This is a Kundo torsion pendulum clock, or torsion clock (also known as 400-day or anniversary clock), is a mechanical clock which keeps time with a mechanism called a torsion pendulum. This is a weighted disk or wheel, often a decorative wheel with 3 or 4 chrome balls on ornate spokes, suspended by a thin wire or ribbon called a torsion spring. The torsion pendulum rotates about the vertical axis of the wire, twisting it, instead of swinging like an ordinary pendulum. The force of the twisting torsion spring reverses the direction of rotation, so the torsion pendulum oscillates slowly, clockwise and counterclockwise. The clock's gears apply a pulse of torque to the top of the torsion spring each rotation to keep the wheel going. The wheel and torsion spring function similarly to a watch's balance wheel and hairspring, as a harmonic oscillator to control the rate of the clock's hands.

I love the movement of torsion clocks - ingenious and fascinating. But more than that I love the face of this clock - it is exquisite! Karen
Hi Karen, you are absolutely correct. I too enjoy these for the same reasons. Many many thanks for the love racer4four! =)
Love it! I saw one recently in a second-hand shop and wanted to buy it. My husband didn’t let me because it was too damaged. Maybe it was a good thing I didn’t because I remember my dad getting one very similar clock (older though) from an aunt and it took a lot of time, effort, and money to find all the broken or missing pieces. But I keep my eyes open and hopefully one day I will find one that works or only needs a bit of repair?
Hallo freiheit, these German 400 day anniversary clocks are starting to fetch top dollar on the collector market. Whenever I find them below $100 I grab them. Many thanks for the love! =)
