Hermle Clock Movement Identification

Identification of a Hermle clock movement is by locating the numbers on the back plate of the movement itself. It will not be in the manual that came with the clock or on the wood case. On the back plate of the clock movement there are numbers such as 451-050 94 cm. These numbers indicate everything there is to know about that particular mechanical clock movement.

Identification is the first step

In order to purchase a new movement, the old number has to match up with the new one. The new movement will be exactly the same. It is not a knock off. All of the existing clock components will fit the new movement. Proper identification 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.

A new Hermle clock movement is best

As discussed in several sections, a new 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 movement will last another 30 years. This is not possible with a restored unit.

Mechanical Clock Movement Wear

Mechanical clock movement wear 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 movements brass plates.

What wear and where

If you look at your old clock movement, you will 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.

New Clock Movement Benefits

New clock movement benefits far outweigh the benefits of an overhaul. This section will explain why that is and what the best course of action is to get your clock working.

Getting the movement worked on

Clocks need to be oiled 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.

Every time the movement is worked on and re-bushed, it will last less and less time before it needs attention again. 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 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 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 movement is still in production, it is far better to just get the new one. Mass production makes the movement so affordable it will cost a fraction of the price of the repair work. The 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 movement so that it is better than new. Even the best clockmaker using the best equipment cannot make the movement better than a new one.

A new one is a factory fresh restart. The clock will be like it was originally when it was purchased from the store. The new movement will be made by the same people, with the same machines, and the 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 one 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 to consider getting repaired instead

If a unit is no longer in production and not available new, then a repair is most likely your only option. However we will try to convert it to a new unit 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 get it worked on.

Another movement to consider getting overhauled instead of replaced is the tubular bell, which is a high end movement. The price of a tubular bell unit makes an overhaul more attractive. This is because of the high price on the new ones which is currently around $1600. Usually the price is less for the new unit but instead these units are more costly than the overhaul by clockworks.com anyway. We can charge only $900 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 units.

Clockworks.com = The best repair service

We would love to do the overhaul here at clockworks.com and we do the best job. There are two ways to fix clocks; the easy way and the hard way. We only do it the hard way with no short cuts. 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 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.com work on your 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.

The new movement

New clock movement benefits usually do indeed outweigh the repair option. The movement will already come lubricated with clock oil so there is no need to oil it. The clock 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 movement, besides the dial and weights.

Once you get the hands and the clock dial out of the way (instructions included) it's only a matter of removing the two screws from underneath. The new movement can be swapped out by an experienced person in 10 or 15 minutes. An inexperienced person will take longer, but the point is that it isn't hard to do. There are some instances where a clock case was made in an annoying way that makes it more difficult, but for mass produced clocks this is not the situation. This more related to a few individual clockmakers who may have designed the case to make it more tricky to get the movement in or out.

Summary

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 produced clock movements and used aliases for names in a way. The movement could be stamped many names but really it will be made by Hermle. Some companies bought so many they were able to get there 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 disguised Aliases

Seth Thomas also Mason and Sullivan had not only there name, also there own internal numbering system. This was stamped on the movement, instead of the Hermle number. Since it is not a Hermle number, the number would need to be converted to what the real number is . 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. You do not have to think and decide if repair is better, the answer is a simple no. These companies went out of business long ago and the unit is over its lifetime. The lifetime is 25 - 30 years before it needs an overhaul or replacement. Both ST and Mason Sullivan on the movement would indicate the clock is about 40 years old.

The other Hermle Clock Movement Aliases are easy

Hermle Clock Movement Aliases on other clocks used only their name, and not there own internal numbering system on the Hermle movements. So basically if the clock is of post war German origin you can just look at the number and forget the name. The numbers will indicate what movement it is. If it is a Hermle movement its 3 or 4 digits followed by a hyphen, and then 3 more digits. Like this 1161-853 or 340-020 or 351-060. If the numbers look like this it is made by Hermle.
