The main components of this music box were made by Reuge while the guys from MB&F took care of the radical design of this thingie. There are 2 independent movements, a winding propeller, a mainspring barrel and a horizontal cylinder with pins which can create 3 different melodies. There’s also a vertical comb with individual hand teeth to sound each note.
That’s how this true work of art is able to play classic tunes and many more. The weight of the device is a little under 3kg and apparently there will be only 66 units produced, 33 units in white and 33 in black.
