Flip clock Space Age Plastic, Metal - 1960-1970 - Flip Clock Jump Hour

Vintage SA01 jump-hour desk clock, Made in Japan, original from the 1970s, rare. Electromechanical movement powered by a 1.5V battery. Very distinctive design; it’s not labels but rotating numbered rollers. Aesthetically in really good condition for its age, inner battery compartment clean and without signs of oxidation. The clock works and keeps good time (it's still a mechanical clock that ticks, not a modern quartz clock), and the day of the week also functions well. It also has an alarm function, but although the adjustment and the top button work well, I can’t get it to activate, so I can’t guarantee its operation. The clock will be shipped without a battery to avoid shipping issues.
