The 10,000 year clock.

You walk in and say "CLICK" and the thing sproings over a notch?

If the thing is behind quartz, it would for sure be free of dust unless there were a major earthquake, then all bets are off. Still, 10,000 years is a tad optimistic for any mechanism to run. The mechanism might survive 10,000 years in a protected environment but running, I don't think so. It would probably impress people who would find it 10,000 years from now if there are in fact people on the planet at that time. If there are, and science keeps developing at the rate it is now, the whole planet may become a giant museum, a shrine to the birthplace of mankind. Sorry, I digress.

It can’t ring its chimes for long by itself, or show the time it knows, so it needs human visitors.

Stone and ceramics."

I do not think these are things sonhouse will be impressed by.

Actually, it still sounds impressive if it works. Power comes from temperature differentials from night and day, it is designed with loose tolerances so rust and dust won't kill it. You have to visit it and click on the display to display the correct time.

How accurate that can be in the long term is another story. A thousand years from now, if it is visited and the visitors know it is a clock, it might be off by months, if they still use months in a thousand years.
