Set the Time:
- Initially, the timer displays 00h:00m:00s:00cs (hours, minutes, seconds, centiseconds).
- You do not need to set a time manually; it starts from zero and counts up.
Start the Countdown:
- Click the Start button located in the center below the timer display.
- The timer will begin to count the time upwards from zero, updating every centisecond.

Pausing the Timer

Pause the Timer:
- If you need to pause the timer at any moment, simply click the Pause button.
- This button is found next to the Start button under the timer display.
- The time display will freeze at the moment you pressed pause.
Resume the Timer:
- To resume timing, click the Start button again.
- The timer will continue from where it stopped.

Resetting the Timer

Stop the Timer:
- To completely stop the timer and reset the time, click the Reset button.
- This button is located next to the Pause button.
Reset the Display:
- Upon clicking Reset, the timer will stop, and the display will revert to 00h:00m:00s:00cs.
- You can now start the timer again from zero whenever you are ready.

The History of the Stopwatch

The stopwatch, a tool indispensable in sports, science experiments, and everyday timekeeping tasks, has a rich history marked by technological advances and increasing accuracy in time measurement. This chronicle of the stopwatch not only reflects its evolution but also its impact on various domains, particularly in athletics and scientific research.

Early Beginnings

17th Century: The concept of a stopwatch began to materialize with the advent of mechanical clocks. Early versions, however, were not designed for accuracy in seconds.
1816: The first modern stopwatch was invented by Louis Moinet, a French horologist, for use in tracking astronomical objects. Moinet’s device was capable of measuring intervals as short as 1/60th of a second.

Development and Refinement

1820s: Nicolas Mathieu Rieussec developed the first marketed stopwatch, used by King Louis XVIII to time horse races. This version dropped ink onto the dial to mark elapsed time, which led to the device being called a “chronograph,” from the Greek words for time and writing.
1844: Adolphe Nicole refined the chronograph by incorporating a re-setting feature, which significantly enhanced its utility and marked a pivotal moment in its development.

Industrial Revolution and Mass Production

Late 19th Century: With the Industrial Revolution, stopwatches became tools for efficiency studies, particularly in workplaces. The precise timing facilitated by these devices was crucial in optimizing mechanical processes and improving labor efficiency.

The 20th Century and Beyond

1910s to 1930s: The manufacturing of stopwatches expanded rapidly, with companies like Heuer (now TAG Heuer) leading the field. Heuer introduced stopwatches and chronographs that catered specifically to sports and industrial timing.
1960s: The advent of quartz technology represented another significant leap in accuracy and reliability. Quartz stopwatches could measure time more accurately than their mechanical counterparts and were less susceptible to mechanical wear.
1980s: The digital revolution introduced stopwatches with digital displays, which provided users the ability to read time quickly and with unprecedented clarity.

Modern Era

21st Century: Today, stopwatches are often integrated into multifunctional devices such as smartphones and sports watches, leveraging advanced digital technology. These modern versions feature capabilities like memory storage, which can record multiple lap times, and connectivity to upload data to computers or online platforms.

Timeline of the History of the Stopwatch
