Observatory chronometer

An observatory chronometer is a timepiece that has passed stringent testing and a slate of accuracy tests. Thus, the "observatory trial" developed as the standard process for determining accuracy of timepiece movements. If the chronometer passed the stringent testing, it would be certified.
