Is the angular velocity of rotation of hour hand of a watch greater or smaller than the angular velocity of Earth's rotation about its own axis ?

Hour hand completes one rotation in 12 hours while Earth completes one rotation in 24 hours.

So angular velocity of hour hand is double the angular velocity of Earth. $\left(\omega=\frac{2 \pi}{T}\right)$.
