The English watchmakers, for instance, consider a chronometer to be a portable clock or watch with a detent escapement, although they used the term before detent escapements were developed.In the Swiss and French watchmaking circles, a chronometer is a watch that has been given an official rating certificate by the observatories at Neuchatel or Geneva. - A device capable of measuring small units of time.Ever wonder what that term or description of a watch or clock part means?
