An applied Rado anchor logo sits proudly below twelve o'clock, while the lower half of the dial is defined by the distinctive printed atom logo and a symmetrical date window at six o'clock displaying striking red numerals. The sweep second hand remains clean, and the entire dial presents brilliantly with no significant spotting, staining, or visible damage. Case and Crystal The stainless steel tonneau-shaped case is presented in honest vintage condition, featuring a brushed top surface that transitions into polished flanks.

The combination of the vertically brushed silver dial, vibrant red date numerals, and the historically important ESA 9154 electronic movement makes this a standout addition to any vintage portfolio. 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. / Second Vintage SKU: RAD-RMX-0047
