Hi @velimir,

This is an admitted fact that man likes ancient cultures and species of the old days. It is basically a psychologically phenomenon and man likes to explore such innovative (for him) and different things. The mechanism of watch I read in my Physics book back in 2008. Quite similar pictures were presented by our school teacher that time to let us know how watch actually works on what principles.
These pictures and that pendulum took me to my old days. So true, blogs of Bro @velimir are always full of memories and joy <3
