Scientific Spirit Originally developed in the 1950s for engineers and scientists, the Milgauss was designed to resist magnetic interference. Its distinctive lightning-bolt seconds hand and green-tinted sapphire crystal have made it one of the most recognisable and unconventional models in the Rolex catalogue. Technical Character This 2008 reference features a black dial with orange accents and a smooth bezel. The Oyster bracelet is fitted with an Easylink extension for added comfort. A bold and technically distinctive model that continues to stand apart within the Rolex family.
