Chronographs are special watches. It is separate “caste” in the watches world. Their sophisticated mechanism – jewelry work of many outstanding watchmakers. The first models of chronographs intended only for professionals. And only later time removed on a hand of the regular citizen. So, what is their feature?
The chronograph is the mechanism measuring intervals of time. It performs three main functions: start-up, stop, zeroing of a result. Inherently it is similar to a stop watch but more difficult. In the watch, it exists separately from the main mechanism and doesn’t influence its work in any way.
The chronograph was invented because of horse racing. Namely due to sharp requirement of exact measurement of time. When two horses came to the finish, sometimes it was difficult for judges to determine on what fractions of a second one participant beat another. Therefore, one great admirer of an equestrian sport invented the first prototype of a chronograph. It was the mechanism on which second-hand end has located the inkwell. When the clock was stopped it left a mark on the dial. So for the first time, it measured time spans to within a moment.
The main purpose of this mechanism – exact measurement of time spans. The similar tool is very necessary for many professions. Athletes, pilots, physicians, military – all of them estimated advantage of the similar tool. By means of additional dials and scales the pilot, for example, can determine the distance to the thunderstorm epicenter. Athletes measure movement speed, and physicians watch pulse and pressure. There is a set of professional chronographs, most of which are considered elite. Such chronographs’ are usually made by Swiss elite watch manufacturers. Such watches have more available models –replicas (learn more at https://www.elitereplicawatch.nl/)
The main objective of each of them – to write down exact indications of time. And even to make the calculation.
What are hours chronographs?
Simple. Such models are equipped with one button of management. The first pressing – start, the second – a stop and fixing of time, the third – zeroing of results.
Total. They have two buttons. The first is responsible for start-up and a stop. The second – drops indications. It is possible to start a chronograph as much as necessary. At the time of the last stop, the mechanism issues the total duration of the measured intervals.
Split chronograph. Possesses two-second hands. They are one over another. Such device can measure two-time spans if they began at the same time, but duration at them different. At such hours three buttons of management. The additional third button stops one of the arrows, during movement of the second.
Chronograph fly-back. Gives the chance one pressing the button to drop the previous indications and to start new counting.
