You think the watch is merely an amazing concept? It’s real, coming from Thomas Prescher. All its components have been hidden in the bezel except the tourbillon, which is held in the middle of space by a single metal wire. The rotating cylinders at the top separately indicate the hours and minutes. Positioned between them is a spherical, moon phase calendar. At the bottom is also an interesting calendar—days on the left and months on the right. Integrated with a horizontal swinging oscillating weight based on gravity, the calendar would show you the dates no matter which side of the watch is held up. Also note that there’re two crowns, one for winding and the other for setting the time and calendar.
