What is a second? This question seems to be simple. But the answer has kept people busy for centuries. In 1820 a group of French scientists defined the second as 1/86,400 of the mean solar day. Looking at our precision clocks the answer is very easy. One second has passed when the pendulum moved from one extreme to the other. Because we use only the best materials and work with the greatest care, we can promise, that one pendulum oscillation is almost identical with the second of the caesium nuclear clocks. And this will be true for months and years. In addition to production quality our precision clocks need a solid vibration free wall. Sigmund Riefler, the king of precision clocks in the 19th century, knew that microseismic effects disturb pendulum time keeping. By intelligent design and construction, problems like vibration, friction, and changes in barometric pressure and temperature, are avoided. We admit that this has a high price, but one obtains the best accuracy of precision time keeping that is current available in the market. Clock enthusiasts can also admire.
