Rolex Milgauss

The Rolex Milgauss Ref. 116400GV is one of the brand’s most distinctive creations — a fusion of scientific heritage, bold color, and innovative engineering. Originally designed for engineers and technicians exposed to strong magnetic fields, the Milgauss remains a symbol of Rolex’s technical mastery. The 40 mm Oystersteel case houses a magnetic-shielded Calibre 3131 movement, ensuring reliable chronometer precision even in extreme conditions. Its striking Z-Blue dial, protected by a green-tinted sapphire crystal, gives off dynamic reflections that shift under light — paired with the signature orange lightning-bolt seconds hand for unmistakable character. The result is a watch that blends professional utility with unmistakable personality.
