History During the 1970s, the Swiss watch industry experienced a period of intense innovation as traditional mechanical watchmaking met the dawn of the electronic era. Rado, always a brand willing to push boundaries in both design and technology, embraced this transition with models like the Marstron. Powered by the ESA Dynotron series, a family of movements that utilized a traditional balance wheel driven by electromagnetism rather than a mainspring, these watches represented the cutting edge of transitional horology before quartz technology fully dominated the market. Today, these electro-mechanical pieces are highly valued by collectors for their unique place in watchmaking history and their unapologetically space-age design language.
