Henry Grandjean was one of the first to enter the South American Market. He was also, along with Ulysse Nardin, one of the first to establish a marine chronometer manufacturing business in Switzerland, and be an initiator of the Neuchâtel Observatory. In 1851, at the first Universal Exposition in London, Grandjean received a First Class medal. His list of medals continues until 1868 when the company won an award for its marine chronometers. In the meantime, they also received at least eight different awards, not including those from the Observatory of Neuchâtel. Henry died in 1879 but it appears that the company continued for the next twenty years until 1899, the year in which Rossel & Fils registered their name as successors, who were also most likely running the company during these 20 years. On January 9, 1908, Rossel & Fils transferred the title to Charles-Ferdinand Perret.
