Analogue
A traditional face, marked with twelve hours, either in Arabic numerals, Roman numerals or baton markers. In fashion watches, the different marking types may be combined for a distinctive look.
Arabic numerals
Traditional numerals from 1 to 12.
ATM
Stands for ‘atmosphere’. 1 ATM is equal to 10 metres of water pressure. Therefore 2 ATM means that the watch is water resistant to 20 metres.
Baton marker
Bar shaped hour markers that take the place of Arabic numerals or Roman numerals.
Bezel
A ring around the outside of the dial. On sports watches the bezel often revolves and has markings, so it can be used to measure time or speed. It is often used by divers to measure the amount of time spent under water.
Bracelet
Most bracelets are made of metal and have links that can be removed to adjust the length.
Chronograph
A watch that has accurate timekeeping or stopwatch functions. Available in both analogue and digital formats.
- Digital chronographs use a digital display for both timekeeping and stopwatch functions, either with separate displays or by switching modes on a single display.
- Analogue chronographs have a standard analogue watch with permanent centre seconds and a separate digital display.
Chronometer
The similar-sounding terms chronograph and chronometer are often confused, although they mean different things. A chronograph has a stopwatch function, as explained above, while a chronometer watch has a high quality quartz movement that has been tested and certified to operate within a certain standard of accuracy by the COSC (Contrôle Officiel Suisse des Chronomètres).
Crown
Also known as the winder. This is a small dial on the side of the watch which can be wound to adjust the time.
Digital
A digital watch displays the time in figures that change in steps. It gives a reading in units as small as seconds and fractions of seconds.
Dual time
Good for those who frequently travel internationally, this watch allows you to display two different time zones.
Illuminated
Some watches have a special light absorbing paint on the hour and minute hands so they can still be seen in the dark. Others are illuminated by pressing a button on the case.
Kinetic
Also known as automatic watches, these use your body movement to convert kinetic movement into electrical energy and don’t require you to change the battery. The battery will eventually run down if the watch is not worn for a long period. However, some kinetic watches have a sleep function that conserves energy when the watch is not in use, and will continue to work for up to 6 months.
