This clock represents the inner working of a modern cpu in a mechanical manner. Just like a CPU, it contains registers, ALU, memory, Buses, and a Control Unit. To display the time, the middle register uses binary numbers to indicate the hour (a reading of “0010” indicates 2 o’clock, for example). For minutes, the clock uses the HEX numerals on the outer edge of the device, so “05” represents “5,” “0A” indicates “10,” and so forth.
