This clock is the prototype for a limited production run. The movement was designed and hand-built by an electrical engineer, hand tuned to keep more accurate time than the typical quartz movement. The vacuum tube display is made of Russian numitron vacuum tubes, which are number displays using what are essentially light bulb filaments to display the time. As my clockmaker friend explains it, word of the LED had not yet reached these Soviet factories, and so they were still producing these tubes well into the 60s and 70s. He has lowered the voltage across the tubes to keep the functioning for a long time, and has thousands of these tubes in his basement, so there are repair parts available.
The case itself was inspired by some 18th century Federal style furniture, built by John and Thomas Seymour, whose cabinetwork is still in museums, and in the White House. The case is mahogany, the inlays are figured maple, the carving was all done by hand. The glass for the face has been decorated with an imitation gold leaf, and then back-painted with black. (Production models will use actual gold.) The leaf design was modeled after a secretary desk that the Seymours built, but miniaturized to fit the scale of the clock.
Dimensions: 24" tall, 7" wide. The door for the face of the clock is 6" wide.
