I think that this is such a pretty clock that I decided to show it here. The case has glass panels, and the movement is the Kundo miniature (Horolovar back plate no. 1406H). It was made in the 1950s. The case still has it original finish – not bad after about 60 years. When a case is this good, it is best to leave it alone, and not do any polishing.

This Kundo standard size 400 day clock was probably made in the 1960s. It is unusual in having a heavy, cast brass base (most 400 day clock bases are thin brass over a wood, metal or Bakelite core). The fancy dial is in the French style, with imitation enamel numerals applied to the dial). The arch (the piece with the decorative finials above the dial) is made of plastic!

This is a Kundo standard 400 day clock from about 1950 with wide back plate. The name “Kundo” on the dial is written in black instead of red. This may be an early version of the logo (all the ones I remember seeing before have “Kundo” in red).

This Kundo standard-sized 400 day clock has a nickel plated finish instead of the common plain brass. It has a wide-plate movement so I believe it was made on the early 1950s. The back plate has no name, just the Kundo logo in a circle. It uses a 0.0032 inch thick suspension spring. I didn’t do a full repair on this clock – just replaced the suspension spring. The gears are not nickel plated.

5. Kundo Standard 400 Day Clock

This is one of the most often seen 400 day clocks: the Kundo standard with brass base, glass dome (5 1/2 by 11 inches) and enamel dial. The Kundo is a well-made clock and will last for many years. This one is about 56 years old and still going strong. In the repair process, I polish any pivots that aren’t smooth. The pivot holes in 400 day clocks don’t wear much, so bushings are not necessary. The original mainspring is usually powerful enough to run the clock, but should be replaced if it is “set’ (lost its elasticity).

I polished the base using my polishing machine, then lacquered it. I hand polished the columns and platform after removing the old lacquer. These brass bases sometimes develop stress cracks (see the close-up photo below for a crack in the rear of this base) but they can usually be polished successfully. Some Kundo bases from around 1950 develop long cracks along the edges and may fall apart during polishing.

This clock has a plastic suspension guard to protect the thin suspension spring during shipping. Earlier Kundo clocks have metal guards. This one looks spotted because someone applied solvent to it.

This pretty little Kundo 400 day clock is 8 7/16 inches tall without the dome. The ivory color base and pillars have flowers painted on them. It was made in the 1950s.

The movement is Horolovar back plate no. 1381, and I installed a 0.0024 inch thick Horolovar suspension spring (the 0.0023 inch springs I have now are slightly thinner than 0.0023 inch and make the clock lose time).
