Types of Watches
Analogue watches use traditional time telling “hands”.
This refers to an Analogue or Digital watch that includes a stop watch or chronograph and measures hours, minutes, seconds and fractions of seconds and can be started, stopped and reset as required.
Digital watches have no moving parts and display time with LCD (Liquid Crystal Display) or LED (Light Emitting Diode) format.
Aspects to consider when buying a watch
A watch constructed from metals resistant to the effects of magnetic fields, as magnetic fields could disrupt accurate time keeping.
Many modern watches are protected with internal cushions which lessen the effects of sudden blows.
Automatic or Self Winding
Watches that can wind themselves as the wearer’s wrist moves.
Battery powered watches usually with a battery life of 2 to 10 years depending on the type of movement used by the manufacturer.
There are several types: plastic, glass, mineral glass and Sapphire Crystal glass. These vary in scratch resistance from non scratch-resistant plastic to virtually scratch-resistant Sapphire Crystal.
Water resistant watches have special seals which protect the watch to specified pressures and depths, dirt and other outside elements. The biggest misconception is assuming that watches are waterproof. A watch is not waterproof. It is water resistant.
Every watch carries a designation on how much water the moisture seals can withstand, i.e. 30m, 50m, 100m etc. Technically, this means these watches have been water-tested to these depth levels, however, normal human diving conditions seldom exceed 30m to 50m depth levels.
It is important to note that any watch with a rating of less than 50m should not be used for swimming or diving. Watches with a depth rating of 200m or more are generally suitable for diving purposes.
