Clocks, Watches/Willard Patent Banjo Clock


I am looking for information on the movement enclosed in the Willard Patent Banjo Clock my grandfather in law owns. On the back of the movement the following is engraved, "Mason & Sullivan Co., Made in West Germany, No (0) Jewels".  Also inside the clock was a paper that referenced instructions on how to install a "BA90 Movement".  We may need to replace the whole movement due to the fact we think the main spring is the trouble but have not had success yet on the internet or what books we have on hand.  Does this information ring any bells?

Hi, Shawna.  I will check my old Mason and Sullivan catalogs and see if I can cross-reference the M&S BA90.  It might possibly have been made by Hermle with the M&S name on it.  Any additional bits of information would help, particularly a photo of the movement.  Send it to my shop email address below and I will do some checking.  If the movement is still made, it would be a direct replacement.  If the movement is from another manufacturer or not available any more, a substitution would probably require some modifications such as mounting changes and a replacement dial which might be difficult to find.  The best option might be a restoration of the original movement.  But first send the the information and we'll see what we can do.

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.
