This task took more time and effort than it is possible to display using my photos.
During the completion of this task, I have taken apart three clock mechanisms, learned how quartz clocks work and snapped a screwdriver in half.

As I would have no idea where to start making a clock from scratch, I cheated a bit. I used one of those ready-made clock mechanisms.
I decided that, to make my clock less ordinary, I would try to make a change to it. After opening up one of the clock mechanisms, I saw that replacing cogs in an attempt to make one rotation of the hands last 24 hours was not going to be possible.

So I went slightly more basic. Make the clock go backwards. I looked up how to do this and got a few results. However, on attempting them, I found that the important parts of the first mechanism were soldered in place.
I went out a bought a second mechanism, which also failed to provide me with any success.

I was on the point of giving up and just going with a boring forwards clock, when I remembered another clock I had hidden away somewhere. It was worth a try.
After taking apart this clock, I found that it would actually come apart where I wanted it to. I tried the methods suggested on various websites for making the thing go backwards. They didn't work. Getting a little annoyed, I fiddled around inside the clock until I found a way to make the cogs reverse. It was simple, but I cannot come up with any scientific explanation as to why it works.

The problem I then had was mounting the switched metal core in the casing. For this, I needed to drill small holes in the metal to fix to the pegs which held things in place. Luckily, I know my way around the school technology department, and found a cordless drill.

Soon I had holes in the metal and put it back in the clock mechanism. Then I hit the next problem.
It went backwards. Then forwards. Then backwards again. FOR NO REASON! I couldn't (and still can't) work out why. After a bit more bashing and tapping, it would stabilise once set in one direction and not switch.
Anyway, hoping that it would remain stable once pushed in the backwards direction, I moved on to the easy bit. Decoration.
For this part, I decided I would put the numbers going the right way, just to confuse people. Then I wondered what else I could do to make it individual. I thought about putting numbers in seconds instead of hours; 3600 instead of 1 etc. However, what I decided on was even better. Write the numbers in loads of strange ways, so that none of them match. I thought I should also write the numbers as words. But why use one language when you can use twelve? Thanks to German and Latin GCSEs and a much more basic knowledge of French and Spanish, I already knew four foreign languages. I would then use one English word as well. Not being much of a language lover, I had to look the rest up on the Internet. The other languages I have used are Turkish, Chinese, Japanese, Swahili, Polish, Mongolian and Hungarian.
Eventually, after several weeks working on it on and off, mainly spent fiddling with and bashing the clock to try to make it move the right way and not switch direction, I was finished:



I have put it up in my bedroom, where it usefully doesn't tell people the time, and still switches direction every now and then. I tried my best to sort out that problem, but nothing was effective. In the end, I think the random alternate movements just add to the character of my very unique clock.
