The automatic flyback chronograph movement of the Super KonTiki, or caliber 3916A, belongs to Eterna's legendary caliber 39 family. With a frequency of 28,000 vibrations per hour, its movement boasts a remarkable 60-hour power reserve; it also dazzles with its exceptional finishing: the rhodium plating of its components and the meticulous ornamentation of its oscillating weight. Like all the Manufacture's in-house movements, the Super KonTiki chronograph boasts a precision worthy of the most accurate chronometers, with 70% of its components made directly in Grenchen, the birthplace of Eterna.
