This concept design for a Cheshire Cat pocket watch tells the time by the disappearing bits of the mad kitty.
The hours are affixed around the outside of the case in normal clockwise fashion. The cat himself is segmented into 5 minute intervals, the grin, appearing first, is 5 minutes, his head is the 10 minute mark, and each stripe is five minutes. The singular minutes are four dots affixed just below and between the 12 and 1 hour markers.
`Oh, you can't help that,' said the Cat: `we're all mad here. I'm mad. You're mad.'
`How do you know I'm mad?' said Alice.
`You must be,' said the Cat, `or you wouldn't have come here.'
