Zenith Rainbow....

What watch has a fractional masthead sail boat on its caseback? A Zenith El Primero Rainbow Chronograph....


Zenith Watch was born to a 22 year old named Georges Favre-Jacot. He was one of the first to understand the importance of the inter-changeability of parts for rationalising production, thereby improving precision and reliability of mechanical watches.


He grouped together all the different areas and know-how that make up watch making. Thus, one of the very first true Swiss manufacturing companies was born.


By the time Jacot retired in 1929, Zenith Watches had made watch history, winning grand prix medals for timekeeping precision at international expositions in Geneva, Paris, Barcelona, and Neuchatel. In 1969, Zenith won renown for introducing the world's first automatic chronograph movement, the El Primero -- which was the movement for the R**** Daytona for years.
