Haruo Suekichi makes watches that look like perverse sex toys and/or Saw props. He recounts his initial inspiration in an interview with Chief Magazine:

“In the beginning, they were pretty simple, a strange drawing maybe, but that’s about it. But at the flea market, a one-armed man came up to me. And he said to me, well, with only my left arm, I can’t put on a watch. Wow, I thought, he’s right…I wonder if I could make a watch like that? So I made – and you can see one upstairs in the showcase – I made a watch that you put your wrist in it and it shuts around your wrist.”

I’ve never gotten into the whole steampunk aesthetic but these things look amazing.
