Actually, early clocks only had an hour hand. It was really all you needed back in the slower-moving days of yore, and you didn’t quite have the precision to have an accurate minute hand anyway.
Hmm… Standard clock mechanism, lose the hour dial, take the hand off the minute dial, weld small cog to it, and adapt a bike chain. Looks like I’ve got a little project this weekend…
Alternatively, where can I just buy one? Now!
Pretty easy to set the correct amount of distance for the hours, too. Number of teeth on wheel = number of links for one hour.
I’d be tempted to use a smaller chain and mechanism, myself, but if you’ve got a nice solid clock mechanism you’re not doing anything with, go for the bike chain.
Think about it though…. in a conventional clock, the numbers are stationary, and the hands move clockwise around it. With this one, the hand stays stationary at the 12 o’clock position, and the numbers move past. However since the gear moves clockwise like a conventional clock, the numbers have to be placed in reverse so that they count up correctly. All you would have to do is place an identical secondary gear next to the initial, and run the sprocket off that one. That would reverse the directional rotation, allowing the numbers to rotate in the more logical left-to-right sequence we are used to. However, evidently the manufacturer didn’t feel the need to do so with this one.
The pointer that denotes the hour always approaches the number from the left-hand side, so naturally I expect the hour number to approach the top of the chain from the left-hand side also.
SHUT UP AND TAKE MY MONEY
You spelled “first” wrong.
You know, when you think about it, the simple construction of this clock would have made more sense to be the first kind made.
I can’t imagine it being easier to time 2 hands to swing at different speeds than it is to rotate one chain.

“early clocks only had an hour hand”
…And, all the numbers had a little “ish” printed after them.
early clocks didn’t move, it was called a sundial.
^ LOLOLOL
… for “ish”
Where do i buy this??
People apparently don’t know how to google any more… Here it is and what a bargain for only 2472 $: http://www.unicahome.com/catalog/item.asp?id=47558

If nobody tells me where to get this, are they being a clock block?
I see who you did there…
I clock blocked myself by looking at the price tag. I’d pay $50, no more
Screw that, I’ll get an old bike chain, a cog from a bike, and a clock kit. Ten bucks, tops.
Want!
It’s pretty nifty, and a cool idea…but I guess not really accurate to quickly glance at to see the time.
YOU NEED THA ACCURACY!
WANT.
Honestly, how often do you need to know the exact minute? Heck, when people ask me the time, I often round it anyways, to the nearest 5-15 min.

The ones you can buy run more than the cost of my car *which was cheap for a car, but for a clock?* You’d be better off making it.
It’s a little out of my price range.

“Yours for only $2338″
It feels like the chain is back-to-front. I look at that and want to say it’s ten to eleven, rather than ten past eleven.
So true. It’s a fail not a win.

How do you tell the time??
The pointer that denotes the hour always approaches the number from the left-hand side, so naturally I expect the hour number to approach the top of the chain from the left-hand side also.
they should make one for minutes too (with numbers 1 till 60) and hang it next too it. And while your’re at it why not a 3rd one for seconds?
Clock win. Pricetag fail.
I like how the cog still turns clockwise, but the numbers are in opposite order from a standard clock.
I hate that, I want it the other way around!
If a couple thousand is too much, you can try some other styles for jus a couple hundred instead — http://www.chainclocks.com/
what a bunch of clockheads!
I can’t tell which is cooler the 1970s Atomic Clock! or this!
