I have an Elgin westminster battery operated chime clock and it chimes 10 minutes before the hour. Please help. Thank you.

Question edited for clarity.

How do you Synchronise a Westminster chime clock?
Set the time by moving the big hand forward, pausing at the 11 o'clock position. Listen for the subtle sound of a spring unwinding before moving further. Move the big hand to the 12 o'clock position. Pause and listen for the clock to strike the number of times indicated by the little hand.

Not sure if this will work for you but I had a used one and when I set mine at 12 it would chime 9. So I turned my clock backwards to eleven then ahead to 12. When I did that it chimed 10. I kept back and forth till 12 chimed 12.Then it was reset.

Are there two batteries. One for the time and one for the chime? Try taking the one for the chime out and it should stop chiming. mine worked that way but is a different make.

The Westminster/ Whittington clock means that it has 2 or 3 settings.
1. Silent
2. Westminster Based on the music My redeemer liveth by Handel
3. Whittington
Set the clock onto the westminster setting, this is the easiest. At quarter past the hour it should sound 4 notes. The half past should be 8 notes. Quarter to the hour should be 12 notes and the hour should be 16 notes then the striking of the hour. For example on 8 'O clock you should hear 16 notes then the clock should chime 8 times. Sometimes if the hour is out just gently stop the pendulum, check what hour the clock is striking then without taking the hands off move only the hour hand to the hour. Do not do this with the minute hand.
I hope this helps you! If you are not sure please email me [email protected] I fix these clocks.

Turn the minute hand until the 16 westminster chime operate and then the hour strikes. Remove the minute hand and simple put it back on at the 12 o-clock position. The chimes should now be in sync.

Manually turn the minute hand forward until the 16 westminster chimes sound and then the hour strikes. Then remove the minute hand (it will go on in four positions) and put it back on at the 12 o'clock position. The chimes should now be back into sync.

IF I GATHER CORRECTLY , YOUR CLOCK HAS TWO BATTERIES, ONE AT BASE AND ANOTHER ON THE BACK OF THE UNIT. THE ONE ON THE BACK OF THE UNIT IS RESPONSIBLE FOR CLOCK'S FUNCTIONALITY AND I THINK THE BATTERY AT BASE IS FOR THE ROTATING BALLS ( PENDULUM ). SO OPEN UP THE BACK IF YOU HAVE NOT DONE SO, AND REPLACE THE BATTERY. CAREFULLY THOUH AS THERE RE TWO SCREWS ON TOP AND A SNAP AT CENTER BOTTOM WHICH YOU COULD EASILY BREAK IF YOU DO NOT DO IT WITH CARE. OPEN UP THE SCREWS FIRST AND GENTLY USING A SCREW DRIVER PUSH BACK ON THE SNAP HOLE TO FORCE IT UPWARDS AND INWARDS. IF NONE OF THIS MAKES SENSE THEN WE ARE LOOKING AT TWO DIFFERENT CLOCKS.

HOPE THIS HELPS.

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.
