Rolex is presenting a new version of the Oyster Perpetual Milgauss with unique and symbolic aesthetics. Its green sapphire crystal marked a first in watchmaking when it was introduced on the Milgauss in 2007. Now this crystal is combined with an electric blue dial, an allusion to the emblematic lightning-boltshaped seconds hand and the watch’s technical purpose as a paramagnetic timepiece designed for engineers and scientists in the 1950s, a golden age of scientific research.
