Surface hours early just to show the hours, not minutes and seconds. Hour minute show on his face reflected in the writings of Paul Almanus manuscript in 1475. There are a few hours of the 15th century made in Germany that show minutes and seconds.
In the 15th century and the 16th, carpentry hours more bloom, especially in the metalworking towns of Nuremberg and Augsburg, and in Blois, France. There is a simple desktop timer alarm berjarun only one, with the interval between markers hour is divided into four quarters that the timer alarm can be read accurately the near-exact 15 minutes. Meanwhile, the timer alarm is also a show craftsmanship and skill guidance astronomy and musical animation. Bolosan cross rhythm created by Jost Bürgi, developers also remontoire, in 1584. Bürgi's creations hour is a major improvement in precision timer alarm because the time was right in a minute a day.The hours of this help astronomers of the 16th century, Tycho Brahe to observe astronomical events more precisely than before.
Mechanical weight-driven astronomical online timer alarm which features bolosan verge-and-foliot, marches whisk gear, alarms, and the symbolism of the moon cycles described by the Ottoman engineer, Takiyuddin in his book, Al-Kawākib Fī durriyya wadh al-al-al-dawriyya bankāmat (" Stars Top Distinction for Construction Machinery timer alarm "), published in 1556-1559.Similar to the European alarm timer alarm early 15th century,   it can beep at a certain time with pegs located on the wheel face. At the appropriate time, the switch on the device twang pegs. The timer alarm had three each face pointing the hours, degrees and minutes. Then, Takiyuddin produce a timer alarm observatory to observatory Taqi al-Din in Istanbul (1577-1580). He memerikannya as "a three-sided timer alarm machinery that calculates the value of the hours, minutes and seconds." This is one of the important innovations in the practice of 16th century astronomy, as at the beginning of the century, the hours available are not quite suitable for use in astronomy.

Development to improve the accuracy of hours to advance further with the creation of the pendulum timer alarm after year 1656. Galileo's pendulum swinging the use of shadow to control the movement of the tape recorder at the beginning of the 17th century. However, Christiaan Huygens considered to be the author, as he determines mathematical formulas that relate the length of the pendulum to time (99.38 cm or 39.13 for one second movement), thus disclosing the first pendulum-driven timer alarm in the world.
The excitement of the pendulum timer alarm had attracted the attention of designers, resulting in a growing diversity in the resulting form of hours in the world, especially at large stand created to house the pendulum and exchange hours. Appreciation is given to the artisans at English, William Clement for developing this form of timer alarm circa 1670-71. At the same time, the skin is also an increasing number of hours is made of wood while using the timer alarm face hand painted enamel and pottery.
French decimal timer alarm from the time of the French Revolution
On 17 November 1797, Eli Terry received his first patent for an invention hours. Terry is known as the founder of the U.S. industry trade hours.
Tailor-hour Scotland, Alexander Bain, patented inventions hours of electricity in 1840. Electric timer alarm main spring lock with an electric motor or electromagnet and armature. In 1841, he first patented the electromagnetic pendulum.
Electronic development in the 20th century to produce the types of hours, of no exchange hours, otherwise the time recorded by other means such as vibration tuning fork, the behavior of quartz crystals or quantum vibrations of atoms. Mechanical online timer stopwatch was mostly driven by a battery.
