Clocks, Watches/Emperor movement 100M


Hello John, I saw an old question/answer from 2006 regarding the subject movement where you said this movement could replaced with a Hermle 451-050 I'm movement.  You went on to say other parts would be needed to make this change, and that, if the old movement was sent to you, you could do the re-build and return it ready to install.  If you are still in the repair business, and all parts are available, how much would if cost to perform the repair as described?  Thanks.

Mike, there is a conversion kit used to replace the Emperor 100M (Jauch 77) with a 101M (Hermle 451).  This includes all parts needed for the conversion.  I have the kits that use the original dial, weight shells, pendulum and, gong assembly.  There are other kits available that replace the dial (moving moon dial), a wooden stick pendulum with bob, polished weight shells and fillings, gong assembly, hands and hardware.

I send conversion instructions I have written with my conversion kits, but if you don't feel comfortable with doing it yourself, I send instructions for removing the complete assembly and sending the movement, dial and movement/dial frame (all still assembled), and I will do the conversion for you.  Either way, you have to realign the chime and strike hammers after installing the assembly back in the clock.

Understand that I am here as an Allexperts volunteer, to offer advice and not provide a repair service or parts sales.  However, if hard to find parts are not available elsewhere, I do offer them if we have exhausted other sources.  If you are interested in a conversion kit, I can do some checking and see who presently has them.  With my kits I do offer phone and email support for the conversion.  I am familiar with the process, as I was plant engineer at Emperor and helped write the conversion kit article for the American Watch and Clockmakers Institute's publication, "Horological Times".  If you would like further details, you can contact me at my shop email address below.

Note concerning questions not related to Allexperts:  Because of my commitment to answering Allexperts questions within a prescribed time limit and the large backlog of clock work at my shop, I regret that I cannot answer personal email questions on a timely basis, other than Allexperts follow up questions.  I will try to answer these emails as soon as I can. Thank you for your patience.

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.
