A trade name for the Kieninger and Obergfell Company, Kundo is almost run like a different company. The name was spanned using the first letters of the names of the manufacturers K for Kieninger and then ‘und’ meaning and, and O for Obergfell. The name was reengineered in 1918 and used for the production of all types of clocks including the anniversary (400 day) clocks from 1923. These are what they are generally known for, and although they launched an electric clock later in their career, the anniversary clock is the item that has stuck with individuals and become the popular Kundo Clock item.
The Kundo clock comes in many different types and models, and many individuals like how they run silently and dependably. One of the beautiful things about the Kundo clock is that it only needs to be set every one or two weeks and whenever they run down, which is usually between 9 and 13 months. The Kundo clock has always made a great gift for any individual who is interested in clocks and antique items. Most clocks run from one to eight days within winding which means that the 400 day anniversary Kundo clocks run even longer. Because a torsion pendulum is used, it allows the clock to run differently. The torsion pendulum uses a thin wire that rotates in one direction and then the other instead of swinging back and forth.
It is this unique design that makes the pendulum have to swing less in order to keep time and allows the Kundo clock to run for about 400 days. By having more gears than the 8 day clock, the mainspring is also designed to unwind much more slowly on the 400 day clock as well. The large versions of the 400 day Kundo clock are around 12” tall. The miniature 400 day clock are built with the same dynamics as their larger counterparts, but they use smaller gears and making them even more energy efficient. Where larger Kundo clocks make about 8 rotations a minute, the smaller Kundo clocks make about 10 per minute.
