The brand solidified its reputation with the introduction of the Antarctic in 1950, the first waterproof automatic watch. This timepiece gained fame when it accompanied members of the U.S. Navy's Operation Deep Freeze I during their South Pole expedition from 1955 to 1956.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eIn 1961, Nivada Grenchen launched the Chronomaster, a versatile waterproof chronograph designed for aviators, divers, and sports enthusiasts. The company continued its innovative streak with the release of the Depthomatic in 1964, the first diver's watch featuring a depth indicator, followed by the Depthmaster in 1965, capable of withstanding pressures up to 1,000 meters.\u003c\/p\u003e\n\u003cp\u003eAfter a period of dormancy, Nivada Grenchen experienced a rebirth in 2018, reintroducing two of its most iconic models—the Chronomaster Aviator Sea Diver and the Antarctic—at the forefront of its revival.
