A watch is an essential accessory for most people. It is something that everyone needs, irrespective of gender or age. Although its basic function is to tell time, it is also used as a luxury item.
With the passage of time, the technology used in watches has undergone many changes, and they are more advanced now. The traditional watches were analogue. The analogue watches are designed in a manner that they have a numbered dial with two hands, an hour hand and a minute hand, which collectively tells the accurate time. This was changed in the 1970s when a watch with a new design was introduced. In a digital watch, there are no minute or hours hands; in fact, the time is displayed on a screen in the forms of digits such as 06:30 pm. All you have to do is to look at the screen to know the exact time.
A digital watch works in the same way, as a mechanical watch, but it is powered by electricity. The source of this electricity is a small round battery, which powers the watch. A digital watch has an electronic time base, which is used to tell time accurately.
The display screen can be of two types, it may either be a light emitting diodes (LED) or a liquid crystal display (LCD). As compared to the mechanical watch, a digital watch has a counter that has the same function as that of a gearing mechanism in a mechanical watch. The counters functions in a way, that it produces numbers from zero to nine in a sequence, which enables it to keep track of the time.
The Pulsar division of Hamilton Watch Company made the first digital watch in 1970. At that time, digital watches were quite expensive, and most people could not afford them. In 1975, digital watches were massively produced, and so came in the reach of the common people. At that time, most digital watches had a red coloured display, and made use of light emitting diodes (LED). In order to see the time, you had to press down a button.
During the 1980s, the digital watch industry went through drastic changes. The most renowned brand in watches, Seiko, launched a watch with a television screen built in display. Then a renowned Japanese brand, Casio, launched the first digital watch that could translate Japanese words into English, and the other distinguishable feature was that it had a thermometer in it.
Since then, the digital watches went through revolutionary changes. There are even digital watches that enable you to store information like the telephone numbers. There are even some watches with calculators, which enable to carry out both arithmetic, and scientific functions. During the era of 1990s, the digital watches were launched that had the feature of downloading, and storing data form external sources.
The digital watches are used just for telling the time, and they do not have much appeal, as a luxury item. Many expensive brands are famous for their analogue watches, and they even have their collection range. Still the digital watches have their own function and appeal and is still very useful as it has many features that an analogue watch cannot have.
