Zenith Rainbow Flyback Chrono 02.0480.405 – El Primero Precision Built For Real Performance

Some chronographs are admired for their looks — others are respected for what they represent. The Zenith Rainbow Flyback Chrono 02.0480.405 belongs firmly in the latter category, standing as a tribute to Zenith’s unmatched chronograph legacy and its pioneering role in high-frequency automatic movements.

This pre-owned Zenith Rainbow Flyback Chrono 02.0480.405 features a robust 40mm stainless steel case paired with a matching stainless steel bracelet, striking the perfect balance between sport and refinement. The black dial is highly legible, accented by polished hands and Arabic numerals, while the unidirectional bezel underscores its functional, professional character. A discreet date window between 4 and 5 o’clock adds practicality without disrupting the dial’s symmetry.

At its core lies the Zenith El Primero Calibre 405, an in-house automatic chronograph movement celebrated by collectors and industry experts alike. Operating at a high frequency and equipped with a flyback function, it allows the chronograph to be reset and restarted instantly — a feature historically reserved for professional timing applications. With a power reserve of approximately 50 hours and water resistance up to 100 metres, this watch is engineered for real-world performance, not just display.

This example is presented in mint condition with minimal signs of wear, carefully inspected, and authentication certified for complete peace of mind. It comes with its original box, further enhancing its appeal to collectors and enthusiasts who value completeness and provenance.

For those who appreciate true horological substance, the Zenith Rainbow Flyback Chrono offers something increasingly rare: a historically important, in-house chronograph that delivers technical excellence, everyday versatility, and long-term collectability — all without compromise.
