What has a face and two hands but no arms or legs?

The correct answer to this riddle is a clock, which has a face that displays the time and hands that indicate the hours and minutes. This imagery is vital, as it uses familiar language to describe the features of a clock. The "face" refers to the part that shows the time, often marked with numbers, and the "hands" are the moving indicators that tell us the hour and minute.

While a watch also meets the criteria of having a face and two hands, it is typically considered a smaller timekeeping device worn on the wrist, whereas a clock is larger and often found on walls, tables, or as part of a built-in feature in homes. The other options, such as a doll and a computer, do not have these characteristic features in the same sense, as they do not represent timekeeping functions. This riddle typically leads to thinking about objects associated with the concept of time, guiding the responder toward selecting the timekeeping devices—hence the clarity of "clock" as the quintessential answer.
