The AURORA CLASSIC is an updated version of a beautiful clock from the 70's. Some version of it has been in production for over 25 years. Its classic contemporary design was honored by the Museum of Modern Art.

What's so special? A very unusual case, beautiful colors, and --- a mystery! There are no colored lights, no prisms, and all the materials are clear, gray, or milky. Yet there is continuously changing colors and surprising color 'shifts' when the second-hand-disk overlaps the minute & hour-hands. There is something else going on!! First you intuitively sense - something is wrong with the colors. Then you walk around while watching the clock and surprise --- the colors changed! Plus inside the clock you see a clear second-hand-disk changing through a purple-blue-green color range, twice/minute as it rotates. It turns out, the color changes have to do with polarized light and a phenomenon called birefractance. Vectors of light are being rotated as they pass through each material which is very different from color filtering.

The uniquely sculptured case is solid brass which takes a much higher polish than the older aluminum cases. This we nickel plate for durability and to achieve the chrome contemporary color most of you prefer. Add to this fluorescent lamps for cool running (so you don't cook the materials and motor) and you have the best in contemporary design --- a worthy successor to the original AURORA. The sale price is $325 in chrome color, or $375 in 24k gold plate. This is 40% off retail.

We occasionally have rebuilt (used repolished cases with new motors and filters) AURORAS available for $195, or $260 with fluorescent lamps. Allow one week for assembly.
