Longest Service: Continuous Device Motion

[wolram]

What device (thing with at least one moving part) in constant motion, has given the longest service?

 

[lisab]

You mean with only original parts?

That's a bit ambigeous, would there be maintenance carried out, are worn down and corroded parts replaced? Anyway, these things lasts milleniums:

Yes, an engine that has had say piston rings changed would not count.

No part replacement, may be oiling allowed.

The Salisbury cathedral clock?

The Salisbury Cathedral clock, a large iron-framed clock without a dial located in the aisle of Salisbury Cathedral. The clock dating from about 1386 is the oldest working clock in the world. The clock is one of the group of 14th to 16th century astronomical clocks to be found in the West of England. (See also Wells, Exeter, Ottery St Mary, and Wimborne Minster.) It can be dated to around 1386, and most of the parts are original.

I never knew churches had clocks THAT long ago, great find.

I was going to nominate my mother, but she only dates back to 1912... and she's not always in constant motion.

my mixer belonged to my great grandmother. We laughed when we went to the science museum in Ottawa, and there it was. My dad took it apart and cleaned everything once, but we've never replaced any parts. I am sure its full of lead...

What the hey?! You're a Canuck too?

On Mythbusters I saw a thing about a light bulb, incandescent, that had been in service in a firehouse for over 100 years, on 24/7...

binzing, I swear you and I have resonant brain waves sometimes. I had this same thought, but since there are no moving parts I didn't post it.

The filament vibrates, therefor, it moves.

My and my roommate had a small floor fan running 24/7 all last school year. It still works to this day.

Gawd, the Canuckerites are invading, watch out guys or we will all be eating peanut butter on horse back.

I'd vote for the Solar System - sun, planets, moons. Continuous motion, as far as we know, since before humanity, something on the order of 4-5 billion years. And no lubrication or adjustments required.

Before the solar system would be the galaxy in which we are located - billions of years older.

One did not specify if the device was natural or not.
