The mechanical self-winding Spiroscope model by Louis Moinet highlights the oscillations of the balance, which is visible through its added bridge. The latter is a modern version of the famous balance-cocks made by the 19th century French watchmakers, which were fastened with screws so as to decorate and protect the movement. Its round, pure, and powerful new case houses an exceptional mechanical self-winding movement. The caseback reveals an unexpected vision with the entirely original weight shaped like the Côtes du Jura® motif. It winds in both directions, and its oscillations are highlighted by a superimposed shield bearing the Louis Moinet symbols. (less info)
