A shared quest for precision
Knowing where you are in space and time, setting a course and sticking to it are vital in navigation. Given its function, the watch is an essential tool for sailors to assess their position. Regarded as the most precise horological instruments in the world, marine chronometers have been certified by astronomical observatories since the 18th century. At the time, the ultimate authority for measuring chronometric precision was the Kew Observatory in Great Britain.
In 1914, the founder of Rolex, Hans Wilsdorf, had one of the brand’s watches tested by this very observatory, which certified it as a chronometer: a first in the watchmaking world for a wristwatch. Since then, renowned sailors, such as Sir Francis Chichester and Bernard Moitessier, have navigated the seas with Rolex wristwatches serving as onboard chronometers.
