Clocks, Watches/date of manufacure


QUESTION: my Emperor 'grandmother' clock has the number 385426 on the bottom right of the back of the movement....and a 77 8 76 stamped on the bottom left on the back of the movement...can you tell me when this clock was made?


ANSWER: William, very little is known about the Jauch dates.  I think you are correct in that the clock you have is a "grandmother".  This clock would be about 74" tall and the movement plates are around 6" X 6".  Grandfather movements are around 6" X 9".  Your movement is what we consider the "Jauch 77" and Emperor's designation for that movement was the "100M".  As much as I have worked with Jauch movements and Emperor, I have never been able to confirm the exact numbering system Juach used.  I have seen a few of the grandfather movements with the "77" on them, but that is rare.  I had met with Dr. Heinz Jauch a few times when he was in the Fairhope, Alabama area, but the subject of the "77" or dating was never discussed.  I will ask around and see if I can find anything more specific about the dates.  I am going to make a guess which would be logical but not necessarily correct and that is that the 38526 is a serial number and the 8 76 might have been the month and year the movement was manufactured.  If I find any more information I will post it.

QUESTION: john, thanks for the quick feedback.....we bought the clock, there at the emperor clock showroom in Fairhope, but we don't have any of the paperwork.  our clock stopped working years ago and just decided to get it looked at by a local clock repairman here in the atlanta, ga, area..we've never had it service since we purchased it...he's going to clean/adjust the movement and hopefully get it back's a beautiful piece of furniture and i'm told a solid mahogany clock is hard to find...we're excited about getting it working you know if there is any 'paperwork'...manual,cleaning instructions, brochures available anywhere?

thanks, again for your feedback and i'm looking forward to your confirming the manufacture date, if you can...

William, I do have a bit of information on the "77" (other than the date manufactured).  I know Emperor stopped using the movement in the mid-1980"s because of a wear issue.  Clockmakers will often reject the restoring jobs because of the excessive wear.  As an option we install a Hermle movement using a conversion kit designed for this replacement.  I do have installation, maintenance and troubleshooting manuals for the Jauch 77, but is the type of information that can be applied to most modern production movements.  If you will contact me at my shop email address below, I can give you some more details.

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.
