Discovering the Aikon Mercury free-hand display

Suzanne Wong, Editor-in-Chief of WorldTempus, explains how the Aikon Mercury works in detail.

At first glance, the Aikon Mercury is like most other watches, with its central hour and minute hands and small seconds at six o'clock. But tilt it slightly and you will then see something that might frighten you: the hands spin freely and no longer give the time. Don't worry, the watch is not broken. As soon as you hold the watch upright again, the hands return to their original position and show the exact time.

How does it work?

The explanation lies in a new “free hand” system developed by Maurice Lacroix, that works with the natural force of gravity to read and display time from a double snail-cam mechanism hidden beneath the dial.
