The 24-hour analog dial continued to be used, but primarily by technicians, astronomers, scientists, and clockmakers. John Harrison, Thomas Tompion, and Mudge [7] built a number of clocks with 24-hour analog dials, particularly when building astronomical and nautical instruments. 24-hour dials were also used on sidereal clocks.
Analog clocks display time with an analog clock face, which consists of a dial with the numbers 1 through 12 or 24, the hours in the day, around the outside. The hours are indicated with an hour hand , which makes one or two revolutions in a day, while the minutes are indicated by a minute hand , which makes one revolution per hour.

Maarten Baas's Schiphol Clock. Real Time is an art installation series by Dutch designer Maarten Baas. It consists of works in which people manually create and erase the hands on a clock each minute. Portions of the time depiction are completed using CGI after the motions of the painter are filmed separately and repeated to complete the 24 hours.
The time is usually based on a 12-hour clock. A method to solve such problems is to consider the rate of change of the angle in degrees per minute. The hour hand of a normal 12-hour analogue clock turns 360° in 12 hours (720 minutes) or 0.5° per minute. The minute hand rotates through 360° in 60 minutes or 6° per minute. [1]
