Nothing wrong with form, if you happen to be amused by the form. Art is always worth exactly what someone is willing to pay for it.
Besides, there's a long tradition of illusion clocks that appear to be perpetual motion or driven by air pressure fluctuation or whatever but are actually disguised traditional movements. So this is arguably better justified than most steampunk assemblages, including some with more "real" function.
If you can really see the actual mechanism, I'm disappointed; it should probably be better disguised.
