Rolex Milgauss 116400 GV

Like many of its iconic watch families, Rolex’s Milgauss was created in 1956 with a specific market in mind: scientists, power station workers and anyone else exposed to high magnetic fields. It was designed to be able to resist fields up to 1,000 gauss (hence the name—“mille” is Latin for thousand). The watch built a solid reputation with only two models until 1988, and was happily revived two decades later in a modern re-edition that remains faithful to the original purpose and aesthetics—including the beloved lightning bolt hand. This gorgeous GV version (Glace Verte) has a green-tinted dial crystal, and uses a Parachrom-Blu hairspring for even better magnetic and shock resistance.
