Vacheron & Constantin first began using the Chronomètre Royal name in 1907 when the brand first launched pocket watches bearing this prestigious name. From the 1950's the name was only used on watches with a chronometer certified movement. These were among the first wristwatches with hacking seconds and certified as chronometers for civilian use.
