The Aurora Clock was designed in the 1970s by physicist Jordan Kirsch and architect Jim Hamilton.
The dial of the Aurora Clock has a mysterious structure in which the color changes with a gradation.
There is a light bulb inside, and by using polarized material on the minute hand, the dial, and the dial, the entire dial rotates to create this aurora-like sight.
This item is a vintage item from around 1970.
Size: Height 7.8in , Width 5in , Depth 8in
Material : Chrome plated steel
It operates normally, and the clock does not deviate from the time and operates normally without any problems.
The plug is a type that can be used normally by plugging it into a Japanese outlet.
Due to its age, the film on the dial has deteriorated and is peeling off.
That's why the dial looks cracked. It's not broken, it's just that the film has deteriorated and become crumbly.
However, please understand that this will inevitably happen due to the material and age.
The main body has been polished, but since it is old, there are scratches and deterioration in various places. Regarding the back, the back cover was probably remade later.
The back cover is held in place by a magnet inside the main body. (One of the magnets is also missing.)
This itself was modified later, so perhaps the back cover was also modified.
The magnet is weak, so even if the back cover is attached, a slight vibration may cause the back cover to come off and fall off.
However, since the light bulb inside this watch gets hot, it is better not to seal it with a back cover, so it may be better to leave the back cover open.
But if you do that, the light will come out from the back.
I think changing the bulb to an LED would solve the heat problem, but I haven't tried that.
