How Does A Clock Dial Work?

What time is it? You may now be turning your head towards the wall where your clock is hung. A clock has been of great help to the human civilization for a very long time. From its simple beginnings, the sun dial, which was used by our ancestors to tell time, years back when technology wasn’t that developed yet.

Now, how does a clock work? Basically, it runs through the use of the principle of oscillation, which is the repetitive movement created by the clock’s oscillator. This is in turn produces the “beat” for the clock, which must be at precise time intervals for the time being displayed on the clock’s face to be correct. Talking about what time it is, you mainly read time on clocks by looking at their clock dials. These dials are used in dial clocks or the more traditional forms of clocks as compared to digital clocks.

A clock dial generally refers to the hour hand attached to the clock, which does a single 360-degree revolution for 24-hour clock dials or 2 complete revolutions in the more common 12-hour clock dial. The first type is mainly used by scientists, pilots, and members of the military. This is preferred by some because of its unambiguous representation of a whole day at a time. Almost all of the clocks with 24-hour clock dials have 24 numbers marked on them. Because of this, these dials no longer need to indicate AM or PM.

Almost all modern clocks have 21-hour dials printed on their faces indicating the hour, and on other models, sixty dots or lines evenly spaced in a ring on the outer portion of the dial. This dots or lines indicate minutes and seconds. Time is read by looking at the placement of the clock’s hands which emanate from the center of the dial. These hands include: a short thick hand or the hour hand, a long thinner hand or the minute hand, and in some models, a very thin hand or the second hand.

Antique clock dials used in antique clocks or grandfather clocks are pretty lovely. Most of them might even have artworks and paintings on them. A lot of these designs can be seen even in a damaged antique clock dial through the use of ultraviolet light. These designs bring out the elegance in antique clocks making them very unique and popular among clock collectors.

Other forms of dials include radium dials, more commonly known as glow-in-the-dark dials. This works through the use of radium.
