Silver Hunting Cased Erotic Automaton

A large early 20^th Century Swiss lever with concealed erotic automaton in a decorative silver full hunter case. White enamel dial with subsidiary seconds, Arabic numerals, blue steel hands.   Silver full hunter case, both covers decorated in high relief, the front depicting a bust.  The back with floral decoration marked "H Frsl Depose".  Opening the back and silver cuvette reveals a nun, apparently kneeling at prayer, receiving the attentions of a member of the clergy from behind.  The scene springs to life when the silver slide in the band is activated.
