The clock and figures dates back to the 16. century. The clock itself is a 24 hour clockface (2x12 in two halves) with only one hand.
The figures are Prince George and the Dragon, Kirsten Kimer and Per Døver.
When Prince George steeps and hits the dragon with his sword the dragon screams. Kirsten Kimer hits the bell as quarter signals while Per Døver hits the hours.
