Answer
A mechanical stopwatch functions by using a spring-driven mechanism to measure elapsed time.
- Winding and Starting: The crown (the knob at the top) is used to wind the mainspring, storing energy. Pressing the crown typically starts the stopwatch, releasing the spring's energy to move the hands.
- Measuring Time: The large hand on the main dial measures seconds, completing one full rotation in 30 or 60 seconds. The small hand on the sub-dial measures minutes, advancing one mark for each full rotation of the large hand.
- Stopping and Resetting: Pressing the crown again stops the hands, allowing you to read the elapsed time. A third press of the crown usually resets both hands back to zero, ready for the next measurement.
