Model: Marstron (version B)

Movement: ESA 9154 Dynotron - 13-jewel battery-powered electro-mechanical with balance wheel. Battery bridge signed "Rado"
Description: This ca. 1970 model is one of several models Rado made that suggest a fascination with the "Space Race" which culminated in the 1969 Apollo 11 moon landing. Apparently, Rado's designers subsequently set their sights beyond the moon and named this futuristic watch "Marstron"--a reference both to the idea of space travel and to the forward thinking which was producing reliable electronic and electro-mechanical wrist watch movements at the time. This example features the globe-with-orbitals logo--also seen on the Rado Hardtron (essentially a Diastar with Dynotron movement)--and 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--orange lines denote the quarter-hour markers except at 6:00 where the date window is located. Seconds hand is not red-tipped. Case has off-set setting crown (signed), inset case back medallion typical of models seen in Japanese market, and faceted crystal of sapphire or hard mineral. A less common example of this watch was also made; it features pointed hands and smaller, monochromatic hour markers.
The case shows minimal wear, is very presentable and is keeping accurate time. A slight blemish on the dial is difficult to notice except under magnification. Service history is unknown, but the movement is clean; date functions properly at midnight.
The original bracelet is present on this watch.
