A small and complex machine



A nicely filmed video that shows the design and fabrication of a Patek Philippe wristwatch. The effort and care put into machining, finishing and then assembling the tiny parts of the watch's mechanism is amazing.

In an earlier post The evolution of complexity in watches I did reflect upon how deceptive the apparent complexity of watches could be:
Above are three main types of time pieces: ... a cheap crystal watch, ... a mechanical watch's mechanism, ... a digital alarm clock.

Of the three the mechanical watch visually seems to be the most complex, but there is little doubt that the digital clock is actually more complex by orders of magnitude. While the switches, LEDs, capacitors and resistors are simple enough, hidden within the IC chip, and discernible only by microscope, are circuits of immense complexity.
Indeed, just like extremely large scales escape us, our perception is far too crude to make real sense of something so small. In the end we only see a slice of reality.
