Apropos of nothing...old darkroom timer

A friend passed on to me her deceased husband's darkroom equipment. This darkroom timer from 1950-something is just so weird and wonderful that it seemed worth posting a picture of it.

Now THAT is a piece of art. Wow. Thanks for sharing it. Is there more of a story? How does it work?
