This riddle describes a "clock." A clock has a face that displays the time but lacks eyes and a mouth. Its "face" serves as the surface where the numbers and hands are shown, but it doesn't have any facial features like a human or animal.
It sounds like you're describing a riddle or a playful statement. The phrase "6 plus 7 is 1" could refer to a clock where adding 7 hours to 6 o'clock results in 1 o'clock. The description of having a face and two hands but no arms or legs might symbolize a clock, which has a face and hands that indicate time.
