Question
QUESTION: Hello,
   I got this clock from a good friend. After reading other questions and looking at some manuals online, I think I need a pendulum suspension spring. The pendulum hanger has nothing to hook to at the top. Of course it doesn't work right now, but I would like to get it fixed. Could I order one from you or do you know who I should contact?
Thank you for your help,
Pam

ANSWER: Any clock materials house would be able to provide you with a suspension spring.  One you might try is Ronell Clock.  Their on-line catalog may be viewed at <ronellclock.com>  I would suggest you call the firm telling them you need a suspension spring for a Hermle 701-78 with a 55cm pendulum.  I further suggest you order a pendulum spring pin or hanging screw.  I would presume that item was likely missing as well.
As an aside I have never heard of a Hermle 701, nor do I find a listing for one. I am familiar with the 771, the 781 and the 791.  To satisfy my curiosity could you describe the movement.  Such things as plate size, key wind or weight driven, time only, time and strike, time/strike and chime.  I would much appreciate it.  Thank you WJP

QUESTION: Thank you so much for responding! I found this picture on the net. This description is all I know. It looks like this:

There is a screw at the top, but it does look like something is broken off at the base. I know nothing about clocks. It took me hours just to figure out how the pendulum was supposed to hang.

Do you happen to know what the 88,18 means?

Again, my thanks,
Pam

Answer
I am much impressed.  I am amazed that you found the picture you referenced.  After looking it over I surmise the movement is a variant of Hermle's 791 series movement.  The only difference I can discern is that one is spring driven and the other weight driven.  I will contact Hermle for more information and share any pertinence with you.  I don't know what the ,18 means but the 88 refers to the number of beats the pendulum beats per minute.  I appreciate the information you have shared with me.  I shall pursue it as far as I can.  Regards WJP
