451-050 and other 451 Hermle Clock Movement's are described in this tab system
Hermle 451 clock movement
Being one of the most produced movement in the clock world, the Clock movement 451 Series is very popular. The 451-050 and the 451-053 are only rivaled by the 340-020 mantle unit for quantity produced. A Hermle 451 Series clock movement will work for 25 - 30 years night and day with out much complaint.
The movement
A grandmother sized clock case would except the Hermle 451 Series clock movement perfectly usually. This clock movement has square outer movement plates that are 120 x 120mm. A chain driven, three weight, Westminster chime clock movement, that fits into tight places.
Pendulum, chimeblock, dail or weights sold separately. Hand nut, chains, suspension spring and leader come with the new Hermle 451 Series clock movement. Chains, leader and suspension spring included. It is basically everything that comes out with the two screws underneath removed. With so many sold, the part and component availability is high for the 451 clock movement, this cannot be said about many other clocks.

About Hermle Clock Movements
Hermle clock movements are among the finest movements made in the modern times. The German made Hermle units typically work night and day for 30 years without much complaint.
To go and get it restored like normally would with any clock after a long time, it is found that is cost is high. This is for good reason as it can be a large task to restore it.
But as seen, since its a modern day unit (Post War German) it can be available new for a very good price.
Get a new movement instead of a fixed up old one, get it in 3 days instead of 6 months. Save hundreds of dollars doing it also.

Movement grades
All the Hermle clock movements Clockworks offers is the best grade. In other words there are a couple styles some units have that are not as good as others. There are various movements that have more than one grade.
Some units can have plastic for the hour hand tube and the next wheel down, instead the better brass. Meanwhile the number is the same for both grades. In other words there is the economy grade and there is the full grade, on some movement series.
Please know that Clockworks will only ship the best grade Hermle clock movements available, every time.

What will be received
Each one of the these fine Hermle clock movements come already oiled, will come with the hand nut also.
If it is a pendulum style clock, it will come with the suspension spring and the pendulum hanger (leader).
If its a weight driven clock, it will come with new chains or cables and with pulleys.
So this will be the movement with its hammer assemble on.
This is the complete movement that comes out of the clock. No weights, pendulum, chime block, hands, dial all this is already present usually.
Upon ordering Hermle Clock Movements
When placing an online order a receipt will be emailed provided the correct email address is entered. If no receipt, please check the spam folder for the receipt from us.
On the receipt is the link to click for the instructions for the product. The Hermle clock movements ships from Huntington, MA 01050 USA and sometimes from other locations also. The movements go out the next business day unless there is something we have to do to it such as a regear.
The Hermle clock movement ships out UPS or sometimes FedEx. Movements rarely ship via USPS unless there is a special request or an international customer.
Hermle Clock Movement Identification
Most important is the identification of the Hermle clock movement and it requires locating the numbers on the back plate of the movement itself.
This can be done by removing access panels, sticking a phone inside and taking a picture, or even a mirror. Use any possible means to get the number of the Hermle clock movement. This information is not in the manual that came with the clock or on the wood case.
On the back plate of the Hermle clock movement there are numbers such as 451-050 94 cm. These numbers indicate everything there is to know about that particular mechanical Hermle clock movement.
Identification is the first step
In order to purchase a new Hermle clock movement, the old number has to match up with the new one. In short, the new movement will be exactly the same.
It is not a knock off. Generally speaking, all of the existing clock components will fit the new movement. Proper identification of the Hermle clock movement is important when troubleshooting, ordering parts, or discussing compatible components.
Thus, when contacting us it is imperative to correctly reference the number on the backplate of the movement. If there is any confusion, send us a picture of the back plate, as close and as clear as possible, and we can help identify which Hermle clock movement is needed.
A new Hermle clock movement is best
To clarify, as previously discussed in several sections, a new Hermle clock movement is always best. A new unit is a fraction of the price of an overhaul.
The clock will be up and running much faster than waiting months for an overhaul to be completed. The new Hermle clock movement will last another 30 years. This is not possible with a restored unit.




Mechanical Clock Movement Wear
Mechanical clock movement wears out after years go by because the oil turns solid. With age, the mechanical clock movement's oil solidifies and becomes black and sticky.
By the time 20 or 30 years go by, the oil has solidified and is creating wear on the brass plates of the movement. So, when this happens, the clock movement will not run correctly.
This is when the movement will need a cleaning at least, or be replaced. Of course, a brand new movement is always the best option.
What wear and where
Look at the old clock movement, and see holes in the brass plates where there are small pivot arbors sticking into these holes. These pivots are what the gears of the clock ride upon and as the pivots spin in the solidified oil, this makes the holes oblong instead of round.
With the pivot holes oblong, the holes are pinching the pivots and creating resistance in the gear train. With the solidified oil and the pinched pivots, the clock will eventually stop working or chiming.
Invisible clock movement wear
This wear takes place in the holes that are in the brass plates and is hard to identify sometimes. These holes in the brass plates become oblong instead of round and this pinches the pivot arbor going into it. Between this, and the solid oil, the clock ceases to function.
To have this repaired is an expensive and long process. To have a mechanical movement serviced can cost two times as much or even three times the amount of the new one.
However, once the movement starts having problems due to the oblong pivot holes, something will need to be done. The clock will never stay running otherwise.
New Clock Movement Benefits
New clock movement benefits far outweigh the benefits of a restoration. This section will explain why that is and what the best course of action is to get your clock working.
Servicing the movement
Clocks need to have fresh oil after 10 years or so. Then, after 20 or 30 years, a full break down of the movement is necessary. This is all well and good and can be done with the old movement.
The movement will run for another 5 or 15 years with no issues but then it will be time to do it again. So obviously this is a new clock movement benefit.
Every time the movement needs to have work done on it or needs bushings, it will last less and less time before it needs attention again. So another new clock movement benefit is that this would not happen.
The repair process is expensive because it takes time to separate the plates, remove all the gears, do the necessary work, and then put them all back together again.
This process may need to be redone if not perfect the first time. The turn around time to complete an overhaul on a clock movement could be anywhere from 1 to 3 months, and in some extreme cases, a year.
It is a slow moving venture that costs twice as much as a new movement would. If a new clock movement is not available, then this is the best, and only, way to handle a clock repair.
Replacing with a new clock movement
If the clock movement is still in production, it is far better to just get the new clock movement. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work.
The new clock movement will be the same one but brand new and ready to run 30 years without much complaint. There is absolutely no way to repair an old clock movement so that it is better than new.
Even the best clockmaker using the best equipment cannot make the clock movement better than a new one.
A new clock movement is a factory fresh restart. The clock will be like it was originally when you first made the purchase from the store. The new clock movement will be made by the same people, with the same machines, and the clock movement is the same.
It is not a close replica or made somewhere else besides Germany. It is the same movement. Not a knock off or replica. So wouldn't it make sense to get the new clock movement instead of chasing the old?
The choice is clear and obvious. The new movement will cost a fraction of the price and the clock is up and running in no time.
Movements That Would Need a Repair or an Overhaul
If a new clock movement is not possible, then a repair is most likely the only option. However we will try to convert it to a new clock movement that is close and easy to adapt.
If it is not an easy one to adapt, or would take too much case work, then the best solution is to have us work on it. Another clock movement to consider having restored instead of replacing it is the tubular bell, which is a high end movement.
The price of a tubular bell new clock movement makes an overhaul more attractive. This is due to the high price on the new clock movements which is over $1600.
Usually the price is less for the new unit but instead these new clock movements are more costly than the overhaul by Clockworks anyway.
We can charge a much lower amount for the complete overhaul on these units. Ultimately the choice is yours. There is a good argument in both directions that makes sense on these expensive new clock movements.
Clockworks = The best repair service
We would love to do the clock movement overhaul here at Clockworks and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only repair clock movements the hard way with no short cuts.
Even with new clock movements, we inspect them and make sure all is well before shipping them out. It is even more important for us to do your repair than another company because we do not go to your house. There is no one being intrusive in your home and possibly damaging your clock case.
The clock movement itself is the only item that gets sent to us. No components need to be sent since we have everything else here such as weights, dials and pendulums. It is a great advantage to have Clockworks work on your clock movement for this fact alone.
A clock supply depot such as us does not need to wait for parts. We possess everything we could possibly need to complete a thorough, professional clock repair right here. If a new clock movement is not possible, then this repair is your best and only option.
The new movement
New clock movement benefits usually do indeed outweigh the repair option. The movement will already have lubrication with clock oil so there is no need to oil it.
The new clock movement comes with cables and pulleys, or chains, the leader, and suspension spring.
This is everything that comes out when you remove the two screws that are under the clock movement, besides the dial and weights.
Once you get the hands and the clock dial out of the way (instructions are sent via email) it's only a matter of removing the two screws from underneath.
The new clock movement can then be put in by someone with experience in 10 or 15 minutes. A person with no experience will take longer, but the point is that it isn't hard to do. This is definitely a new clock movement benefit.
There are some instances where a clock case was made in an annoying way that makes it more difficult, but for clock movements that were in a mass production this is not the situation. This relates more to a few individual clockmakers who's design of the case makes it more tricky to get the new clock movement in or out.
Summary of New Clock Movement Benefits
A new clock movement is typically less than half the cost of an overhaul.
It will also be on its way to the customer instantly instead of months later. A new clock movement will last the longest of any other choice.
Hermle Clock Movement Aliases
Hermle produces clock movements but the use of aliases is quite prevalent. The movement could have a stamp with any name but really it will be made by Hermle.
Some companies bought so many movements that they were able to get their name on the movement instead of Hermle. The following is only a partial list of names that could be on the clock movement.
The best Aliases in Disguise
Seth Thomas and Mason and Sullivan had not only their name, but also their own internal numbering system.
Their stamp and number was on the movement instead of the Hermle number. Since it is not a Hermle number, the number would need to have a conversion to the real number. Correspondingly, this is done with the Mason and Sullivan chart, or the Seth Thomas conversion Chart.
However the Seth Thomas chart is not very accurate, please see instructions on that page.
Best to replace the movement
It is best to replace the clock movement if either of these names are on the movement automatically. Of course, do not have to think and decide if a repair is better, the answer is a simple no. These companies went out of business a long ago and the life of the unit is over.
Ordinarily, the lifetime is 25 - 30 years before it needs an overhaul or replacement. In fact, if ST or Mason Sullivan is on the movement that would indicate the clock is about 40 years old or more.
The other Hermle Clock Movement Aliases are easy
All in all, Hermle Clock Movement Aliases on other clocks use only their name, and not their own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin just look at the number and forget the name.
Additionally, the numbers will indicate what movement it is. If it is a Hermle movement there are 3 or 4 digits then a hyphen, and then 3 more digits. For example, 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.
Other Names Used

- S. Larose
- Mason & Sullivan

Hermle Clock Movement Directory Explanation
Above all, a Hermle Clock Movement Directory is to get to the correct page that contains the clock movement. This is an important first step when ordering a new clock movement.
Thus, Hermle mechanical movements have numbers on the back plate starting with the below few numbers.
Then a dash (-) follows and then some more numbers. For example: 340-020 131-070 1161-853 351-020 and so forth.
So, if the clock says something like 1161-053 drop the second half and click the 1161 button below. Then this will go to the page where the 1161-053 is as well as the rest of the 1161 series.

451 | 461+471 | 1050+1051 |
1151 | 1161 | 1171 |



If Not Listed
If the Hermle clock movement is not found on these pages we may still have it as a conversion or we may be able to create it out of what exists. However, we need to know the movement number.
So please email the movement number. Of course a picture of the back plate is also helpful. Moreover, if the movement numbers do not look like the Hermle movement numbers it may be made by someone else.
Additionally, the mechanical movement identification page will assist with determining who made the clock. In any event, this is for post WW2 modern mechanical clock movements made in Germany only.
451 Hermle Clock Movement
The numbers on the back plate of the 451 Hermle Clock Movement is everything one needs to get a replacement. If the numbers match then the movement matches.
If the clock is a pendulum unit, be sure to select the proper CM length that matches the old unit.

451-053 Hermle Clock Movement
The Hermle clock movement 451-053 is a Westminster Chime unit with 8 hammers on the back. This high quality German movement comes oiled and includes its leader, suspension spring and hand nut.High Bridge or Low Bridge
The 451 and 1151 series clock movements can come in either High Bridge or Low Bridge. The difference between the two is in the height of the post above the movement. The suspension post is the part that sticks out of the back of the clock movement, that the entire pendulum assembly hangs off of. The suspension spring slides into this suspension post, and the leader then hangs off of it. This suspension post on the H series is up in the air by an A frame bracket. The A frame bracket raises the suspension post by around 1 1/4" above the top plate of the movement. Alternatively the low bridge models were not indicated by LB, rather omitted from the number sequence. These have the suspension post more even with the top of the movement, sticking above it by around 1/8 of an inch only.451 Conversion from low to high
These are interchangeable but the timing will be off if going from low bridge to high bridge, and would require a overall pendulum length about 1 1/4 inches less. This is done by cutting the pendulum shorter or getting a shorter leader, either way. The best thing to do if replacing a movement is to get the same one, whether it be the high bridge or low bridge for a direct fit.
Ordering a Hermle Clock Movement
To order a Hermle clock movement we need the numbers off of the back plate of the movement itself. Match the numbers up so the new movement will be exactly the same as the old one.
Replacing the movement is a fraction of the price of a repair. It is also the fastest way to get the clock up and running again.

Clock movement removal and installation
Removing and installing the clock movement requires the most basic tools. All of the Hermle clock movements are in stock and ship immediately. We are full time clock makers and retailers.
This means we can help from start to finish. If needing assistance in picking out the correct Hermle clock movement, installation or troubleshooting, we can help. Please do not hesitate to ask.

Matching the CM when ordering a Hermle Clock Movement
This note only applies if the current Hermle clock movement has a pendulum. Please match up the CM length from the back plate of the old unit to the new one.
The options in the drop down menu ultimately indicate stock items that are available. However, if there is a CM number that is needed and is not listed, we can usually create it by changing some gears. If this is the situation please give us a call.
There is an extra fee for regearing the movement. Usually this is an additional fee of $100.

Conclusion
Replacing a clock movement is less costly than an overhaul. The movement will last another 25 years before needing any work. Since it is still in production, and offered at a very reasonable price, it makes sense to replace the movement. The clock will be problem free right away, instead of months.
Plus it will inevitably last longer than an even the best overhaul. There is no way to restore better than a brand new movement. So please make the wise decision of replacing whenever possible.

Good afternoon I have a question for you I have two Ridgeway grandfather clocks one of the movements is 451- 053h and has a high tension spring the other is 451- 053 and has a low tension spring what are the costs for both of these movements
Cost is the same either way, high bridge or low bridge, currently at $375. Comes with chains / leader / hand nut / suspension spring, it already oiled and ready to go. Comes with instructions and support if needed.

Thank you. I greatly appreciate your help.
Hi James,
I have the following 1969 Hermle Black Forest Clocks pendulum movement with 3 weights. The info on the movement is 451-053H 85cm 70.777. The pendulum bob is 4.5″. It’s length is 26″ from the double brass hooks on top to the bottom of the bob. The weights are approx. R=6.5lb M=4.8lb L=4.4lb. I need to replace the movement. If I just order the 451-053 Hermle clock movement 85cm high bridge movement ($375) will I be all set?
Yes indeed

Hi,
I have a Hermle 451-053H. I replaced the works about 6 years ago. The Westminster Chime has stopped working. The pendulum works fine and the clock keeps perfect time. And if I lift the lever on the front of the clock the clock will chime the hour but the Westminster Chime will not work. I hate to replace the entire works when the clock is clean and shows no wear on the pivot joints. I know this is a lot to ask but I would appreciate any help you can give me.
Thanks
Steve Lannen
Be sure the clock’s silent lever is in the down position. This lever is at 3oclock on the movement. This is chime ON.
The chain cant be rubbing anything in its path like the seat board. Should be ratchet wheel straight to the weight, not rubbing anything.
Is the hammers hitting anything in its path when they move? If the hammers are rubbing the back of the clock case, or if there hitting or rubbing against each other, the clock will hang up and not chime
The heaviest weight on your right as you face the clock? The chime weight is the heaviest weight out of the three and goes in this position.

Thanks for your reply. I have already checked all the above and all is fine. There does seem to be some resistance when I move the gear to allow the Westminster chime to engage. I have the works just sitting on the board. It would take seconds to pull it out of the clock. Is there anything internally that I should be looking for.
Thanks so much for taking the time to answer my question.

Try clock oil to anything that rubs another, just the tiniest drop. When you see it come out, that is enough oil.

I have ordered clock oil as you suggested. I do have one question. Do the chimes have a spring that wind up as the clock reaches the quarter hour and then is released when the quarter hour hits? If this is true, I feel that this isn’t happening.
Thanks so much,
Steve Lannen
Its called a warning, the spring is wound only ever 8 days, the warning lets the gears spin alittle to get it ready a couple min before the chimes

The heaviest weight would go on your right as you face the clock.
The lightest weight will go on your left as you face the clock.
The middle is light or heavy depending on the bob diameter.
(The larger bob diameters require more weight in the center.)

HI,
My clock is running fast. It started with the correct time, but sped up. Its up to 15 minutes fast now Its a Franz Hermle 451-053 grandmother clock. Any idea what is causing it?
Lower the bob at the bottom of the pendulum with its nut. One full turn is about one minute a day

Author of Clockworks.com
Thank you so much for your quick reply! Husband said he tried that already. Can you think of something else that might be causing it?
I suppose it could be that the escape wheel is worn. If the escape wheel is worn, whenever your not looking it goes tick tick tock tock instead of tick tock, thus time keeping speeds up.
This situation would need the new movement, it would make the most sense financially and also for the longest life.

I have a Seth Thomas Mantle Clock that has a Hermle A403-001 movement. Do you have a replacement Hermle movement and how much would it cost? My clock keeps time but does not chime unless encouraged to chime at the correct time with a nudge on the cam.
Hi,
Is this the balance style clock movement or the pendulum version? They had both under the same ST number

I have a 7G FRANZHERMLE 451-053 U5/cm 70.77 I need to know what weighs to get and pendulum
As for the pendulum, We can help with this but need the CM number – this maybe will be 75cm or 85cm, but this is not right what was put on here =451-053 U5/cm

Hi
Clock needs 1 weight at 4.7LBS and two weights at 6.6LBS from this link if the pendulum bob is 8.5 inch or more.

The heaviest weight would go on your right as you face the clock.
The lightest weight will go on your left as you face the clock.
The middle is light or heavy depending on the bob diameter.
(The larger bob diameters require more weight in the center.)

I have a 451-053 low bridge movement (85cm). I clicked the 85cm low bridge on the order form and a picture of the movement came up showing an A-frame above the movement. My movement has no A-frame. Is the picture wrong?
If the low bridge (no A frame) is ordered, that is what will ship out.

I am so interested in your Hermle 451-053 movement. I have a 47-year-old Colonial of Zeeland grandmother clock with a Franz Hermle movement, “no jewels unadjusted”, 451-053 75CM/75.83. I’ve kept it running with this and that repair throughout the years, but I believe it’s basically worn out chime-wise… I think the time gears are next. It is a low bridge whereas the suspension post is more even with the top of the movement. Would you be able to set me up with a proper, shorter pendulum leader instead of me cutting my original pendulum? Thanks. Arnie Rychlicki, Caledonia, NY. 585 329 2396.
Hi
These are 30 year movements at best. Yours is 47 years old, it is time to get the new one that comes with instructions and support
Please order the 451-053 75cm from this link https://www.clockworks.com/product/new-451-053-clock-movement-by-hermle
It is the same movement as yours but brand new.

HI does this come complete with dial and pendulum
No, movement alone.
Are you looking for the kit version with all the other components ?

Ordered weights online from eBay….A couple bucks! Clock kept good time but the hour strike would stop and go. I think I’ll need a new movement and (2) 6.6 lbs weights; I’ll keep my old 4.7 lbs weight..
Yes the new one is best if the movement is over 20-30 years old. Does it say 451-053 on the back? If so your on the right page. Just match up the CM length to whatever is stamped on the current back plate.

thank-you
What is the CM?
Pendulum length CM stamp is from the top of the movement and all the way down. This is with the lightest pendulum and the smallest bob diameter.
