A marine chronometer is a timepiece which is precise enough to be used as a portable time standard. On an "important" piece, this can result in a catastrophic loss in originality. People who work in the marine use it for celestial navigation among others. It is an astronomical method of calculating the longitude at which a position line, drawn from a sight by sextant of any celestial body, crosses the observer's assumed latitude. It was created in the 18th century and is very precise and accurate. They serve as portable time standards. Care of the Marine Chronometer. Traditionally, the term refers to the marine chronometer, a rugged mechanical instrument used at sea to keep time for navigational purposes.

Marine chronometers have become highly collectible. They are NOT designed to be forgiving and it is very easy to do extensive (expensive) damage. Today a cheap quartz watch keeps accurate time, and many chronometers on ships are battery operated. Just to be clear, this blog is mainly about the marine chronometer, sometimes called a box chronometer. Marine chronometers are precise, specialized clocks for finding longitude at sea. Origin: National Air and Space Museum, Smithsonian Institution. Image Date: 2012. Credit: National Air and Space Museum, Smithsonian Institution. These accurate timekeeping devices were crucial for the Age of Exploration. Related Resources. Some of them were made for use in the air and for use by surveyors, but usually do not differ fundamentally from the basic marine chronometer. When first developed in the eighteenth century it was a major technical achievement, as accurate knowledge of the time over a long sea voyage is necessary for navigation without electronic or communications aids. Creator: Bruce Morser. Traditionally, the term refers to the marine chronometer, a rugged mechanical instrument used at sea to keep time for navigational purposes. Chronometer, a timepiece that is exceptionally accurate. Type: Illustration. The design of the escapement (the interface between the balance and the power train) is such that doing these things will likely result in serious damage. A marine chronometer is a timepiece that is precise and accurate enough to be used as a portable time standard; it can therefore be used to determine longitude by means of accurately measuring the time of a known fixed location, for example Greenwich Mean Time (GMT) and the time at the current location. Unfortunately, these historically important, monetarily valuable instruments were never intended to be in hands unfamiliar with their operation. The spring-driven marine chronometer is a precision timepiece used aboard ship to provide accurate time for celestial observations.A chronometer differs from a spring-driven watch principally in that it contains a variable lever device to maintain even pressure on the mainspring, and a special balance designed to compensate for temperature variations. … The chronometer is not like a clock or watch where you can turn hands backwards or adjust the seconds hand with impunity. The marine chronometer is used to tell time on a ship. Marine Chronometer. There are so many people who use a chronometer. Chronometer, a timepiece that is exceptionally accurate. to make a thread dedicated to quartz marine chronometers. Marine chronometers are very impressive timepieces that were developed for use on ships for correct navigation. A marine chronometer is a timekeeper precise enough to be used as a portable time standard; it can therefore be used to determine longitude by means of celestial navigation. Topics.

Most clocks and watches tend to lose or gain time each day when compared to the atomic clock. Hi I believe it's about time (get that? )
