Clocks, Watches/clock stuck


My grandfather clock will only run when extra pressure is applied to the weights. Its a Howard miller 351-850 movement.

Brant, the 351-850 was made by Hermle for Howard Miller.  If my memory is correct that movement would be for a wall clocks and has a cable drive with 2 weights on the same pulley for the time, and the chime and strike are powered bu mainsprings.  If the movement hasn't been serviced in the last 7 to 10 years, it could be that the lubricants have become gummy.  The clock should be serviced, which involves, cleaning, inspecting for worn parts, repairing anything needed, oiling and adjusting.  Another reason for not running is that it could be out of beat and that would stop the clock.  In beat means that it has an even tick tock, like, tick....tock....tick....tock.  If it goes tick..tock......tick..tock, it is out of beat and that could stop it.  The easiest way to correct that is to move the bottom of the clock to the left or right a little until you obtain an even beat. Try that and if you have any more questions, get back with me.

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.
