This particular creation consists a rectangular case that is mostly see-through except for the time, tourbillon, calendar, and because this is an automatic wristwatch, the oscillating weight. That begs the obvious question of "where is everything else?"
Thomas has hidden the rest of the movement within the bezel of this timepiece, giving it a totally transparent look. Symmetry is provided by two crowns, one used to wind the watch, the other used to adjust the time. The small round ball between the time-telling barrels is a three-dimensional moonphase indicator. The calendar function has been integrated into the oscillating weight and the genius of it allows the owner to wear the watch on either side and the display will be accurate.
To say the Mysterious Automatic Double Axis Tourbillon is unique is an understatement; it is truly one of a kind. In fact, it marks four firsts in watchmaking:
1. First automatic double axis tourbillon wristwatch with constant force mechanism in the carriage
2. First calendar implemented in the oscillating weight
3. First automatic movement with horizontal rotating oscillating weight
4. First mysterious automatic movement with upright standing main plates located on both sides of the movement.
