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 movements 1050 or 1051 units have a 120mm plate size. Spring driven and triple chime movements are popular with bracket style cases.
These units take a number 8 key to wind it and one wind lasts 8 days on a full wind. Also, it is available in a balance wheel version such as the 1050-020 or the pendulum version like the 1051-020.
The Hermle clock movement hand shaft length is either 27.6mm long or 33.2mm long. Hence, the last number of the movement is indicative of this length. So, if it says 0 as the last number it has the 33.2mm hand shaft and if it has the 1 instead like 1051-021, it has the 27.6mm hand shaft.
The Hermle clock movement hammer location is either back, bottom, or side. In other words, the hammers that strike the chime rods on a Hermle clock movement can be on the back of the movement, the bottom of the movement, or on the side of the movement.
The Chimes
A Hermle clock movement will play Westminster, St. Michael, or Whittington on the quarter hours for chime options. After it plays out the top of the hour chime, it will strike out the hours.
- Less cost than a cleaning
- Should last 25-30 years, a repair would not
- Easy to install, we can help if need be
- Ships the same day
So I have a 1050-20. I let the wind expire by accident and let it stop after about 8 days. Now instead of winding 8 times to a full wind. I only can wind it 4 times to a full wind and that’s on all 3 winds. Any thoughts?
Tired movement, what is the date code on the back ? See this link to find out how old

Is there a difference between the 1051-030 and 1051-030A Hermle movement?
The non A unit has rods for the chime hammer heads, the A unit has flat bars that the hammer head are mounted too.
The new units are A units.
The replacement is the same if no A before, the replacement is an A unit. The fit is the same, slight chance it is needed to readjust the position of the chime block and rods
Please order the 1051-030 from this link, it will be shipped as an A unit.

Hello. I picked up a brand new Hermle 1051-050 movement years ago from someone who was cleaning up – but minus the pendulum. What length should that be and what weight should the bob be? Thanks for the help!
What is the CM number that is stamped on the back plate of that unit?
Also please double check to be sure it says 1051-050 because that would not be a common clock movement

And do I absolutely need a leader for the pendulum or can my pendulum hook directly on to the verge? I’m making this clock into something quite different than the average clock look…
Thank again for the help!

Now that its fall and I can get back to my clocks…. Yes. confirmed it is 1051-050. Pic attached. Still waiting to hear what length and weight the pendulum and bob need to be. Thank you!
Please order a pendulum for a Hermle 66cm movement in wood stick style from this link

You would need to select a bob diameter that has a couple of inches to swing on each side of your inside of the clock case.

Viking 1151-050/94cm/66bpm. I need to know the weight chart scale and shell diameter for this movement. I believe the weights are the wrong size. It will not TickTock without adding a little weight to it. I can not get it to chime unless, I apply a little pressure on the right weight.
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.)
Thank you !

Good morning,
Can you please help, my Hermle movement has a broken main spring it is a 1051-020.
Do I have to take the barrel out of the movement to find out what barrel I require.
Thank you.
