So I came across on the net one Perrelet Turbine. The dial has a rotor designed like a turbine but it can be quite distracting for some. Now, Perrelet has been making rotors on the fronts of their watches for years. But, my question is, do double rotors actually make a marked difference in energy attainment compared to having the standard one rotor on the back of an automatic watch?
