A Kundo Standard 400 Day Clock That Gave Me Trouble!

This is an ordinary Kundo standard-sized 400 day clock made in the 1950s. Normally, I go through my standard repair process, and the clock works well. This clock didn’t work well after repair. It ran, but the pendulum rotated only about 3 balls (where 4 balls is one full turn), and sometimes it would stop. […]

Kundo Min. 400 Day Clock With Lots of bushings!

My customer sent this clock to me after it had been to 2 other repair shops and still didn’t work. One of the previous shops had done things that shouldn’t be done: The clock had 10 bushings installed. Normally, 400 day clocks don’t need bushings, as they don’t wear much; The escapement (the part that […]
