Your clock is commonly known as an anniversary clock. They are also called 400-day clocks. The names come from the fact that they only need winding once per year.
The missing spring on your clock is called a suspension spring and is made of a thin, flat metal, not silk. If someone put in anything other than a true 400-day metal suspension spring in your clock, sized exactly to your particular model, the clock will not run.
Both the spring and dome can be replaced if you ever want to get your clock in running condition again.

Hi Bill:
Thank you so much for the info. No, I did not know what I purchased but read somewhere that a silk thread was used and assumed that must be what I have, but in closer inspection, it appears like it is a very thin copper color.
Do you have any idea of value?
Thank you.
Clock value by: Bill
Clocks of this type in good condition bring between $80 - $150 on eBay. Slightly higher prices in the antique stores.

Hi: Thank you very much for your input. It is about what I have been quoted in the area. So I feel pretty good about that. Thanks, again. K
Socol Montag and Co. by: Anonymous
While not the same clock, my 400-day, anniversary clock has the same face. Mine is porcelain. From looking on the internet, I've concluded mine was manufactured by Socol Montag and Co. in Germany, ca. 1930. There is an auction company, Roschmi, that has mine shown for sale. (I must have over-paid for mine, but mine is in perfect condition.) I hope this helps.
