Clocks, Watches/Emperor Clock


I have a Grandfather clock I purchased around 1972.  It has stopped running and nothing I do will keep it going.  It has a 100m movement with a 77 stamped on it.  Is there a replacement for this movement and if so do you have one? I originally assembled the clock and still have the instructions.  Would it be practical to send movement to you for repair?

Thanks for your help.

Phil, as you might have read from some of my answers, the Emperor 100M which we call the Jauch 77 (Manufactured by Jauch of Germany, no longer in business), has had some historical wear problems and the amount of time to restore them for reliable running can be costly.  At Emperor in the mid 1980's we discontinued using the Jauch movements and switched to Hermle.  Some Clockmakers will take the Jauch movements in for restoration, but our shop usually does not.  If you will reply to my clock shop email address below, I will give you some details on the replacement of the Jauch 77.  The Allexperts forum is for advice and not sales.  But I do provide parts, etc., when there are no other sources of parts or procedures available.  I do have the Jauch 77 conversion kits, but I will also give you some other sources and let you decide how to proceed.

Due to the number of Allexperts questions and
the workload I have at my clock shop, I regret
that I cannot answer personal email questions
on a timely basis other than Allexperts follow

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.
