A Ulysse Nardin marine chronometer is an extremely precise, mechanical marine chronometer, originally manufactured by the Swiss company Ulysse Nardin for seafaring, scientific expeditions, and navies worldwide. Before the invention of GPS and radio signals, sailors relied on accurate timepieces to determine longitude at sea. From the mid-19th century onward, the Le Locle-based company supplied over 50 of the world's navies with its marine chronometers and won numerous precision competitions. Historical marine and shipboard chronometers were mounted in special wooden cases with gimbals to ensure the movement remained horizontal regardless of the ship's movements.
