Hermle clock movement 1051 - 1050

Hermle clock movement 1050 or 1051 units are spring driven and triple chime. They are made by the Hermle clock company of Germany.

The movement

All the Hermle clock movement 1050 or 1051 units have a 120mm plate size. Spring driven and triple chime movements that is popular with bracket style cases.

The hands shaft length is either 27.6mm long or 33.2mm long, and is indicated by the last number. If it says 0 as the last number it has the 33.2mm and if it has the 1 instead like 1051-021, it has the 27.6mm. The hammer location is either back, bottom, or side.

The Chimes

Westminster, St Micheal, or Wittington on the quarters for chime options. After it plays out the top of the hour chime, it will strike out the hours.

Hermle Clock Movement Identification

Identification is done with the numbers on the back plate of the Hermle clock movement. Not from the manual that came with the clock, and not off the wood case. On the back plate of the clock movement you will see the numbers such as 451-050 94cm. These numbers let us know everything we need to know about the mechanical clock movement itself. This tells us if its weight driven, the plate size, and every other aspect of the movement.

When the numbers are matched, the new movement can be ordered. The new movement will be the exact same and not a knock off. Therefore all of your existing clock components will fit just the same a it did.

As discussed in a different section, the new movement is the way to go without a doubt. The new unit is a fraction of the price of an overhaul on the old one. You will have the clock back and running in the shortest time instead of waiting months and sometimes years for the overhaul to be completed. The movement will last another 30 years without much complaint, you cant say this about an old one that was restored.

Mechanical Clock Movement Issues

Mechanical Clock Movement Issues arise 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.

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.

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 Mechanical Movement Reasons

New Mechanical Movement Reasons to get the new one when we can just repair the old one? The reason is because it is still in production. Its still made in mass production in Germany, so this means its available for a lot less cost. Even the best repair job from the best repair professional, cannot make it as good as a new one.

New Mechanical Movement Reasons are because it can ship from USA the same day you order it. The time it takes you to get you're clock up and running is very short. A repair can usually take months and then you are still left with a used overhauled movement rather than a new one.

When you receive a new movement it is the same as you're old movement. All clock component parts such as weights will fit on to the new movement. The cost of a new movement is less and when it's installed it should last another 25-30 years without intense service. Over the years, if there is improvements that can be done on the movement, the factory updates them. We here at Clockworks offer only the highest grade mechanical clock movements and they come with a 2 year warranty.

Conclusion

The new unit will cost less and ship now. It will be far better in every way than getting the old one restored. You will have a new movement in days instead of the used one back in months.

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.

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.

The numbers on the back plate of the 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.
