Detailed Description for Stop Watches

Stopwatches are a handheld timepiece designed for measuring the amount of time elapsed from a particular time when it is activated for the time when a piece is deactivated. A large digital version of a stopwatch designed for viewing at a distance, as in a sports stadium, is called a stopped clock.




The mechanical stopwatch is powered by a mainspring, which must be periodically wound up by revolving the knurled knob at  the top of a watch.The timing functions are traditionally adjusted by two buttons on the case. Pressing the top button to start a timer running, and pressing the button a second time stops it, leaving a elapsed time displayed. A press of the second button then reset a stopwatch to zero. The second button is used to record split times or lap times. When the split time button is pressed while a watch is running, a display freezes, allowing a elapsed time to that point to be read, but a watch mechanism continues running to record total elapsed time. Pressing a split button a second time allows the watch to resume display of total time.


Digital electronic stopwatch is available which, due to their crystal oscillator timing element, is much accurate than mechanical timepieces. Because they contain the microchip, they often include a date and time-of-day functions as well. Some may have the connector for external sensors, allowing the stopwatch for be triggered by external events, thus measuring elapsed time far more precisely than is possible by pressing the buttons with one's finger. Stopwatches that count by 1/100 of a second are mostly mistaken as counting milliseconds, rather than centiseconds. The first digital timer used in organized sports was the Digitimer, prepared by Cox Electronic Systems, Inc. of Salt Lake City Utah (1971).It utilized a Nixie-tube readout and gave a resolution of 1/1000 second. Its first use was in ski racing but was later used by the World University Games in Moscow, Russia, the U.S. NCAA, and in the Olympic trials.


The stopwatch function is also present as an extra function of many digital wristwatches, cell phones, portable music players, and computers.
