FRANCK MULLER DOUBLE MYSTERY

The Double Mystery collection is characterized by an innovative display system. Compared to a traditional system, the hands are replaced by two discs and the numerals by two indexes. The first index is placed on a central disc and allows the reading of the hour whereas the second index is placed on an outer disc allowing the reading of the minutes.

 

This invention represents a technical challenge and was patented in 1998. It consists of an additional module placed on the basic movement. The hour indication comprises a disc fixed on the axis of the hour wheel and the minute indication is constituted of a toothed crown external and concentric to the hour disc.

 

The hour and the minute are read through two indexes: the index placed on the central disc indicated the hour and the index placed on the external disc indicated the minute.
