I thought about putting this in trading, but since I don't plan to sell either of these, here's the best place.
The name of these mechanical alarm clocks with brassy innards is "DEKAD". There was also a laptop table called DAVE, but that's not the point.

That's a swiss army knife for scale. The clocks themselves are three and a half inches, and the movements are one and a half inches by two and a half inches, containing approximately 6 gears, one escape wheel (plastic, dammit) and the balance wheel. And the pallet fork.
For only four pounds a go, you can't afford to miss this most amazing bargain.
dit: Did some wikiin' and found that it uses a pin-lever escapement.
