Ulysse Nardin (1823-1876) made chronometers that won top awards at the 1862 London International Exhibition, the 1873 Universal Exhibition in Vienna, the 1877 Paris Exhibition, and the Swiss Government's trials at the Neuchatel Observatory in 1868. He was succeeded by his son, John Paul Nardin, and then his three sons. This example was made in 1943, and used aboard the S.S. Martha Berry in 1952. It is a 56 hour instrument with a spring detent escapement, and indications for hours, minutes, seconds, and up and down.
