Any feature or function that a watch has, over and above its ability to tell the time, is called a complication. Chronograph is one such complication, that despite its unfortunate name, actually makes life simpler for you. Here’s everything you need to know about it, along with a few interesting facts.
#1 Essentially, all a chronograph does is keep time, exactly like a stopwatch.
The word chronograph means time writer and the first chronograph was a box with ink pens
mounted on a rotating sheet of paper. It was used to compare the performance of two horses on a track by King Louis XVIII.
#3 Another story suggests that it also existed in a rudimentary form in 1816 when Louis Moinet developed it to keep track of astronomical instruments.
#4 Soon enough, watchmakers improved on the design and encased it in a pocket watch casing. Only much later was it integrated with a watch, as having the two operate independently yet accurately was quite a task.
Apart from delighting watch collectors, chronograph watches
have been a mainstay in fields such as motoring, aviation, deep-sea diving and even naval navigation.
#6 A chronograph watch essentially has 2 or 3 sub-dials, where one nests the second’s hand of the watch, the other one tells time in tenths of a second and the third one is the stopwatches’ minute or hour counter. Two additional buttons on the dial help start, stop and reset these hands.
When Apollo 13 was on the verge of losing its 3 astronauts
on board, it was their chronograph watch that helped them calculate critical engine burn and time their re-entry to Earth’s atmosphere.
