This often occurs when the minute hand falls off and is repositioned on the square arbor facing in a different direction than it did before.
NOTE: If you are not a clock professional, or familiar with the intricacies of your clock’s mechanism, we recommend calling Clock Repair Studio for professional service.
The solution is to move the hand further around the dial so that the clock may chime once every quarter.
After the hourly striking of the clock, remove the minute hand and place it on the square arbor pointing towards the number “12” on the dial.
