Clocks, Watches/Chimes stopped working


I have a "Sligh" mantel clock, 20+ yrs old,model=0,movement=#304-020 Franz Hermle, two(2) jewels.
Recently the chimes stopped working, no chiming at all. So,I removed the min. & hr, hands & the mechanism out of the case and cleaned & oiled (Etsyntha 859). I backed off the springs, off of the striker & chimes, cause I thought they might be to tight. The clock is keeping good time incidentally. Reassembled and wound all (3) spring movements & the chimes are still not working & the clock is maintaining good time. Can you help me out??

Joe, sometimes the numbers are a little difficult to read.  I would think that the model is a 340-020.  It uses a balance wheel for a regulator rather than a pendulum.  A mainspring that is wound all the way will not cause any failure of the running, chiming e or strike.  A clock cannot be wound too tight unless it is forced to the extent that a spring snaps or the key is bent.  The two main causes of a clock not working is due to old lubricant and/or worn parts or adjustments.  The chime function is usually the first to fail.  If there are any worn bushings, the clock has to be disassembled and repaired.  If the problem is due to adjustments, the procedure is rather complicated, mainly to diagnose and adjust.  It would take a few hours of instruction to learn the diagnostic steps and repair for the chime function.  I would suggest having an experienced clockmaker look at it.

As I am not a certified appraiser I do not give values of clocks over the Internet. There is very little published information on what I consider to be the value of "modern production clocks". However, considerations are what the clock originally sold for, the condition of the case and movement, and particularly the area in which you live, the demand and the economy. ALSO, WATCHES ARE NOT MY FIELD. However, I can advise the clock owner on proper maintenance of a clock to keep it running, small corrections and adjustments and how to move a clock without damaging it. I can also advise on obtaining parts for clocks. As clock case model label numbers are difficult to relate to the movements, it is helpful if you can give me the information usually found on the movements themselves. Modern clock movements usually have the information on the back plate of the movement. I have been a clockmaker for about 40 years and was plant engineer in the mid 90's and later operations and engineering consultant at Emperor Clock Company in Fairhope, Alabama. I now have my own clock shop in Prattville, Alabama.


One of my greatest accomplishments was traveling to China to assist a clock factory in building clocks to the standards which we required at Emperor. With the proper specifications and quality control, some beautiful clock cases were built. The factory people from the wood carvers to the plant manager were very congenial, friendly and I left a lot of wonderful friends when I returned from my trips.
