Description: As mentioned elsewhere on this site, this ca. 1970 model is another of several models Rado made that suggest a fascination with the "Space Race." This example features the rather rare black dial (as opposed to the silver or grey version) and globe-with-orbitals logo and printing of argent.
Present on this series is the rotating anchor logo previously seen only on watches with automatic winding. Hands are of varied widths of rectangles, with luminous filling, and the hours are indicated by wide hash marks--white lines denote the quarter-hour markers except at 6:00 where the date window is located (other dial colors feature orange or yellow accents). Case has off-set setting crown (signed), inset case back medallion typical of models seen in Japanese market, and faceted crystal. A less common example of this watch was also made; it features pointed hands and smaller, monochromatic hour markers. The dial of this watch sometimes appears to be blue, as shown in one of the photos below.
The Marstron with black dial is not often seen and was apparently made in smaller numbers than even the fairly uncommon grey version. A 1972 catalogue page showing the Marstron line includes three variants of this style, but not that with black dial.
