This magnificent timepiece by Rolex was created in 1956 for engineers and technicians to resist strong interference of up to 1000 gauss, hence its name - mille that is French for thousand. The 30m water resistant case is protected with sapphire crystal. It features a round white dial that sets the stage to orange hour indicators, minute indicators and prominent luminescent hands. The link bracelet fits on the wrist with a folding oyster clasp.
