Stopwatch
analog or digital timepiece designed to measure an amount of time, having push buttons to start/stop and reset a time stopping action
A stopwatch is a timepiece designed to measure the amount of time that elapses between its activation and deactivation.
A large digital version of a stopwatch designed for viewing at a distance, as in a sports stadium, is called a stop clock. In manual timing, the clock is started and stopped by a person pressing a button. In fully automatic time, both starting and stopping are triggered automatically, by sensor.
The timing functions are traditionally controlled by two buttons on the case. Pressing the top button starts the timer running, and pressing the button a second time stops it, leaving the elapsed time displayed. A press of the second button then resets the stopwatch to zero. The second button is also used to record split times or lap times. When the split time button is pressed while the watch is running it allows the elapsed time to that point to be read, but the watch mechanism continues running to record total elapsed time. Pressing the split button a second time allows the watch to resume display of total time.
“Stopwatch” enters the record as analog or digital timepiece designed to measure an amount of time, having push buttons to start/stop and reset a time stopping action. Crown Archives preserves that source wording while asking what Stopwatch, analog and digital can confirm, complicate or overturn.
Why this record matters
“Stopwatch” is worth following because a concise public description often conceals a longer documentary argument. Here, Stopwatch, analog and digital provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 19, 2026. The linked authority identifier is Q843994. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
