Day difference 15 ~ 30 minutes, indicating mechanism only has an hour hand; 1500 ~ 15 10, Henleith of Germany first replaced the heavy hammer with a steel spring and created a small mechanical clock with a crown wheel escapement mechanism. 1582 or so, Galileo of Italy invented the gravity pendulum; 1657, huygens of the Netherlands introduced the gravity pendulum into the mechanical clock and founded the pendulum clock. 7.
