in the wirtual world, all complications work perfectly, the light travels flawlessly on decorated calibre shinnier than a mirror.
in the real world, some show half working prototypes to attract interest, but displayed under a glass bell.
Some do however come with working prototypes. I recently got the chance to see such prototype in motion, and motion is really the important word in this case.
have a look at this short spherotourbillon video. This tourbillon does spin fast and keeps excellent timing. about 1/2s per day, I have been told! that is a mere 2 1/2 minutes per year !!!
well done JLC.
(thank you Mr J.)
