Musical automaton ring with moving figures

Now here is a unique piece. This antique ring is an automaton with moving figures built into it! Granted, I don't fully understand how you operate the ring, but the mere concept is unspeakably cool.

From the eBay item description:

This is a very fine and unusual 18K gold mechanical ring with a moving woman and men are playing a song by turning a crank. The background is fine glazed. The ring is in a beautiful and working condition from Isaac Daniel Piguet, Genève, circa 1805.
