The reliability and precision of normal watches would be influenced by 50 to 100-gauss magnetic fields. But many scientists need to work in the environments where the intensity of magnetic fields is much higher. Rolex was devoted to seeking a solution and then launched the first Milgauss watch in 1956. And soon, the copy watches with steel bracelets became popular among the people.
The successful Rolex replica Milgauss watches have unique green sapphire-crystal glasses which are the pioneering invention. The glass matches the electric blue dial and the iconic lightning-pattern second hand perfectly. The watch case is also made of 904L steel of high anti-corrosion and easy-polished property.
Rolex copy watches with 3131 calibre have efficient protection system. This protective function is because of diamagnetic cover inside the case, which can guarantee normal operation of the movement. So only innovation and quality can stay long.
