![]() In the Ottoman Empire, Taqi al-Din invented the "observational clock", which he described as "a mechanical clock with three dials which show the hours, the minutes, and the seconds." This was the first clock to measure time in seconds, and was used for astronomical purposes, specifically for measuring the right ascension of the stars. īefore the late 15th century, a fixed hand indicated the hour by pointing to rotating numbers (in contrast with the modern system of a fixed dial and rotating hands). It featured a 24-hour analog dial, including a large marker for each hour and a small marker for each minute, along with medium-sized markers to indicate half-hours and quarter-hours. To represent the hours and minutes, Ibn al-Haytham invented a clock face. In the early 11th century, Ibn al-Haytham's Maqala fi al-Binkam described a mechanical water clock that, for the first time in history, accurately measures time in hours and minutes. The knowledge of weight-driven mechanical clocks produced by Muslim engineers in Spain was transmitted to other parts of Europe through Latin translations of Arabic and Spanish texts on Muslim mechanical technology. A similar weight-driven mechanical clock later appeared in a Spanish language work compiled from earlier Arabic sources for Alfonso X in 1277. The first weight-driven mechanical clocks, employing a mercury escapement mechanism and a clock face similar to an astrolabe dial, were also invented by Muslim engineers in the 11th century. It was not until these mechanical clocks were in place that their creators determined that their wheels could be used to drive an indicator on a dial. These clocks were erected as tower clocks in public places, to ensure that the bells were audible their purpose was to mechanize and eliminate the human element from the ringing of bells as a public time signal. The original clocks were striking clocks: their purpose was to ring bells upon the passage of a certain amount of time. The face of the Movado "Museum Watch" is known for a single dot at the 12 o'clock position.Ĭlocks existed before clock faces. Occasionally markings of any sort are dispensed with. In some instances, particularly in the case of watches, the numbers are replaced with undifferentiated hour markings. ("IIII" -rather than "IV"- is often used to mark the fourth hour to achieve symmetry with "VIII.") Clocks using only Arabic numerals first began to appear in the mid-18th century. Longcase clocks (also known as grandfather clocks) typically use Roman numerals for the hours. The two numbering systems have also been used in combination with the prior indicating the hour and the later the minute. Clocks can indicate the hour with Roman numerals or Hindu-Arabic numerals. Some special purpose clocks, such darkroom timers and sporting event clocks, are designed for measuring periods less than one hour. The term face is also used for the time display on digital clocks and watches.Ĭertain clocks have 24-hour analog displays and are marked accordingly. Typically, the dial is numbered 1-12 indicating the hours in a 12-hour cycle.
