This is a 1970s version of the ancient waterwheel clock, a form of clepsydra largely based on a design which has been in existence in East Asia for around 2000 years.
Fascinating to watch, but a rather crude time-keeper!
Heath Robinson mechanics have produced this waterwheel and wooden gearing, whereby the water drips from the top reservoir into the wheel buckets. Once near full, a ratchet is released allowing the waterwheel to advance one segment. The water gathers in the lower brass pool, and is recirculated to the top holding tank by way of a small external pump and copper plumbing to the rear.
More of a kinetic sculpture than a precision timekeeper, but much admired here at Carlton Clocks.
The wooden frame is faced with a brass dial ring engraved with Japanese numerals, and mounted on a slab of veined green marble.
