In the early 1960s, only one chronograph managed to combine nine functions into a single watch: the Nivada Grenchen Chronomaster Aviator Sea Diver. The Chronomaster, with its 100-meter water resistance (328 ft, 10 bar), was the first timepiece to combine a stopwatch with a tachymeter scale, diving watch, pilot’s watch, timer, yacht timer, and GMT display; not to mention, of course telling the current time. In print ads, Nivada promoted the Chronomaster with slogans such as “Super-Chronograph” and “The world’s busiest watch – has more uses than ever counted.”
Watch is in overall good condition 8/10, running and ready to wear or gift!
