Chronometer

A highly accurate timepiece, particularly one designed for use at sea to determine longitude by comparing local time with a known time, typically Greenwich Mean Time (GMT). It maintains a consistent rate despite variations in temperature, pressure, and motion. Essential for navigation before the advent of radio and satellite systems, chronometers were vital for accurate charting and maritime safety, allowing sailors to determine their precise location on the globe. The precision of these instruments revolutionized navigation and maritime exploration.
