The ‘’Royal Chronometer’’ name, for the English-speaking market, was registered on May 8, 1908. The first of these were a series of pocket watches delivered to Brazil. Mr. A. Campos, a Vacheron & Constantin agents, had organized a lottery system in which subscribers paid a monthly fee to take part in a series of draws. The holders of the winning tickets would be given a watch and the other subscribers would be entered into the next draw. This system proved to be so successful that A Campos delivered a total of 3022 watches between 22 October 1907 and 31 December 1911 - an amazing 80% of the production of the Chronomètre Royal, utilizing the caliber RA22’’’73 made during this period. The Chronomètre Royal was made in several sizes, from 12 to 22 lines, and was housed mostly in gold cases, more rarely in silver ones.
