Watch Functions

Aside from the basic function of telling accurate time through the second, minute and hour hands, some watches,such as Rolex replica,Porsche Design replica,Richard Mille replica,Zenith replica,Hublot replica and Ferrari replica watches are packaged with additional features - also known as complications - that cater to the wearer's particular lifestyle, profession or interests. A basic complication would be a calendar showing the day, while calendars that are more complicated display the day, date and month. Some watches feature a perpetual calendar that takes into account the varying number of days in a month and even leap years. Among the more specialised complications is the chronograph, which acts as a stopwatch and can measure anything from miles-per-hour to pulse rate. The tachymeter (or tachometer) enables the wearer to measure his speed over a known distance, while a watch with moon phase functionality displays the lunar phases. An avid pilot would benefit from owning a watch with an altimeter, which provides altitude measurements by responding to changes in barometric pressure. A diver will look for a watch with at least 200 metres water resistance. A person engaged in boat races (regattas) would use a sailing timer to correct his navigation and synchronise his watch with the official race timer.
