Ad: Nikola Tesla Alternate Currents Mechanical Nature Watch
Electrical engineers physicists and advocates of wireless will enjoy telling time with this watch featuring a portrait of "Wizard of Wireless" and "Father of Radio" Nikola Tesla along with one of his quotes on alternate currents: "Alternate currents especially of high frequencies pass with astonishing freedom through even slightly rarefied gases. The upper strata of the air are rarefied. To reach a number of miles out into space requires the overcoming of difficulties of a merely mechanical nature." myPhysics
