Do you know the difference?
A CHRONOMETER is a designation given to watches that have the highest level of precision.These watches have automatic and mechanical movements not quartz movement watches. Chronometers have near perfect mechanical movements, keeping accurate time always, unlike automatic or self winding watches.Two weeks of testing performance under varying climate conditions o obtain a pass certificate from the Swiss Official Chronometer Control(COSG) and thus are expensive watches.
These watches are not to be confused with CHRONOGRAPH watches ,which are basically a watch with stopwatch capabilities,dials that show the elapsed time.
