A chronograph is an electronic instrument that has one or more hands that can be halted in the command with the explicit purpose of measuring time. You may never have heard of a chronograph, but I certainly know what they are timers. They are one in the same. Today come in two basic forms, mechanical and digital.
Mechanical chronograph, like with wristwatches, operate on a spring mechanism and must be manually wound. The controls consist usually two or three buttons. Pressing the button starts and stops the time tracking mechanism, represented by second and minute hand, which can restore the position starting by pressing an additional button.
For most purposes, mechanical chronographs are accurate enough, though anyone wishing high degree of accuracy using a digital stopwatch. An example of someone who needs a digital version would be a track and field athlete, or any number of other Sporting efforts where time is measured by the fraction of a second. These accurate clocks have the ability to show tenths, hundredths, thousandths even seconds, and using the same extremely accurate and reliable oscillator quartz watches. Digital chronographs are without doubt the most popular form of the chronograph today. As the technology has improved, so has the accuracy of the clock.
The first chronograph like instrument was developed in 1720 by an Englishman named Graham, who is now known as Father of the Chronograph Â'the. Basically, then a clock that can be quickly started and stopped and was accurate to 1 / 16 of a second. Although standards today that it is terribly inaccurate, was a fantastic achievement at that time.
The first actual chronograph was a century later by a Frenchman named Rieussec. His watch had points at which to measure elapsed time, and was the first to bear the name Â'chronographÂ. His invention uses a pencil to mark on the line in itself an arc whose length can be used to measure the time that the mechanism had operated for. Was a very complex mechanism that proved to be very accurate and reliable.
The Greek roots of Â'chronograph word 'suggest that in reality means Â'time writing ', and since Rieussec's invention was the only one involved in writing is the only real chronograph. Chronographs today we are all called stopwatches because I think if you were to ask any person about a chronograph, which would not know what we're talking about. Although technically a misnomer, many people still refer to stopwatches as chronographs and names are for nearly all intents and purposes interchangeable.
It is common now to see the wristwatches with a stopwatch built right in the face of it. Analog watches are have built a mechanical chronograph is simply referred to as chronographs, and usually carry a heavier price tag due to its complexity. However, are very reliable and very useful if you have a need for such a thing.
