The company Nivada was established in 1879 in Grenchen in Switzerland. In the US their dials are signed "Croton" or "Croton Nivada Grenchen", which is a reference to the company’s North American distributor in New York.
Nivada’s flagship model is the "Chronomaster Aviator Sea Diver", which was launched in 1963 and produced until 1978. This chronograph can also be used as an aviator’s or diver’s watch; a number of different manual wind calibres were used for this model, such as the Valjoux 92 and 7733 or the Landeron calibre 248. The revolving bezel has two scales, for minutes and hours. The red 30-minute counter has a countdown function for regattas.
