Watch: Jaquet Droz: Bird Repeater Openwork Automata

Swiss company Jaquet Droz has been making watches since 1738! In their film you can see the 8 different movements of this exquisite timepiece: with a worm in the mouth, mechanical blue tits tend their young ones beside a flowing river. One parent nods their head and stretches their wings while the other lowers a caterpillar to the eager young ones and the egg hatches. Amazing.
