A watch complete with all the originally supplied appurtenances is rarely found; here, the certificate even retains its original envelope. On the back of the certificate are all the awards won by Grandjean since 1841. At the first London Universal Exposition in 1851, the firm won a First Class medal. The list continued until 1868, when an award was won for marine chronometers. They received at least eight other awards between the two, not including those from the Neuchâtel Observatory. Henri Grandjean, along with Constant Girard (later Girard-Perregaux), was one of the first to enter the South American Market. He was also one of the first, along with Ulysse Nardin, to establish marine chronometer manufacturing in Switzerland.
