Hello

Today I show a wall clock with rotating pendulum (anniversary clock), which was very easy to build.
The basis is a wall clock with a quartz movement, which I have purchased at a flea market, for little money.

Initially I was only interested in the clock housing, matching a little bit the furniture (maple) in our living room.
When I looked at the clock closer, I realized that the replacement of the battery was solved differently, than usual.
So far I had only battery-powered wall clocks, which have an opening at the rear, to replace the battery.
For this fact,however, you have to take this clock off the wall.
At this clock it was much easier to accomplish. The dial, and the complete movement,is attached to a hinge on a support.
So you only need to open the clock and then fold out the dial to the left and you can quick and easy replace the old battery.

The very next moment I had the idea building a wall clock,replacing the quartz movement, with a movement of an anniversary clock.
The best, no need for front winding. I can leave the wind up mechanism on the back.

So, I picked up a Haller movement and did it.
How I did it? See the photos.
From the idea to the functioning clock, it took only a few hours.

Its a shame you were born to late. Your ideas could have
enhanced the world of clocks during the hay day of mechanical
clocks.

Very cool, DieteR! Did you have to change suspension spring size? How much?

Hello

First, I am pleased with the interest in this project.

I'd like to give answers for a few questions today.

I am using currently the original suspension spring.

Yes, it is adjustable for the rate. How I did it today, shows the left photo.
It is at the top of the pendulum and it is fortunately not visible behind the big clockface.
However, the regulation is still in the testing phase.
The time adjustment works in the range of about 1 second (14 to 16 sec).
I still have to work on it to make it look more professional.

Also, I have not yet finally decided on this pendulum.
I have a lot of them ( Originals, replicas and selfmades. See a few on the photos.
When finished, all my pendulums can be adjusted, in the most varied ways.
There is also the possibility of regulating of any pendulum, by the use of the special suspension. See the last Photo.

If there are any more questions, I'll answer with an appropriate text or photos.

Hello DieteR

Really like the clock and pendulums, and it has motivated me to have a go at building my own..

I would like to know some more information about the "special suspension".
Did you make these yourself?
I presume the principal is that one is located on top one at the bottom and by lengthening and shortening you control the rotational speed?
How is the suspension wire connected?

Many Thanks

Darius
