Analog clocks hang on walls, sit on desks, and adorn wrists in daily life.
Inside these clocks, the second hand sweeps steadily across the face, marking each passing moment.
This hand completes a full circle every 60 seconds, repeating the motion without stopping.
The sweep continues as the clock's internal gear train advances it smoothly and persistently.
Powered by a consistent energy source, the process runs cycle after cycle.
The second hand moves independently of whether anyone watches the clock or interacts with it.
Time display relies on this ongoing sweep, which operates steadily in the background.
