My clock chimes the correct amount of chimes on all hours except 7. At 7 it chimes 5 times

Source: Wikipedia

The full hour chime is followed by one strike for the number of the hour by Big Ben (E3) (one strike for one o'clock, two strikes for two o'clock, and so on). ... The mechanism then plays two complete sets of five sequences for each complete hour.

Learn how to fix a mantel clock that chimes at the wrong hour. This simple fix will repair a clock that chimes at the wrong time. This can commonly occur when your mantel clock is laid down on its back and the timing is offset.

1 Thing You Have to Understand First On most clocks you can turn the minute hand counter-clockwise but SOME clocks are not safe to be turned in that direction. For this reason, it's best to only turn your minute hand clockwise just to be safe.

The Simple Mantel Clock Adjustment The easiest way to adjust a mantel clock chime is to move the hour hand to the hour that the chime is striking. Make sure that the hour hand shaft is not too tight or else it will not turn. Most mantel clock hands are friction held. DO NOT BEND YOUR HOUR HAND, loosen the shaft if it will not turn freely.
Once you have synchronized the hour hand with the hourly chime, adjust the minute hand to set the clock to the correct time by moving it forward (clockwise) around the clock face. Allow the chime to strike at every quarter hour strike.
Mantel clock Chime Adjustment When your mantel clock chimes the wrong number of times, your chime is not synchronized time of the clock. To adjust your mantel clock chime, proceed with the following step:

ADJUSTING THE HOURLY CHIME

1. When your mantel clock chimes, count the number of times it chimes. This is what time your hourly striker is set to.
2. Move the hour hand to the hour indicated by the hourly chime (count the number of gongs at the hour).
3. Reset the time using the minute hand to the correct hour and the chime should adjust along with the clock hands as well.

ADJUSTING THE QUARTER CHIME

On most mantel clocks, you can simple remove the minute hand which is friction fit. You have to apply pressure on the tube and it will loosen. Once removed, re-install the minute hand at the correct time. From there you can rotate the minute hand to reset the time.

The clock probably thinks its night / early morning so it stopped chiming on the quarter hour. Move the clock forward 12 hours. It should correct itself to think its day time instead of morning.

With our old clock when the chimes got off, we would advance the clock hands 3 hours while NOT allowing the clock to chime any of the hours or half-hours.

whenever the battery is weak the chime changes....whenever you change battery the clock chimes to the last time it chimed so...try setting your clock to next hour of chime n then move the hands of clock to next hour n your clock will chime accordingly.....
in this way waiting for chime to finish ...set to clock to present time ....waiting for it to chime every time the minute hand passes 12

The next time it gongs 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 strikes once. Now put the minute hand back on pointing to 6 o'clock and replace your dial nut and you are all set.

Fix Clock That Gongs Wrong

Count the number of times the clock strikes, while leaving the minute hand pointing at the twelve, move the hour hand ( short hand) to the number it struck. ( this is the only time you should ever move the hour hand yourself). Tighten the hour hand by pressing the hour hand in towards the dial just a little. This can be done by placing a thumb nail on each side of the base of the hour hand at the center shaft. You do not want the hand to touch the dial. Now run your clock up to a quarter after, and let it chime. Now the half hour, the third quarter, and finally the hour. It should strike the correct hour if done correctly. Short version, move minute hand(long hand) to twelve so that it's pointing straight up. 2 move hour hand(short hand) back one hour. 3 tighten hour hand by pushing in toward dial. 4 check the function by advancing the clock one quarter hour at a time letting it chime in between quarters, then counting the strike on the hour. Hope this helps, and not confuses. Good Luck

When you are setting your clock, when you go pass the hour you have to let the clock chime completely, if you do not do this you can damage the time sequence..You have to reset the chime cable or belt...but anytime you set your clock when you get to hour let it chime completely before continuing on...Try also going around with hour hand onetime and let it chime, if it will chime at all, if not you can get a manual download online. Clocks like yours has websites and support who can help you...I think it just needs the chimes reset.

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.

Take the batteries out from the base, where the chime mechanism is. Wait till it gets close (20 seconds till) to a specific hour time, like 8:00 or 9:00, replace the batteries for the chime mechanism. And then count the chimes at the hour. If they are correct, you are set. If they are incorrect, turn the time back 15 minutes before the hour and bring it right back and monitor the chimes again. Hopefully this should fix it. Please post the results.

If you manually set the time, the chimes will be off unless you wait for the chiming to finish before continuing to turn the hands.
