It enabled the navigator accurately to compare the time of local mid day to the time of mid day at the Greenwich meridian. The time difference is directly convertible into a longitude reading.

The problem of the city to be named "Athens" was solved when it was judged by Zeus.
"Houston, we have a problem" was said during the Apollo 13 mission in 1970. This phrase was actually slightly misquoted from the actual communication, which was "Houston, we've had a problem."
No one says the line "Houston, we have a problem" in real life. John Swigert said "Houston, we've had a problem" But in the film Apollo 13, the producers changed the line to "Houston, we have a problem". Another reason not to believe too much in Hollywood movies.
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.
No, they simply promulgate the delusion by claiming to be against it. The problem rises in that it is not possible to be antithetic to what does not exist.
John Harrison invented the marine chronometer, a device used to accurately determine longitude at sea. His invention revolutionized navigation by allowing sailors to calculate their east-west position with precision. Harrison's marine chronometer played a significant role in solving the "longitude problem" and improving the safety of sea travel.
John Harrison, the 18th-century clockmaker, created a total of five significant timepieces, known as H1 through H5. These clocks were designed to solve the problem of determining longitude at sea. Harrison's innovative approach to marine chronometers revolutionized navigation and earned him recognition for his contributions to timekeeping.
No problem at all. It was a piece o' cake.
Despite the normal importance of any clock associated with time accuracy, John Harrison’s clocks had its very own special purpose and importance. His series of inventions have always been helpful in solving the longitude problem faced by the sailors and navigators in the 17th century. The idea is simple, for every 15° that one travels eastward, the local time moves one hour ahead. Similarly, travelling West, the local time moves back one hour for every 15° of longitude. Therefore, if we know the local times at two points on Earth, we can use the difference between them to calculate how far apart those places are in longitude, east or west. Although accurate pendulum clocks existed in the 17th century, the motions of a ship and changes in humidity and temperature would prevent such a clock from keeping accurate time at sea. Harrison’s entire career was aimed in solving this problem in which he was successful after a series of different designs for the clocks started with “Harrison’s Marine Timekeeper No.1 (H1)”, H2, H3 and the more portable H4.

Early sailors used the sun and constellations to fix longitude and latitude before they had clocks. In 1761, John Harrison designed and built a "sea watch" that was accurate to 25 seconds in a trip across the Atlantic. The problem was the change in temperature, pressure and humidity as the ships sailed.
