Mystery watch
A mystery watch is a type of mechanical watch where the movement is transmitted to the hands through an invisible wheel, often a transparent crystal wheel.
The first transparent dial watch, the so-called montre mystérieuse by the French firm Armand Schwob et frère, although the factory was located at the Swiss town of La Chaux-de-Fonds, is in the collection of several museums worldwide, such as (in alphabetical order): Deutsches Uhrenmuseum, Musée d'art et d'histoire of Neuchâtel, Musée international d'horlogerie (MIH) or the National Watch and Clock Museum.
