| [* red] Ultra low-power microcontroller | |
| [* orange] [http://en.wikipedia.org/wiki/Quartz_clock#Mechanism|Quartz crystal|new_window=true], operating at 32,768 Hz | |
| [* black] When power is applied to the crystal, it oscillates 32,768 times a second, filling a counter register in the processor. When the register fills, it overflows back to 0, triggering a pulse of the motor—and one second on the second hand. | |
| [* black] This incredible processing power is capable of maintaining time accurate to [http://tf.nist.gov/general/pdf/2276.pdf|within 1 second per day|new_window=true]! |
