Hello

I like to present here again one of my conversion or DIY projects.
Today it is a very small 400 Day Clock based on a Haller miniature movement.

Essentially, I wanted to build the whole clock as small as possible ( the height)
but with a reasonable Expenditure.
An important thing to me was, that it still would be running for 400 days.

After the clock had fulfilled this condition in a test setup, I have
begun to build it visually as close as possible to the appearance of a well-known
torsion pendulum clock.

Now here's the result.
The clock has a maximum height of only 83mm !!!
How small is in reality, can be seen in comparison with the Becker ball pendulum,
or if it stands next to a "normal-sized" clock, or on my hand.
See the photos "MiniaturUhr 01, 02 and 03".
Photo 04 shows the clock from all sides and Photo 05 some construction details.
The photos were partially made during the construction and test phase.
In the photo 06 the clock stands on a glass base and the same clock on a brass base.
(Both are nothing more than inverted coaster.)

The photo "Originalgröße" allows to print the clock in it's actual size.

At this point, I very interested in whether someone knows a clock in
similar size, or even smaller than mine.

Hello

Thanks for all Your posts

Now it is complete with pedestal and glass dome

Two answers:
The pendulum rotates a full 360 °
The suspension Spring has the original thickness of 0,056mm.
It is, however, adapted to the special built pendulum.
(Gently thinned)

If the board survives another 100 years, someone is going to be on here inquiring about the "DieteR" manufacturer! I wonder what kind of answers he'll get?:p

If the board survives 100 years, perhaps they'll find this thread!

Very impressive! Ingenuity is still alive and well within the craft.
Consider an article for the Bulletin and or The Torsion Times?

Thanks so much for sharing.

Here are a couple of my past projects along the same lines, using midget Kern 400 day movements.

I always suspected that I am among the least talented person on this discussion board. Now I have no doubt. Wow to all of the miniatures posted!

Here's another mini 400 day in a 4-glass case next to a full size front wind "Anniversary" 400 day. This is not a carriage clock case.Again a Kern midget movement.

Hi Dieter, fixoclock, i like your work very much. Although not as small as dieters I built this one a while ago out of a Kern midget movement I had lying around. Apart from the dome, base and hands ( meadows and passmore ) I built it as a project to see if it would work with a disc pendulum. The pendulum is 2 inches across and 90% of its mass including the weights is at the outer edge to give reliable operation. The dial is varnished paper and the suspension is a horolovar thinned for the application. Adrian. minature clock.jpg minature clock8.jpg minature clock6.jpg minature clock7.jpg minature clock3.jpg
