Rolex Milgauss Watch
If you ever got a hand-me-down Rolex from someone who worked in a power plant or secret government research facility, you might have gotten your hands on an early Rolex Milgauss Watch ($7,500). Introduced in 1956 for the scientific community, the Milgauss is capable of withstanding magnetic fields up to 1,000 gauss — or more than you'd ever wish to be exposed to. Corrosion-resistant 940L steel does the trick with the case, as does an amazing green sapphire cover.
