After spot cleaning mantle clock with German movement (circa 1960), the clock chimes properly on the hour but does not chime on the half hour.

They should chime on the quarter hours, but it should be a short chime. Some help in the link, but it probably needs servicing.

when it chimes, spin the hands in clockwise direction to match what chimed.

Standard mechanical clocks were often equipped with a lever to switch off the chimes when "silence" was needed, such as during the night when people were sleeping.

It is also worth noting, with a mechanical striking/chiming clock, that it is very bad practice to set the hands to the correct time by moving them backwards and doing so can really upset the mechanism of some clocks and the services of an horologist can be needed to restore them to fully working order.

To set the time an hour back for instance, the hands should be advanced eleven hours, pausing at each quarter, half and hour to allow the full chime before advancing. Stopping the clock and waiting for the correct time to come around is a suitable alternative if the mechanism is accessible.

Hello Shirley Petty,

Because you specified no movement name,
make or model...

I'm going to assign myself the simplest movement
on this precious little planet...

Solution:
REPOSITION those HANDs to match
the chime strokes.

Get it to chime then loosen minute hand then move hand back to the 12 or 6 position tighten minute hand and test to see if that works

In a quartz movement clock, with a problem like this, the chime box (or whole movement) will need to be replaced. Timesavers.con carries a large selection of chiming quarts movements.

The next time it chimes multiple times turn the hour hand clockwise until it is pointing at the number of times it gonged. Next take off the dial nut off (make sure to put it in a plastic bag because they can be hard to replace) and turn the minute hand until it chimes signaling 15 minutes after. Now put the minute hand back on pointing to 3 o'clock and replace your dial nut and you are all set.

Fix Clock That Gongs Wrong

I suspect that the mechanism needs cleaning.

Take a look inside and if there is the slightest sign of dirt (particularly on the striking mechanism) then it should behave properly after cleaning.

You were not very specific about you clock description, Many of the German clocks were using auto correct features.

You may not have this function.

Move the hour hand to the correct hour.

Hope this tip help you.

This clock does not adjust that way.

Hope this tip helps.
