Mystérieuse
These fascinating pocket watches were made in la Chaux de Fonds in about 1880. They have excentric glass dials with hands, which are installed on the glass. The "mystérieuse" phenomenon is because the hands are driven "invisible" together with the glass. Though, the glasses are interlocked outside and are driven by a very small train, which is in the upper part of the case. The case is glazed on both sides, so this is the effect of the validity of this mechanic.
