Here is an interesting 6” tall by 4-1/4” wide by 1-7/8” deep table, desk, or shelf clock. The mechanism is tucked behind the back of a bent piece of opaque off white, uniformly colored Lucite (acrylic). Takes a single AA battery.
The hands are made of metal, the hour hand is in red, the minute hand is in yellow. The seconds are indicated by a black and blue disc that turns. Set off from the base by just under an inch via four metal prongs is a 1/8" thick, transparent Lucite square (4 1/4" by 4 1/4") that is screened on the back in white with a very pop art, 80s modern design. The design looks almost like a TV test pattern.
I hesitate to call it mid century, but this clock would probably fit nicely with mid century décor. The effect with the rotating seconds disc is terrific, as the center of the clock turns from white and black - to white, blue, and black - to white and blue - to white, blue, and black - and then repeats. The motion gives the clock a kinetic art appeal.
Unsure of maker, no markings. I have no information about this clock other than it looks fantastic.
