BTW, have you read the book Longitude by Dava Sobel? It chronicles the struggles of John Harrison (the inventor of the grasshopper escapement) to produce a shipboard chronometer accurate enough to be used for computing the ship's longitude.
Clock and watch movements are fascinating, indeed. One that particularly captures my fancy is the tourbillon watch movement, a sort of planetary escapement:
I love clocks. This month, I'm driving cross country round trip in 7 days, mainly to move two clocks from my parent's house in SC out to LA. ~800 miles per day 3 days in a row each way, just one day there. One grandmother clock I built them from a kit (Emperor Clock Company, circa 1980) and a neat old german mantle clock.
The grandmother clock was the main reason for this Cannonball Run, there was no shipping option that was cost effective. Ridiculous.
But as a bonus, I fill the car with lots of other neat little stuff (just me, no passengers). I get old tools and Dad's electronic treasures, including an IMSAI 8080 computer and stuff from SWTPC. He was into computers LONG ago. Also a bunch of Heathkits (Logic IC tester, etc).
Anybody need any unopened 286/386/486 software from the early 90's? Dad was quite the hoarder. Dunno where he got it from!

That's the price for all-mechanical! That rotary vernier dial IS da bomb.

Also, here's a video illustrating one man's passion for handcrafting watch cases:
There's also a more detailed video with sound, but I was not able to find it on the 'net anymore.

I always wanted a nice old gold "repeater", a chiming pocket watch. All mechanical. http://en.wikipedia.org/wiki/Repeater_(horology)
Never gonna happen.

And the mechanics is probably much less than the LEDs.
Cool way to show the John_Harrison escapement as a grasshopper as that was what Harrison called it.
