I have been interested in clocks for awhile, although I do not collect them I do have a fondness for them. I have three clocks that I am very proud of, but I just added a new one to the lineup. It is a Kundo 400 Day Anniversary Clock. I do not know much about these clocks, as far as history goes. But they were made mostly it seems by Kieninger & Obergfell. They are from what was once West Germany. Kieninger & Obergfell made a number of other clocks, but the jewel was the Kundo Anniversary clocks.
The Kundo 400 Day clocks were made first around 1923 or so. I believe the one I have is from around 1950. I purchased it from a clock collector on eBay for $45. The clocks were very popular and even though they are highly collectable, they can be purchased easily for under $100. The clocks were made to be wound one time, and the internal mainspring would rotate a pendulum consisting of four weights (normally in the shape of spheres). The clocks spring would hold a large amount of energy, plus the fact that the rotating pendulum was very energy efficient… the clocks would keep time for approximately 400 days. Most people select a day of importance to be the anniversary of winding. Many people would use New Years or another holiday as the Anniversary, although many would use the the date of purchase for the clock to celebrate.
Often it is hard to find the clocks with the key, as they were often misplaced due to only having to wind it once a year. Also, the directions are often missing, again due to the lack of needing them. The clocks can be repaired as a number of parts are available. Most of the time the suspension spring is in need of replacing.
I have chatted with the previous owner of my clock, at one point he had 10 or so Kundo clocks. He assured me that the clock works fine, and nothing is needed in regards to repair. It does have 2 chips on the 12″ glass dome that covers the clock. But they are inconspicuous and should be easy to hide. The brass on the base is a little worn, but I am ok with that… as the clock is 60+ years old. The clocks also are silent, there is no noise to be heard from them. They are very sensitive to being level. As the pendulum tip is located inside a small brass ‘cup’ – which is to allow for balance (it should be centered within the cup). If it is not level the pendulum will hit the cup and time will not be accurate. In regards to accuracy, these clocks are not always 100% accurate. But if you set them up, and the room it is in stays a set temperature the clock should hold time relatively well. Towards the end of the run time the spring will hold less energy and they tend to slow down a bit.
