic pieces that flipped over every minute/hour. My older sister owned it and of course I wanted one like it. By the time I was old enough to get my own clock radio these were out of style and the new ones were out.
I didn't have one of these but I remember when they came out in the 80's. I was in high school and math teachers sometimes had to confiscate people's watches along with their calculators during exams.
My parents had a clock like this, for years it sat on their bedroom dresser. But when Dad redid the living room it was placed on a shelf there. They never wound it and I never saw it work.
