This pretty and unusual Kundo standard 400 day clock has the case parts and movement plates nickel plated. This clock has the unusual square dial. It was made in the early 1950s.

I overhauled the movement. A previous repairer had badly damaged the anchor and escape wheel, so I installed replacement parts, polished the pivots, and installed a new suspension spring and lower suspension block.

5. Schatz Standard 400 Day Clocks – When in Doubt, Replace the Suspension Spring!

The most delicate part of a 400 day clock is the thin wire called the “suspension spring” that holds the pendulum and controls its rotation. On many 400 day clocks, the pendulum can be locked in place for shipping and there is a metal or plastic guard to protect the suspension spring. On earlier clocks, the pendulum needed to be removed for shipping.

Kundo 400 day clocks from the early 1950s have a sliding piece on the guard that secures the bottom of the suspension spring during shipping. The photos below show the guard locked and unlocked, and also show an incorrect guard (a later one) on a clock that needs the earlier guard with the slider.

This Kundo miniature 400 day clock from the 1950s has a case similar to the Schatz “London Coach”. it is 8 1/4 inches tall (including finial). The side panels and rear panel are glass with a molded pattern. The front panel is plain glass.

I cleaned the movement, straightened the hand shaft and replaced the mainspring (the old mainspring had been cleaned in the past without removing it from the barrel and it had corrosion marks). Also, the suspension unit was not quite long enough.

Below are some pictures, there are more on my Picasa web album.

These 2 clocks have large dials with 3 5/8 inch time track (the standard dial has 3 1/4 inch time track). They have attractive skeleton hands. Kundo made both clocks. The left one says “Welby” on the dial and movement.

The left one has the type of pendulum used for many years (it has a slot in the top part of each pendulum arm). The right one has the later type of pendulum without slots in the arms (I wonder if it originally had the earlier type).

The left clock has the longer, earlier type of movement mounting nuts (visible beneath the platform). The right clock has the later type of short mounting nuts.

Kundo used 2 methods to mount the dial to the movement. Earlier dials have taper pins through posts. Later dials have rotating fasteners. The photos below show both types.

Here is a video of these clocks:

I recently repaired this Kundo miniature 400 day clock with a pretty gold colored metal dial. The movement needed cleaning and a new suspension spring. The pivots and pivot holes were in good condition.

Here is a movie of the escapement in operation:
