In the Zeitwerk, you have three discs – one of the hours, two for the minutes – and instead of displaying the time vertically like you find in most historical digital displays, the time is read from left to right like you would on an actual digital clock.
With the Zeitwerk, the minute displays jump instantly, and while that sounds easy enough, consider the amount of power required to move these discs around. All this is made possible by a special escapement integrated between the barrel wheel and the balance. A rementoir gains, holds, and releases the energy required to move each disc every 60 seconds in a small burst of power, and then over the remaining minute rebuilds. This continues in a cycle.
