Seiko Vibron Tuning Fork Clock c1960s-70s

Image
Significance A Seiko clock using a tuning fork and mechanical movement, powered by a battery and single transistor drive. Made in Japan in the 1960s to early 70s in the brief period after transistors became available and before they were replaced by quartz clocks. Description The Seiko Vibron VBZ-208 is an electronic-mechanical, 6-jewel clock that uses a 150 Hz vibration, H-shaped, double-ended tuning fork. The tuning fork element was developed by Seiko to be virtually immune to changes in temperature being made of a special alloy. A single transistor switch drives a solenoid to magnetically excite the tuning fork. The other end of the tuning fork has two magnets, along with a rotating disk that constitutes a synchronous motor that then drives the gears set to the hands. The movement offers extremely high timekeeping precision. The clock is big and heavy, around 2 kg, indicating it was probably quite expensive when new. The face is metal rather than plas...

Bulle battery electro-mechanical pendulum clock

Image
Significance A pendulum clock that doesn't need winding, just its battery replaced each year. Reasonably accurate because of a pendulum when adjusted carefully. Uses the then-new electricity in the 1920s. Super cute too! Shows the workings of the mechanism. Description Electro-mechanical. Battery powered, 1.5 V cell. Electromagnetic pulse to keep pendulum working. The coil is on the pendulum which moves in an arc over a rod that is permanently magnetised. The pulse is triggered so that opposite magnetic poles attract and like repel. The impulse is probably more gentle than that from a spring-escapement mechanism. Glass case pendulum desirable to see mechanism working. Are expensive when restored. Made in France 1920s - 1950s, approx 300,000 made. Bought on eBay after another sniper shootout early in the morning, the item from Spain.   My Belle clock, glass on all sides to show movement. Restored when bought. The dial is in very good ...

Suko Artempo Handless Clock c1990

Image
Significance Modern quartz clocks can be cute too! A novelty clock. Suko made a number of similar designs using the same principal. Description A novel design. Italian I think. The dial rotates around the spindle with the time indicated at the spindle. I think the white "hands" have been added as they are not on other clocks. A year 2000 clock is available but I have yet to get one. Source Ebay, Melbourne, Australia.
