I don’t think an analog clock is particularly intuitively obvious. There are two or three hands, not one, and how do you know what each one means? Also, in general, NONE of them point to the numbers that make up the time. The hour hand is generally pointing between two numbers, not pointing at one, and some clocks don’t even have hour numbers, or show them in Roman numerals, adding another complication. The minute hand’s value is totally unrelated to the numbers printed on the face and must be memorized (most clocks don’t of course have minute numbers on the face). The second hand is there solely to add to the confusion. If you use clocks every day, reading it becomes second nature, but it certainly requires some training at first.
