See that fancy looking design on the bottom? Is tthat simply design or does it move or smoething? Thanks in advance.

Answer 1

it is the pendulum

it rocks back and forth to move the second hand.  It is run by a complicated mess of gears and springs.

Hope this helps.

Answer 2

The gold-colored mercedes-shaped thing goes around one one, then back the other way quickly, in a rocking fashion. It makes it look more interesting that way.
