There are two basic kinds of watches. Analog watches display the time through a dial with an hour hand, minute hand, and sometimes a second hand, on a dial usually divided into 12 hours, often marked by numbers or roman numerals.
|A digital watch on the other hand displays the time by hour and minutes or even seconds on an LCD or LED screen in terns of numbers or digits. The Japan Watch and Clock Association describes the two types as follows:|
Analogue watches/clocks have a mechanism to indicate time by means of mechanical structures a dial and hands (hand indication type), while digital watches have a mechanism to indicate time by means of electronic structures, such as a liquid crystal and LED (number display type)."Digital" ("digit" as a noun), representing a finger, implies a thing that can be counted on fingers, which indicates a number. On the other hand, "analogue" originally means resemblance or similarity, which indicates a continuous quantity, as the antonym of "digital."
A smartwatch is a computerized wristwatch with functionality that goes beyond timekeeping. While early models can perform basic tasks, such as calculations, translations, and game-playing, 2010s smartwatches are effectively wearable computers. Many run mobile apps, using a mobile operating system. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth or USB headset. Some models, also called 'watch phones', feature full mobile phone capability, and can make or answer phone calls or text messages.
