Junghans Watch Mega Futura 26/4100.00. In 1990, we revolutionised watch technology with the Mega 1. The first radio-controlled wristwatch set new standards in design and technology. The Mega Futura brings back the unique retro look. Its minimalist design is also reflected in the time display which is selectable in an ultra puristic look in both the 12-hour and 24-hour displays. This revival model is limited to only 80 watches.
