Thanks for the compliment. If interested you can see the entire build here: www.my-time-machines.net/astro_index.htm

I know of Martin Molin's Marble Machine and he has communicated to me on my creation. His machine is very popular partially because he has to physically interact with it to play the machine. It is visually and mechanically complex. The visuals are more eye catching as flying marbles are not something one often sees, and, of course, there's the music! This machine, (I will try to be as unbiased as I can), has a different level of refinement as the parts are small and numerous at 8000. It is also all done in metal which is a more difficult material to work with. The finish is high quality with a mixture of gold and silver plate. It also took a lot of research into astronomy and its implications to translate 71 astronomical functions into mechanical representations. A lot of the machine was first created in mock ups made of plastic to test concepts before metal was cut. It took 12 years to build plus design time.

Thanks. But I think this is the last inspiration. Fifteen years id long enough!

Yes, one of a kind. Took 2 years to design, 12 years to build.

@@MarkFrankclocks to call it exceptional or brilliant would be an understatement. It is a marvel, a masterpiece, a magnum opus

Hello Yavuz, I'd be happy to see you if you ever visit the USA. Great to know there are people from all over the world looking at it!

It did take twelve years to construct plus another couple to conceive and design.

@@MarkFrankclocks that's amazing... It's not a surprise, it's truly a wonder

There are many examples of complex clocks beginning in the 14th century. Their work is superb and decoratively unmatched even by today's standards. It simply took the builders a lot longer to make unless they created a consortium (which was almost always the case). One man rarely has all the skills needed to build a monumental machine. Another wonderful machine, not a clock, but the fastest calculator in the 17th century by Muriel in 1859, do give it a look. In chronological order, noteworthy clocks are: Giovanni Dondi, Italy, 1365-1381, 16 years, one man, skeleton Eberhard Baldewein, Germany, 1563-68, 6 years, several people Phillip Mathias Hahn, Germany, 1739-1790 Johann Georg Nestfell, Germany, 1757-1763. 6 years, skeleton Marie Antoinette clock, Abraham Louis Breguet, 1783, 44 years, Musée d'Orsay in Paris Antide Janvier, France, Chef d’ Overe, 1789-1801, consortium, 12 years Paul Pouvillon, Nogent-sur-oise, France, 1918-1939, 21 years, one man, skeleton Daniel Vachery, France, 1938-1967, 29 years, one man, partial skeleton Rasmus Sørnes Clock, Norway, 1946-1966, over 20 years, one man, skeleton Jens Olsen, Denmark, designed over 50 years, built 1944-1955, 11 years, by consortium of 10 people, skeleton Hans Lang, Germany, 1986, one man Türler, Switzerland, 1986-1995. 9 years, commissioned by Franz Türler, designed by Dr. Ludwig Oechslin; built by; Jörg Spöring, skeleton. The clock stands 2.2 meters or just over 7 feet in height. It contains 1.2 tons of brass and 251 wheels on 155 pinions. Astronomical Skeleton Clock, 2003-2021, actual build time 12 years, one man and commissioner (me).

No. I had a hand in the design, but this was a commission I made from a superior clockmaker, Buchanan of Chelmsford, out of Australia. it has taken over 12 years to build.

@@MarkFrankclocks I have sent an email :)

2 years of designing, 12 years of building, and a lot of clockmaking skill

Magnificent! Super proud to have owned a Mark Frank’s tower clock!!!

It's driven on 4 remontoire weight drives that are automatically rewound by 4 springs, I believe. It looks to be entirely mechanical.

What is the source of all the background broadband noise? It randomly varies in intensity, I’m assuming it is building ventilation nose and it does guiet down considerably several minutes into the video.

Can you tell me what is copper on the machine?

​@@MarkFrankclocks From its color, I thought all parts, gears and others are from copper, isn't it?

The main body of the machine, base, frames and pillars are brass. The larger, lower train wheels are made of pink bronze, while the smaller and behind-the-dial complications wheels are brass. I wanted all wheels in pink bronze but this material is much harder and thus machine than brass, there are after all over 500 wheels in the machine. All silver colored steel are made of stainless steel. Half of the wheels run in dry jeweled bearings since they are lightly loaded and turn less than one rotation per hour. Faster turning and/or heavier loaded wheels run in ceramic bearings which need no oil. The escapement is Harrison's oil-free design. This makes the machine a dry runner. Oil is the greatest source of failure in clocks as it dries out or collects dirt turning it into a grinding paste on the arbor's pivots. As Breguet is purported have said" Give me the perfect oil and I will give you the perfect watch". Of course if one can build a device requiring no oil - that's the perfect situation.

@@MarkFrankclocks Thank you for the detailed reply. It is really a MASTERPIECE. I'm not specialized in machines or watches, but I love to watch extraordinary machines working, I've enjoyed every second watching the full length of your video, this is a very innovative hard work, thank you for sharing this work.

@@MarkFrankclocks how is the polish maintained? Where is this beautiful clock today?
