There were only clocks prior to John Harrison's invention of the "Sea Clock". It was invented to find your current longitude on the earth used for ships at sea. Regular Clocks which used a pendulum were too susceptible to movement, humidity and temerpature for reliability until Harrison's invention of a balance spring and escapement which replaced the pendulum. Later Harrison miniaturized his Sea Clock which resulted in better accuracy and reliability into what is now known as a pocket watch.
