Question
Hello,
I need a suspension arm with a adjusting screw & a pendulum stick both for model 451-053.
Any help would be appreciated.
Thank you,
Lloyd

Answer
Okay.  First your movement was made by Hermle.  You will need to contact a clock materials house to obtain the parts you need, or you might find it more convenient to contact Hermle direct.  I recommend a regional parts provider.
There is more information on the movements brass backplate that you will have to provide the vendor.  Stamped below the 451-053 impressed on your backplate are two sets of numbers separated by a line, the top one provides pendulum length in centimeters, probably 94cm,, and the lower, the number of beats per minute, my guess 66.00.  This is essential information in acquiring the correct parts.  This should do it for you.  Regards WJP
