Chronometer, portable timekeeping device of great accuracy, particularly one used for determining longitude at sea. Although there were a couple of earlier isolated uses, the word was originally employed in 1779 by the English clock maker John Arnold to describe his sensationally accurate pocket.
A marine chronometer is a precision timepiece that is carried on a ship and employed in the determination of the ship's position by celestial navigation. It is used to determine longitude by comparing Greenwich Mean Time (GMT), and the time at the current location found from observations of celestial bodies.
May 30, 2024 · In a nutshell, a chronometer is a watch that has been certified by some regulating body to be of very high accuracy, usually fitting into a fixed set of specifications. But it’s not quite that simple, as these specifications and testing methods vary greatly – so let’s explore further.
Sep 8, 2017 · Not too long ago chronometers were the only instrument used on board ships for accurate time keeping for purpose of navigational calculation.
Chronometer, 1802. Thomas Mudge, one of the watchmakers following Harrison, designed this instrument. Like Harrison's timepieces, Mudge’s were extremely inventive and complex. And like Harrison, he won funds from the Board of Longitude but had to struggle to receive them.

May 8, 2018 · chronometer. The design, construction, and successful replication of marine chronometers, or precision timekeepers, was one of the great scientific triumphs of the early modern period. This scientific instrument was crucial to the accurate determination of longitude (or east-west direction from a given meridian on the globe) to vessels at sea.
Aug 8, 2020 · A chronometer is not to be confused with a chronograph – that’s any watch with a stopwatch function for measuring time. A chronometer watch is essentially a fine-tuned watch that keeps better time than most.
