What would you measure using a chronometer?

one ahould read "Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time" by Dava Sobel (1995). This is a best-selling book about John Harrison, an 18th-century clockmaker who created the first clock with sufficient accuracy (hence chronometer) to be used to determine longitude at sea. This was a very important development in maritine navigation.
