What is the least count of clock if it has hours hand minutr hand and second hand?

What fraction of a revolution does the second hand of a clock turn through when it starts at 12 and stops at 8?
The second hand of a clock completes one full revolution in 60 seconds, which corresponds to 360 degrees. When the second hand moves from the 12 to the 8, it covers 8 of the 12 hour marks. This represents ( \frac{8}{12} = \frac{2}{3} ) of a full revolution. Thus, the second hand turns through ( \frac{2}{3} ) of a revolution.

How could you make a analog clock more precise?
add a second minute hand. If you could add a second minute hand to an analog clock, you would be able to increase the precision by allowing the time to be determined to the second.
