More about Nivada Grenchen:
Nivada was founded in Grenchen (Granges) in Switzerland, in the mid 1920's by Jacob Schneider. The company took off after the second World War under the leadership of Jacob's son Max Schneider who focused his product and marketing on sports and adventure with watches such as the "Aquamatica", a water resistant and antimagnetic watch used by the US navy during an exploration of the South Pole.
The most famous watch of the company is the Chronomaster "Aviator Sea Diver" introduced in 1963 to compete with the succesful Omega Speedmaster, Heuer Autavia and the Breitling Navitimer. With its name the watch was to be a multi-purpose chronograph for both divers and aviator, with a specific subdial for timing oxygen level for a diver but also a bezel with a GMT graduation on the bezel for pilots. The watch came in different combination of dial and calibers such the Valjoux 92 and the 234 but also the 7733 and 7755.
A victim of the Quartz Crisis, Nevada Grenchen would eventually shutter. In the years since, the Chronomaster has become a favorite of collectors around the world.
In 2020, the watch was revived in a re-edition of which the present watch is an example.
