As we had mentioned earlier, the attention to detail on steampunk inspired designs never fail to impress, and in this case, when exposed to the sun, the turbine blades on the front of the pocket watch apparently will rotate which helps to generate the necessary energy required to keep the internals of the clock going, which we guess would help to explain the name “Solar Powered Turbine Fob Watch”. However when no sunlight is readily available, you will be able to manually crank the turbine yourself. Made out of English pewter and brass, the Solar Powered Turbine Fob Watch is available for $149.
