It says,
Rolling ball clock, Santiago
James More French
Royal Exchange, London, about AD 1820
Santiago James More French was one of
several clockmakers to follow an original
design by Sir William Congreve. The steel
ball takes 30 seconds to roll from one end
of the table to the other. At each end a
catch is released, enabling the spring-
driven movement to tip the table the
other way and start the ball rolling back.
The ball travels about 4,000 km a year.

This clock is a work of art, a nice one. I don't think it is truly perpetual... unless somthing is available to rewind it.
The guys who are filming are talking about lots of irrelevant things, and are carrying on a debate whether the clock shows central european or english time, and it looks like they don't know what time is it...
The clock can be seen in the British Museum for free.
