Only official Rolex retailers are allowed to sell and maintain a Rolex. They guarantee the authenticity of each and every part of your Rolex, not to mention its reliability over time, helping you make the choice that will last a lifetime.
The reliability and precision of an ordinary mechanical watch can be affected by a magnetic field of 50 to 100 gauss. But many scientists are exposed to much higher magnetic fields during the course of their work. Rolex’s solution was the Rolex Milgauss, created in 1956, the first watch of its kind. Hence the name of the watch, mille being French for thousand.
