A chronograph is a specific type of watch that is used as a stopwatch combined with a display watch.A basic chronograph has an independent sweep second hand; it can be started, stopped, and returned to zero by successive pressure on the stem.Less simple chronographs use additional complications and can have multiple independent hands to measure seconds, minutes, hours and even tenths of a second. simple watch, without the stopwatch functionality, can be certified a chronometer, as can a clock, for example a ship's clock used for navigation. Originally the term chronograph was mainly used in connection with artillery and the velocity of missiles.
Evolved from the chronograph, the first actual stopwatch was crafted in 1869 by TAG Heuer, a famous Swiss luxury timepiece company. This device was used to measure intervals of time in fragments equal to 1/5th of a second. Later in 1916, TAG Heuer also created one of the most well-known stopwatches in history â the Micrograph.
