For chronographs used in paintball and similar:
The modern chronograph consists of two sensing areas called chronograph screens, which contain optical sensors that detect the passage of the bullet. The bullet is fired so it passes through both screens, and the time it takes the bullet to travel the distance between the screens is measured electronically.
If you are talking about marine chronometers, they are clocks that are precise and accurate enough to be used as a portable time standard. They can be used to determine longitude by means of celestial (use of stars) navigation.
Nowadays the word 'chronometer' is used when talking about watches, and means that the watch was tested and certified to meet certain precision criteria.
A marine chronometer measures time. It is a very precise instrument because it can also be used to measure the longitude of the ship at sea using the time shown and the angle of the sun.
For latitude the sextant, and later for longitude, the marine chronometer.
No. A chronometer measures time. Wrist watches, egg timers, and hour-glasses are chronometers.
If you used a sextant and a marine chronometer you could determine your position and plot this on a map using latitude and longitude. If you did this regularly you would be able to plot your course.
John Harrison developed the first practical marine chronometer, H4, to accurately calculate longitude at sea. This invention revolutionized navigation by providing a reliable method for determining a ship's exact position, therefore improving the safety and efficiency of long-distance sea travel. Harrison's work directly contributed to the solving of the "longitude problem" and significantly advanced maritime exploration and trade.
There are so many people who use a chronometer. People who work in the marine use it for celestial navigation among others.

A marine chronometer measures time. It is a very precise instrument because it can also be used to measure the longitude of the ship at sea using the time shown and the angle of the sun.
John Harrison is credited with inventing the first marine chronometer in the mid-18th century. His invention greatly improved navigation at sea by providing an accurate way to determine longitude.
Chronometer is a noun.
The device is called a marine chronometer.
For latitude the sextant, and later for longitude, the marine chronometer.
Chronometer Chronometer
The marine chronometer is used to tell time on a ship. It was created in the 18th century and is very precise and accurate.
The ship's captain used a chronometer to accurately navigate the vast ocean.
A chronometer is a watch that is designed for the highest amount of precision and accuracy. The time on a chronometer watch is almost always accurate.
