Do you understand all the numbers here? Explanation of the numbers is left as an exercise to the reader.
Too complicated for you? How about this one?
Of course, there is an error in it. 3(pi-.14) does not equal 9; but that is close enough.
Can you feel your heart beat faster? Are your hands sweaty? Relax! This is just a clock! This lovely new timepiece appears to have been hand-written by that evil math teacher we all had to endure. Each hour is marked by a simple math problem. Solve it and solve the riddle of time. Or, you can just know that “52 - x2 + x = 10″ happens to live in the “7 o’clock” position and be done with it.
If you don’t like this one, you can get a Pi clock
And a bonus triple 9 clock:
Every hour in this clock is represented by three nines. Care to calculate?
Not sure if I like 7, which is 6.99999999 [Please no "proofs" that .999... is same as 1.0]

What is 90 degrees in radians? With this great clock, trigonometry will be a breeze! Inspired by my math teacher, Ms. Pinocci.

We’ll let you figure out the time on this one.
Below is the Atom 561 clock:
This design marks the 80th anniversary of Atmos clocks by the Swiss maker Jaeger LeCoultre
The power source is a capsule that contains gas and ethyl chloride. When the temperature rises, the gas/chloride mix expands and compresses a spiral spring, whereas when the temperature falls, the gas condenses and loosens up the spring. Somehow that equals a constant winding of the clock, so no human intervention is necessary.

Clock that reveals time in text:
From Christiaan Postima. The starting point with this project was a personal study about form & time. I put together more than 150 individual clockworks and made them work together to become one clock. I show the progress of time by letting the numbers be written in words by the clockworks. Reading clockwise, the time being is visible through a word and readable by the completeness of the word, 12 words from “one” to “twelve”. The size of the clock is 1,4 by 1,4 meter.

Life Clock: not an hour clock, but a clock that tells time in years:
It is a 84 year clock. Source

Planetary orbit clock
little metal planets orbit a larger central planet at the middle of the “universe.” One planet signifies hours, another minutes, and the last tiny planet is the second hand. You can really only tell what time it is by viewing the clock from above, a small price to pay to show off your geek-power. Source Ebay and Gizmodo
