Square Wall Clock – How is it Classified?

A Square Wall Clock is a clock of square shape that is designed to be hung on the wall. This is one of the famous styles of clocks and is designed particularly to satisfy various needs. Although the main purpose of these timepieces is just that – to show time – these can make aesthetic decorations for homes, offices or anywhere they are set up in. Know about some of the main types of this type of clock.

Square Mechanical Wall Clock
It is constructed out of basic mechanical components, and not electrical components. It generally draws power from falling weights or a coiled spring. The types of clocks referred to as Cuckoo Wall Clocks, Grandmother Wall Clocks and Grandfather Wall Clocks come under this category. The accuracy of timekeeping of this clock is based on the engineering and construction of the components.

Square Electric Wall Clock
The Square Wall Clock is powered by electricity drawn from a battery or any other source of power. Battery-powered clocks come with quartz technology and make use of electrical pulses for accurate timekeeping. Rewound Wall Clocks, Electronic Wall Clocks and Impulse Wall Clocks are the 3 primary sub-classifications in the category of electric clocks. In Rewound Wall Clocks, there is a mechanical power supply system as well as a mechanical time dividing system. Electricity rewinds power supply systems such as Falling Weights or a Coiled Spring. Electronic Wall Clocks are powered by an electrical system as well as an electrical power supply to divide time. Impulse Wall Clocks are powered by a mechanical system, such as a pendulum and a balance wheel, for the division of time.

Square Pendulum Wall Clock
These clocks divide time with a pendulum. The pendulums swing in an accurate way, which improves the accuracy of the Square Wall Clock. How long the pendulum is actually determines the time to swing back and forth for the pendulum. The arc or the weight of the pendulum does not have any impact on its swinging. This leads to a mechanical balance, which lets the division of time happen in a consistent way. In short, these clocks use the swaying motion of a pendulum to keep time accurately.

Square Quartz Wall Clock
Such clocks come with a quartz crystal. This type of crystal tends to vibrate during passage of electricity through it. It vibrates in an extremely consistent way, which ensures more reliability for timekeeping. The oscillation of quartz crystals in Square Wall Clock is referred to as a “Piezoelectric effect”. The quartz crystal and the electric circuits are known by the name “Quartz oscillator”.

Square Atomic Wall Clock
These timekeepers are typically calibrated against a resonating cesium atom’s frequency. Such clocks show time with extreme accuracy. In Boulder, Colorado, the National Institute of Standards & Technology (NIST) has an atomic clock that shows time to less than 1 second in over 60 million years. However, these are generally quite expensive and are mostly used in laboratories. However, if you have deep pockets and happen to be a stickler for punctuality, you can go for this type of Square Wall Clock.
