Hello,
'LeukeKlok' means 'Nice Clock' in Dutch. Showing you here on this site is a part of my clock collection.
More clocks will be added in the near future, so check out this site again.

Original Clocks are clocks in their original form as they left the factory.
Modified Clocks are clocks that are not original anymore. The way they were changed, you can find in the description of that clock.
Design Clocks are clocks made by artists, one of a kind.

If you find a clock that you like and you are thinking about to buy it, you can always contact me by sending me an email.
I will give you answers to all your questions about those clocks.


And of course, here you can find more that got something to do with time...

Another way of telling the time.....

HOROLOVAR IGNATZ FLYING PENDULUM CLOCK

"The Craziest Clock in the World"
The original Ignatz Flying Pendulum Clock was invented by Alder Christian Clausen of Minneapolis, Minnesota. It was patented in 1883, and manufactured by the New Haven Clock Company under the name of Jerome & Co. in 1884-1885. Charles Terwilliger commissioned the German manufacture of this reproduction novelty clock in 1959, which continued until 1979. Beautiful and fascinating to watch run.
This clock doesn't have the original ball & cord. I just attached a cotton thread with small brass nut to it and it works.

NUFA Mystery Clock "Dutch Secret"

This was the first clock designed by Leendert Prins. It was made by NUFA in Amsterdam, Netherlands. It had an internal lamp that illuminated the plastic outer ring. Prins sold them as presentation gifts. The clock in the video below was made to work with the European standard of 240 volts 50Hz. Jefferson purchased the patents. This clock is dated between 1940-1950 and was valued at € 250.- by a Dutch TV program "Tussen Kunst en Kitsch".

Repair of a NUFA "Dutch Secret"

One of the four tooth of the perspex cog i found in the clock was broken, i don't know if it was the original cog. I made a new cog by 3D printing and 4 iron nails glued into it. It works.

AEG CLOCK

Nice clock in the shape of a voltmeter, probably a promotional gift from the AEG (Allgemeine Elektricitäts Gesellschaft = General Electric Company). This clock is dated between 1905-1910 and was valued at € 500.- by a Dutch TV program "Tussen Kunst en Kitsch" despite a missing leather handle.

Clock movement with electric winding by an electro-magnet

Small Swiss travel clock movement signed Cosmos
Small Swiss travel clock movement signed Cosmos, using the cheap version of the Reform movement, based on patents in 1928 and 1929. It has a spiral balance with a spring giving a power reserve of some three minutes to the going train. When the spring reserve is almost exhausted, a small arm linked to the barrel closes the contact and the electro-magnet gives a kick to an inertia arm with two balls at the ends. This winds up the spring with a pawl and ratchet and at the same time interrupts the contact. This movement is more commonly found in its high quality version, with 15 jewels and Breguet hairspring.

Marvin clock - Electromechanical self-winding clock movement from Switzerland

Small Swiss travel clock movement signed Cosmos
Signed MARVIN, using the high quality movement, with 15 jewels and Breguet hairspring based on patents in 1928 and 1929. It has a spiral balance with a spring giving a power reserve of some three minutes to the going train. When the spring reserve is almost exhausted, a small arm linked to the barrel closes the contact and the electro-magnet gives a kick to an inertia arm with two balls at the ends. This winds up the spring with a pawl and ratchet and at the same time interrupts the contact. This movement is more commonly found than the cheaper version of the Reform movement.
