Kundo is a trademark name of Kieninger & Obergfell, a long time German clock manufacturer. Key-wound 400 day clocks, such as this one, are no longer made. They were designed to be wound every 400 or so days, so owners typically wind them once every year on an anniversary date.

How do you speed up or slow down a pendulum clock?

The clock can be made to go faster or slower by means of the nut at the bottom of the pendulum.

Turn the nut only a small amount each time.

The clock’s internal gears energize the torsion spring. It operates on less energy than a conventional pendulum that swings from side to side. Temperature and humidity fluctuations affected the elasticity of the suspension spring in early torsion clocks, making them inaccurate timekeepers.

Anniversary clocks operate with very little energy. Power is transmitted from the mainspring, through the gears to the anchor pin, to the fork, and down the suspension spring to the bottom block, to act on the pendulum with just enough force to keep it moving once set in motion.
