Perpetual Movement at WIPO

Not to be confused with perpetual motion, "Creators in Perpetual Movement" highlights the evolution of the watch industry and "the ever-increasing importance of intellectual property to that sector." Sponsored by the World Intellectual Property Organization, the exhibition runs from September 24 to October 14, 2005, at the Crowne Plaza Hotel in Geneva. It is open to the public from 10:00 am to 6.00 pm, seven days a week.

Perhaps they will even have one of Cox's timepieces. Though not a perpetual motion machine per se, these clocks are powered by changes in atmospheric pressure via a mercury barometer so as to never need winding. The change of pressure in the Earth's atmosphere kept a mainspring coiled inside the barrel. The original Cox timepeice now resides in the Victoria and Albert Museum of Great Britain.
