Info needed for a new pendulum

The floor clock pendulums on this page are for post 1960 mechanical German clock movements only. To get the proper clock pendulum for your clock, you would need the movement numbers off of the back plate of the movement itself. Not off of the paperwork, not off of the wood case, but off of the clockworks itself. Then with this information we can determine the manufacturer of the movement and then also the length the pendulum needs to be. In fact a few things we need, who the manufacturer is, the CM length, how wide the inside of the clock case is so we can get the right bob size.

How to order a new pendulum

The manufacturer for German movements will most likely be one of the four listed below. When you know the manufacturer, you can goto the dropdown list below and select the CM length and bob diameter of the style pendulum you would like. The CM length is stamped on the back plate and represents the length of the pendulum from tip to tip, the leader it hangs on, and the suspension spring that the leader hangs on, all added together in centimeter measurement. Then to figure out the bob diameter, this is the round disk at the bottom of the pendulum and it needs about 2 inches on each side to swing around in the case without bonking the sides of the clock case. This means the actual clock pendulums length itself will be much shorter than this CM measurement.


Clock Pendulums

The Seth Thomas and Mason / Sullivan issue

Issue to solve here is both these manufacturers did not give indication on the ideal length of the pendulum where the movement keeps time on the back plate of the movement. This is true for post 1960 German Seth Thomas and Mason Sullivan as they did not make their own movements pendulums. You would need to follow the link and find out the true manufacturer. So its kind of a process, you need to click the link that says "GoTo Page" below, find the right movement number and CM length and then come back to this page and order the pendulum for the true manufacturer. Or forget all this and just give us a call 800 381 7458 with the numbers you have off of the back plate.

The Urgos issue

The Urgos clock movements also do not give indication of the pendulum length on back plate either. And it gets even trickier as many of the numbers have a new numbering system to replace the old. So here is the process for figuring out the correct pendulum length. First get the numbers off of the clock movements back plate. Then goto the Urgos clock movement page by clicking "GoTo Page" below. Use the drop down order list to see what is the CM length of your movement number. If your number is not there you will need to follow the directions on that same page to convert to the new number and try the dropdown list again to get the CM length. Then finally come back to this page and continue with the ordering of the pendulum.

Large Lyre Pendulum

Lyre Clock Pendulum

The longer metal lyre pendulums with a larger bob, have twisted rods instead of straight. This is the way the pendulum comes if it is ordered for a 94cm and longer PL length is chosen, with a 8.5 and 10.5 bob diameter. In other words, the larger the lyre pendulum the more fancy they are with there design. There are all polished brass style. Center embossing on the pendulum bob is available on some units as well, please inquire via email to clockworks@clockworks.com

To get the proper pendulum for your movement you will need the CM length off of the back plate of the clock movement itself as described above.

Pendulums Complete

Clock Pendulums
  • Metal Lyre
    This is on the left side on the picture. This is a polished brass style grid metal lyre pendulum for 85cm and shorter movement lengths. The longer lengths usually look like the other picture with the twisted rods.
  • Brass Rod
    The brass rod has the top mounting hook and also the threaded bottom with its nut to regulate the timing. The bob with it chosen diameter will go onto the bottom threaded rod and the rating nut under it.
  • Wood Stick
    The wood stick will come unstained. This is so the stick can be stained the proper color to match the clock case. The wood stick pendulum consists of the stick with the hardware and also the bob in the diameter chosen. The good thing about wood stick pendulums is they can be shortened if needed.

Pendulum Bobs / Sticks

Clock Pendulum Bob

A pendulum bob is the round disk at the bottom of the pendulum. The diameter is the measurement from one side to the other. To select the proper bob size you would need to know the inside width of the clock case. You should have at least 2 inches on each side of the pendulum bob so it can swing in the case without hitting the sides. We have some wood sticks available also and there in the drop down list with the bobs. The wood sticks would have to be cut to length depending on your needs, or we have the pendulums complete and assembled with the bob. For this you would need the movement numbers off of the back plate and get a wood stick pendulum complete from below.

Mixed Bobs Clock Pendulums

We offer the above clock pendulums bobs with various patterns. These are for mantle movements with the F-S regulator that you can adjust the timing. This is because there is no rating assembly to adjust the timing.

Item #PD10 - $9

Adjustable Bob Clock Pendulums

This pendulum bob is threaded on the bottom with a rating nut for easy timing of the clock. This can be used on mantle clocks as well as certain wall clocks such as a banjo. Measurement is the diameter of the bob.

Item #PD5 - $13

Grape Leaf Clock Pendulums

Gold tone brass pendulum with leaf decorations on the top of the pendulum bob. Seven inches in length and has a 2 1/2 inch diameter bob that weighs 3.5 ounces. Used with some modern wall and 31 day clocks.

Item #PD28 - $20

Adjustable Pendulum Clock Pendulums

Item #PD22 - $22


Adjustable Mantle Bob Clock Pendulums

This is a 1 5/8 diameter 2.8oz adjustable mantle clock pendulum bob. This is the bob needed if there is no F / S regulator on the front of the clock dial that takes the skinny end of the key. This can be used in place of a F / S regulator as well if finding the right key is not easy. This is on a slider to regulate the time.

Item #PD20 - $9

R + A Style Clock Pendulums

R and A style clock pendulum with a hook top and the rating assembly on the bottom to regulate the time. The R and A stand for Retard or Advance as the time keeping is controlled by the rating nut on the bottom of the bob.

Item #PD44
