Ergo 2011 Digital battery operated clock, West Germany
The clock is 9.25" long, 5.75 " tall, and 4" in depth. It has an embossed leather cover, with a silver bezel featuring white numerals on a black background.
The clock is battery operated one "D" cell, but it does not have a quartz movement. It ticks like a normal clock It has a balance spring. It has a regulator screw that can slow or speed the clock up which is accessed through a hole in the bottom of the clock.
Strange but interesting clock.
I could not find any information on the maker.
