A watch is very important in our life, it is not only an item that tells the time, defines our personality/status, and also has many other practical even amazing functions to fill our life with joy. We love our high complications and luxury timepieces. Here we take a  look at some common functions of watches.

Some watches display the date, some display the day of the week and some display different timezones at once. It was Rolex that invented the date function in wristwatches. In 1945, Rolex Datejust became the very first automatic chronometer certified wristwatch with a date window. It was Rolex that invented the a GMT function in wristwatches. In 1955, Rolex GMT-Master became the world’s first wristwatch with a GMT function. Plus, Rolex launched the Rolex Day-Date replica , equipped with a day – and a date function in 1956. It is the first watch in the world that has the calendar windows on the watch surface and can also display the full week, which is a great technique achievement at that time.

Some watches display the chronograph function. Chronograph watch is a watch that has a timer function, indicating seconds and sometimes sub-seconds, minutes, and hours. A chronograph is basically a watch with stopwatch capabilities. It displays different counters or mechanisms for measuring elapsed time. Counters can register seconds, minutes and hours. This gives its owner the ability to time anything he wants. 

Some watches may even display a moonphase complication, which illustrates the lunar phases throughout the month. And some watches even have a compass function which is very important to use when you’re hiking or you lost your way home.  There are other functions that watches have. No matter how many functions or how amazing the  function is,  they do add intrinsic value to a watch and appeal to a collector.
