The clock had three dials which indicated hours, degrees and minutes
He later made an observational clock for the Istanbul observatory of Taqi al-Din (1577–1580), describing it as "a mechanical clock with three dials which show the hours, the minutes, and the seconds." This was an important innovation in 16th-century practical astronomy, as at the start of the century clocks were not accurate enough to be used for astronomical purposes.[26]

The next development in accuracy occurred after 1656 with the invention of the pendulum clock
Galileo had the idea to use a swinging bob to regulate the motion of a time telling device earlier in the 17th century
Christiaan Huygens, however, is usually credited as the inventor
He determined the mathematical formula that related pendulum length to time (99.38 cm or 39.13 inches for the one second movement) and had the first pendulum-driven clock made
In 1670, the English clockmaker William Clement created the anchor escapement, an improvement over Huygens' crown escapement
Within just one generation, minute hands and then second hands were added.
A major stimulus to improving the accuracy and reliability of clocks was the importance of precise time-keeping for navigation
The position of a ship at sea could be determined with reasonable accuracy if a navigator could refer to a clock that lost or gained less than about 10 seconds per day
This clock could not contain a pendulum, which would be virtually useless on a rocking ship
Many European governments offered a large prize for anyone that could determine longitude accurately; for example, Great Britain offered 20,000 pounds, equivalent to millions of dollars today
The reward was eventually claimed in 1761 by John Harrison, who dedicated his life to improving the accuracy of his clocks
His H5 clock was in error by less than 5 seconds over 10 weeks.
The excitement over the pendulum clock had attracted the attention of designers resulting in a proliferation of clock forms
Notably, the longcase clock (also known as the grandfather clock) was created to house the pendulum and works
The English clockmaker William Clement is also credited with developing this form in 1670 or 1671
It was also at this time that clock cases began to be made of wood and clock faces to utilize enamel as well as hand-painted ceramics.
