Where might be able to purchase a suspension spring for this clock? It's model is 451-053, top #76
There was no Owner's Guide booklet that came with the clock,
with the following part numbers listed on the back: MONTGOMERY WARD MODEL CPM 9048

on the clock

 made in West Germany

I see where the spring was broken, Thumb screw to replace and I have the Pendulum, was/is there anything else needed to repair this clock,  price shipping and turn around time If available

Edward, there are a few types of suspension springs associated with the Hermle 451 movements, due to different version throughout the years.  I will do some checking Monday at my shop and get back with you.  I can suggest some suppliers and if you have difficulties, I might have the one you need in stock.

I use the smaller suspension springs for the earlier 451 models.  This type had a standard bridge rather than the newer hi-bridge which uses a larger suspension spring.  You can order them from suppliers such as Timesavers, R&M Imports, Black Forest Imports, Merritts Antiques, Mile-High and Ronell. Most of them have On-line catalogs.  I just happen to have a Timesavers  catalog in front of me and their part number for that suspension spring is #24688.   I did not realize that the thumb screws was used in the mid 1970's.  Most of these models used taper pins to secure the suspension springs.  I do have the suspension springs in stock if you have problems obtaining them from the suppliers.  As the suspension springs are rather delicate, I would suggest you purchace two of them, as if one is broken while installing, you have another.  If it is successfull, put the suspension spring in a small envelope and tape it to the inside of the side of the hood near the movement.  Then you have a spare.  If you have trouble getting the clock to run contact me at my shop email address below and I will help you determine what is wrong.

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.
