The world’s first watch equipped with a mechanism for thermal power generation. The thermal power elements generate electricity from the temperature difference between the body and atmosphere and store it as energy in a secondary battery. A full charge keeps the watch running for about 10 months. The Thermic generates electric power via the Seebeck effect, a phenomenon produced when heat transfers from the back of the case to the case surface. To improve energy efficiency further, a power-saving mechanism stops the second hand whenever the watch is removed from the wrist.
