Rolex Milgauss
The Milgauss was Rolex's answer to scientists working in strong magnetic fields — born 1956, capable of resisting 1,000 gauss (hence "milli-gauss," from the French). The signature lightning-bolt seconds hand, the green sapphire crystal of the Z-Blue 116400GV, and the discontinued status (Rolex retired the Milgauss in 2023) make this one of the cult-favorite Rolexes.
