Featuring Franck Muller's patented way of not using hour and minute hands to show the time.

The resounding success of the Double Mystery collection has led to this new version improved by an Imperial Tourbillon. This complication makes this innovative display system more complex. Compared to a traditional system, the hands are replaced by two discs with two arrows at 12 o’clock. The first arrow is placed on a central disc and allows the reading of the hour whereas the second one is placed on an outer disc allowing the reading of the minutes. 

The Imperial Tourbillon gives to this Time Keeper another dimension.

Technical skills, dexterity and the Swiss watchmaking knowledge are showed by this admirable complication. Presented with a mat black dial and a steel watch-case, this outstanding time piece will be also available full set with diamonds which will have undergone a complete metamorphosis to become a real piece of jewellery.
