Free throws are shot without the clock ticking, though in the NBA, there is a 10-second clock to shoot a free throw or else it is forfeited. At the end of the game, the buzzer automatically ends the game. However, if a player has released the ball from his hands before the buzzer sounds and the ball makes it through the basket, the score counts.
Early versions erred by less than one minute per day, and later ones only by 10 seconds, very accurate for their time. Dials that showed minutes and seconds became common after the increase in accuracy made possible by the pendulum clock. Brahe used clocks with minutes and seconds to observe stellar positions. [112]

It is also possible for quartz clocks and watches to have their quartz crystal oscillate at a higher frequency than 32 768 (= 2 15) Hz (high frequency quartz movements [4]) and/or generate digital pulses more than once per second, to drive a stepping motor powered second hand at a higher power of 2 than once every second, [5] but the electric ...
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 ...
Pendulum clocks were used as time standards until World War 2, although the French Time Service continued using them in their official time standard ensemble until 1954. [70] Pendulum gravimeters were superseded by "free fall" gravimeters in the 1950s, [ 71 ] but pendulum instruments continued to be used into the 1970s.
Display of time zones (usually, a second hour hand displays the Coordinated Universal Time) world time; Quickset date; small seconds - seconds are displayed in a subdial; Foudroyante (also called "flying seconds"- a dedicated hand that completes a full rotation in one second indicating fractions of a second)
