How to Adjust a Kundo Rectangular Electronic Pendulum Clock
The Kundo rectangular electronic pendulum clocks were produced from the early 1940s to the 1980s. These clocks are usually set on a mantel, since they are so small. Also called 400 Day Anniversary clocks, they need to be wound every nine to 13 months and have the time adjusted every two weeks. They don’t tell time as accurately as modern clocks, but winding them is part of the appeal of an antique clock. Does this Spark an idea?
