The Junghans J101.65 is a radio-controlled solar movement used in the Max Bill Mega Solar collection. A direct descendant of the original MEGA-1 from 1990 (the first radio-controlled solar watch), it features automatic time synchronization via radio signals and a perpetual calendar accurate until 2400. The solar cell provides approximately 3 years of operation on a full charge. This represents Junghans' most technologically advanced movement, combining German engineering with environmental sustainability.
